Green infrastructure has been used for environmental conservation and management with many similar concepts such as green-space network, green-link network, and green-ways network based on the objectives of the cities for greening. Seoul established the 2030 Seoul City Master Plan that contains green-link network projects to connect critical green areas within the city. However, the plan does not have detailed analysis for the green infrastructure to incorporate land-cover information to many structural classes. This study maps green infrastructure networks of Seoul for complementing their green plans with identifying and ranking green areas. Hubs and links that are the main elements of green infrastructure have been identified through incorporating cadastral data of 967,502 parcels to 135 of land use maps using Geographic Information System. The study extracted 1,365 of green areas that represent an area of 24,530 ha within the city and buffered these areas to identify districts as critical green areas that have hubs and links. At a city scale, the study used 103,553 of parcel data for ranking extracted 20 districts, and 17,860 of parcel data for ranking extracted 42 links connecting the districts. At a district scale, this study used 87,826 of parcel data for analyzing the status of potential links within the districts and ranking these districts for green infrastructure. This assessment analyzes the main elements of green infrastructure and suggests site prioritization for green infrastructure under variable scenarios of green and developed areas in a metropolitan city.

The goal of the study is to determine the actual areas and the geographical distri- bution of Urban Green Spaces (UGS) in Kyiv; compile and analyse the ratings of the city administrative districts by key UGS indicators and substantiate the level of comfortable living in each district according to the concept of a green compact city. The goal stems from the announcement of an official strategy of transforming Kyiv into a comfortable compact city with an attractive green infrastructure. To achieve this goal, we have calculated a number of major indicators of the modern green infrastructure of Kyiv in all ten city districts. According to the method we developed, we analysed the drawings of the urban development master plan and regulatory documents, and conducted a field survey of significant UGS sites in Kyiv. The data obtained were used to make a UGS map of Kyiv and other thematic maps. For the most accurate calculation of key UGS indicators, we processed several thousand contours in Kyiv’s cartographic base. The sizes of Urban Protected Areas (UPA) were found separately, and their share in the total city territory and of each district (Conservation Coefficients) was determined. In so doing, UPA distribution was found to be very irregular, with a total area of 174.9 km2, or about 21.2% of that of Ukraine’s capital. We analysed the ratio of the city population and the areas of green spaces in each Kyiv district. To identify districts with a different UGS coverage, we calculated the Greenness Coefficients (GC) and compiled a rating of Kyiv districts by their level of greenness, using the Greenness Coefficients Index. Significant GC variations in different city districts were substantiated. In contrast to previous studies, we calculated the provision of Kyiv residents with green zones of not merely common usage, but also with those of all other kinds, including UPA. We also calculated the Green space provision per person and compiled ratings of Kyiv districts by the Green Space Provision Index. The results were presented on a relevant map. Based on calculating the share of protected areas in the total UGS area, we found the ratings of Kyiv districts by the Green space legally protected Index. Wherein, we found significant variations among the districts by the ratio of protected areas and green spaces deprived of any legal protection. This increases their vulnerability to projected development attempts. We calculated the Integral Green Space Index (GSI) based on processing all significant UGS indicators of Kyiv. GSI allows for an integral assessment of the condition of the Urban Green Infrastructure (UGI) in Kyiv, and it is the key criterion of its compliance with modern requirements to an ideal compact city. Holosiivskyi District received the highest GSI rating. It is uniformly replete with UGS, which are provided for quality recreation and, at the same time, are protected by environmental legislation. Solomianskyi District received the lowest rating, and almost all the elements of its existing UGI require a cardinal optimisation. As a whole, the indicators we calculated can create an illusion of adequate provision of Kyiv with UGS. Actually, they are distributed very irregularly in the majority of districts. The results of our study are indicative of the presence of many challenging locations that require an extension of existing UGS and the development of new ones pursuant to the principles of compact city planning. Since UGI planning depends on the implementation of the Urban Development Master Plan, it makes sense to include the Green Space Index to the key indicators of the Kyiv Development Strategy. The draft new City General Plan should also be refined with account of the above-mentioned problems.

Green areas in cities and their ecosystem services (ES) offer residents various benefits. The range of services depends on biodiversity of a green space. The aim was to determine the relationship between biodiversity in different categories of green areas in the city and the ecosystem services, which appear in it. We made 108 relevés in the autumn and spring time, within nine categories of green areas in the Municipality of Ljubljana. In each category the range of ES was assessed based on field analysis and compared with literature assessed ecosystem services. Results showed that the category of forests differ from others. Other categories were similar to each other, in particular grassland categories. Also, a positive relationship linkage was found - more plant species mean more assessed ecosystem services in a specific green infrastructure category.

Озеленение является важнейшей составляющей целого комплекса градостроительства. Согласно градостроительным нормам насаждения должны занимать определенную площадь в жилом районе, микрорайоне, промышленной зоне, поэтому необходимо выявить их процентное соотношение по отношению ко всем зеленым территориям города и оценить их реальное состояние, дать рекомендации по уходу и содержанию. Наметить в районах города мероприятия по озеленению для того, чтобы нормы озеленения соответствовали принятым государственным нормативам. В результате этого изменится экологическое состояние города, повысится качество отдыха населения. При оценке озелененности территорий природного комплекса г. Воронежа в ходе натурного обследования территорий фиксировались различные показатели, которые позволили определить оценку существующих насаждений, устойчивость, оценку эстетического состояния насаждений. При этом использовался визуальный способ, основанный на балльной шкале оценки состояния по внешним признакам и инструментальный, основанный на измерении морфологических параметров растений. В результате исследований был определен уровень озелененности каждого жилого района и найдена общая площадь зеленых участков зеленой зоны города, которая составила 9,3 м² зеленых насаждений на одного жителя города. Таким образом, норма озеленения на одного жителя меньше нормативной. Было установлено, что обеспечение города объектами озеленения общего пользования также на 6,7 м² меньше нижнего предела рекомендуемых нормативов и на 10 м² меньше оптимального уровня озеленения. Таким образом, определено состояние зеленых насаждений на парковых территориях г. Воронежа и даны рекомендации для улучшения качественных показателей озелененности территорий, которые будут способствовать повышению декоративности и устойчивости насаждений к неблагоприятным внешним воздействиям. Greening is an essential component of a complex urban development. According to the town planning norms plantations should occupy a certain area in a residential area, district, industrial area, so it is necessary to identify their percentage in relation to all the green areas of the city and to evaluate their real condition, give advice on care and maintenance. As a result, that will change the ecological state of the city, improve the quality of recreation. In assessing the planting area of natural complex of the city of Voronezh in the full-scale survey areas recorded various measures to enable an assessment to determine the existing plantings, sustainability, evaluation of the aesthetic state plantations. This used a visual method based on the grading scale for evaluating the state of the external signs and tool, based on the measurement of morphological parameters of the plant. As a result, research has been defined for each level landscaping of residential area and found the total area of green areas green areas of the city, which was 9.3 m² of green space per inhabitant of the city. Thus, planting rate per capita is less than normative. It has been found that the provision of shared objects city greening 6.7 m² also below the lower limit of recommended standards and 10 m² level is less than optimal planting. Thus, it defines the status of green space in the park area of Voronezh and recommendations for improvement of quality indicators of green areas, which will help in creasedecorative plants and resistance to adverse external influences

The paper examines the urban development of Milan from 1859 to 1912. In the years between 1859 and 1884 the city developed in the wake of the first industrialization without a master plan and only partial plans were prepared for areas where building activities were already taking place. Planning therefore followed private initiative and even the 1876 plan by engineer Angelo Fasana was no more than a tool, without legal value, to guide and coordinate the involvement of the municipal administration. This led the Milan ruling classes to encourage the decentralization of large industries in order to avoid the onset of speculation and the resulting feared negative effects on housing areas. Following the scandal raised by the parcelling of the Lazzaretto, which began in 1880, and by the one proposed for the Piazza d’Armi, in 1883 engineer Cesare Beruto was given the task of studying an overall master plan. The gestation of the plan, long and often faced by opposition, ended with its adoption in 1889 following three earlier drafts (1884, 1885, 1888). The present paper illustrates the conceptual lines and the most important issues of the plan: the size of the blocks, the definition of the green areas and the design of the Piazza d’Armi, and outlines the results of its application over two decades at the turn of the nineteenth century. Finally, the paper discusses - taking also into account subsequent plans, such as the one of 1912 by Pavia and Masera and the one of 1934 by Albertini - the long persistence of the “radial” growth model, outlined by Beruto, and the crucial impact it has had on the image of Milan.

Ecological Potential

It is widely recognized that brownfield regeneration to green space is a sustainable form of urban development. However, it is essential to choose those brownfields that have the greatest potential to be integrated into urban green infrastructure (GI). This paper addresses how to quantitatively assess the ecological potential of coal mining brownfields at the city level, and looks at how these brownfields can be best adapted to enhance the GI system. Taking Xuzhou as an example, an ecological potential assessment method for brownfield regeneration to green space is established considering both its ecological importance and the capacity of maintaining GI connectivity. The results show that more than half of the coal mining brownfields have relatively higher ecological importance values, and only four patches play an important role in maintaining GI connectivity. The final ecological potential values of brownfield regeneration to green space are obtained by overlaying the values of ecological importance and the capacity values of maintaining GI connectivity. Then, all the brownfields are divided into five groups according to their ecological potential values, which are significantly different in each group. Around 51.35% of the brownfields have a high or very high potential for restoration to GI, which are distributed in the southeastern part of the western mining area and the central part of the eastern mining area. The presented method can assist reclamation scientists and urban planners in decision making based on quantitative analysis.

Modern urban green infrastructures are following globalisation trends and contribute to homogenization at all levels of green areas from the master plan to the finest scale. We discuss the place and role of three principal urban living spaces, the “skeleton” of green infrastructures: lawns, green walls and green roofs. This “trio” of modern GI elements provide significant ecosystem services, it contributes to biodiversity and social values; and have environmental and economic impact. The main goal of our approach to sustainable GI is to introduce a new landscape architecture style – biodiversinesque – as an alternative to the existing global homogenised picturesque-gardenesque. This new approach will combine the best achievements of innovative and alternative landscape design solutions (biodiverse lawns, pictorial meadows, walls and green roofs) and implement them on three major scales: city, intermediate neighborhood and the small biotope level.

Quantitative securing of green space in already developed cities has many practical limitations due to socio-economic limitations. Currently, South Korea is planning a green network to secure and inject effective green space, but it is difficult to reflect it in the actual space plan due to the abstract plan. This study utilizes circuit theory and least-cost path methods for presenting a green network that is objectified and applicable to spatial planning. First, an analysis of the Least-cost Path revealed 69 least-cost paths between 43 core green areas of the study site. Most least-cost paths have been identified as passing through small green areas and streams in the city. Using the circuit theory, it was also possible to distinguish areas other than least-cost paths from areas with high potential for development, areas where target species are concentrated within corridors. In particular, areas with relatively high green network improvement effects were derived within and around corridors. This study is most significant in establishing and evaluating existing urban green networks, overcoming the limitations discussed at the linear level and expanding to the area level. To increase the utilization of this study in the future, field surveys and monitoring studies on target species need to be supplemented.

Статья посвящена парковой архитектуре Хельсинки, где общая площадь парков и скверов составляет 30 процентов территории. Внимание автора сосредоточено на парках центральной части города: ландшафтных, прогулочных, ботанических, приморских, то есть предназначенных для всех возрастных групп населения. Почти все они относятся к разряду пейзажных. В качестве особенностей парков Хельсинки автор отмечает взаимодействие природной среды и архитектурных форм, а также использование рельефа местности холмисто-скального, приморского или лесистого. Важное значение имеет и тот факт, что большая часть общегородских зеленых территорий формировалась одновременно с получением городом статуса столицы Финляндии. Автор также рассматривает как обязательный элемент оформления паркового пространства Хельсинки скульптуру: анималистическую, историко-культурную, символическую. Все это в комплексе с органичным включением парковых зон в городскую среду, естественным взаимодействием с городской архитектурой, функциональностью и разноплановостью позволяет считать общегородские парки и скверы одной из доминант столицы Финляндии. The article is devoted to the park architecture of Helsinki, where the total area of parks and squares is 30 percent of the territory. The author focused on the parks of the central part of the city: landscape, recreational, botanical, coastal, that is, intended for all age groups of the population. Almost all of them belong to the category of landscape. As features of Helsinki parks, the author notes the interaction of the natural environment and architectural forms, as well as the use of the terrain hilly-rocky, coastal or wooded. Of great importance is the fact that most of the citywide green areas were formed at the same time that the city received the status of the capital of Finland. The author also considers sculpture: animalistic, historical-cultural, symbolic, as an obligatory element of designing the Helsinki park space. All this in combination with the organic inclusion of park zones in the urban environment, natural interaction with urban architecture, functionality and diversity allows us to consider citywide parks and squares as one of the dominant capital of Finland.

Urbanization is a continuous and dynamic process which has a direct impact on ecosystems and their services provided to human society. Restriction of green areas greatly accentuates urban ecological risks, having an immediate negative impact on their viability and sustainability, on life quality and population health. Increasing population density in urban areas leads to an increasing need for space. Parallel to the tentacular development of urban agglomerations, structure, architecture and design have changed, at the expense of green spaces. The development of urban areas in several European Countries (e.g., Romania, Portugal, Sweden, amid substantial demographic growth, it was made at the expense of green areas. Historical milestones of urban and peri-urban development are also key milestones in green space strategies, both in terms of development and conversion into different land-uses. This article investigates the evolution of green infrastructure in three distinct countries in Europe. In western Romania (Timisoara urban area and its neighboring peri-urban zones) we investigate the strong correlation with the evolution of urban development and the strategies developed for improving the life quality. In central Portugal, we analyze the dynamics of green infrastructures in a peri-urban catchment close to Coimbra city Centre, driven by long term urbanization. In Sweden (Malmö city), we study the history of blue-green infrastructures such as sustainable urban drainage over the past two decades and application of this in the physical planning. We will emphasize the main key milestones in green space strategies, similitudes and differences between three urban areas located in three different bio-geographical areas.
