The City

The city is one of the most specific ecosystems of the modern biosphere. The combination of natural and artificial components and elements of the city have made it a complex system of ecotopes with various levels of anthropogenic transformation. Still the structure of urban ecosystems includes some patches of undisturbed or minimally disturbed landscapes, which may be considered the home for the most abundant part of urban biocenosis – the urban avifauna. Therefore, in this research the concept and features of urban zoocenosis in specific application to avifauna of the Kyiv urban system have been considered. A modern city if found to offer a range of benefits for birds, including food, shelter, and higher temperatures over the year and lower predator pressure and competition. However, the level of food quality as well as the condition of environment components are low and impose real health threats. Physical pollution, in particular noise and electro-magnetic impacts are also serious disturbing factors. Considering these factors, the ecotopes most suitable for birds have been defined among the parks, forests, lakes and cemeteries of the city – total 59 objects. In order to assess their comfort for birds, the specific ranking scale has been developed. The parameters taken into consideration in the course of assessment are as follows: general spatial characteristics (size and fragmentation of the territory), vegetation quality (covered territory, height and age of trees), forage availability and diversity, hydrographic situation (access to water bodies), environment quality (level of water and air pollution, noise pollution, non-organic wastes directly at the site), human pressure (density of people moving, area with artificial covers, level of anthropization), bird supporting elements and activity, and also predation pressure. According to the obtained result the forests around and its residuals inside Kyiv are the least transformed and consequently the most comfortable for the support of birds diversity. They are followed by cultivated semi-natural areas, which comfort declines as the levels of recreational pressure, human presence and proximity to the city center increases. Finally, the last in the list are small parks or cemeteries, cut off from water bodies or water bodies lacking dense vegetation. An important issue, showed by personal visual observations, is that the activity of humans aimed at support of birds communities within area of any status is proved to be more important as compared to obvious disadvantages seen at certain areas.

AbstractPeculiarities of alien macrophytes invasions into aquatic ecosystems located at urban landscapes were investigated on an example of water bodies, rivers and streams located within the Kyiv City (Ukraine). There have been recognised seven species of alien aquatic macrophytes established at the territory of Kyiv City, representing 11% of the hydrophilic flora of the city. The representatives of the recent invasions Egeria densa, Elodea nuttallii and Pistia stratiotes in comparison with Elodea canadensis were characterized by a wider ecological valence concerning the contents of nitrogen compounds in water. Significant variability of morphometric parameters of coenopopulations of alien species formed in different environmental conditions was recognised. There was observed that the individuals of Pistia stratiotes from eutrophic water bodies formed significantly larger surface organs, and the individuals from meso-eutrophic reservoir had a larger number of leaves in the rosette, and more numerous and longer roots. The alien macrophytes species dwelling in the water bodies of the city were characterized by wide ecological amplitudes, high stress tolerance, high reproduction rate, high naturalization degree, allowing these species to use the resources of their new environment inaccessible for the local species and significantly affecting the ecosystem homeostasis and transformation.

The pandemic of coronavirus disease (COVID-19) led to the need for drastic control measures around the world to reduce the impact on the health of the population. The confinement of people in their homes resulted in a significant reduction in human activity at every level (economic, social, industrial, etc.), which was reflected in a decrease in environmental pollution levels. Studying the evolution of parameters, such as the level of environmental noise caused by vehicle traffic in urban environments, makes it possible to assess the impact of this type of measure. This paper presents a case study of the acoustic situation in Cáceres (Spain) during the restriction period by means of long-term acoustic measurements at various points of the city.

With the continuous expansion of urban scale, blindly increasing or controlling transportation infrastructure possibly creates a short board in an urban system. In this study, a macro traffic integrated system was constructed according to a city's economic size distribution and transportation infrastructure. The planning strategy of traffic, industry, space interaction and coordinated development was put forward. Through theoretical model, the evolution mechanism between transportation infrastructure and economic scale distribution was revealed. Starting from the center of the city and inter city level, China's new urbanization strategy was implemented, and a comprehensive transportation system model was built. The traffic planning in Singapore was taken as an example, and the solution to traffic problems such as congestion, traffic jam, and distance was obtained. Practice has proved that the rational and effective urban transportation infrastructure construction can effectively promote the coordinated development of economy and resources, and comprehensively enhance the level of integrated transport services.

Abstract As a reaction to the complex global crisis, the notion of ecological urbanism has emerged in order to understand and attend the inaccuracy between the urban system and the environment of which it is a part. This article suggests that the form we perceive the city-nature relation deeply determines the praxis of urbanism arguing that the problem of ecological urbanism is essentially epistemological and ethical. Accordingly, the article introduces the concept of “landscape ecosophy” through which not only is possible to understand the indivisible connection of perception and socio-ecological practices, but also help us to reconnect the praxis of urbanism with a relational epistemology and landscape. The article empirically seeks to interpret how the Villarrica and Pucón urban system inhabitants in the Araucanía Region of Chile perceive and relate with the mountain and lacustrine landscapes in their daily practices of inhabitation. To achieve this, an ethnographic methodology is used. The discussion central line is represented by the question, ‘So close, but so far?’, as in spite of the fact that both cities are deeply connected to the landscape, their socio-cultural constructions are defined by the notions of disconnection and a lack of awareness. On the other hand, in a sort of circular causality, the article also identifies how certain urban initiatives may not only imply a reconnection between the urban system and the landscape of which it is a part, but also contribute to trigger the emergence of deeper landscape ecosophies.

This work is focused on the diagnosis of behavior, from the point of view of control emissions and noise level, of a power Turbogas plant during the process of commissioning, to guarantee that its operation complies with national and international standards. The environmental diagnosis of the power plant was developed as part of the performance evaluation of the unit. The conditions of the unit evaluation include operation at base load and partial load, as well as time periods for load changes. The evaluated power plant consists of an aeroderivative gas turbine installed in a simple cycle, operating with a cooling system (chiller) installed in the urban zone of Mexico City. Therefore, it should comply with the legislation and regulations of the city concerning air pollution and allowed noise, besides the international standards established by the manufacturer. The study includes emissions measurements using a Continuous Emissions Monitoring System installed in-situ, previously calibrated and checked during and after the test which was found inside the permissible deviation of 3%. Measurements were recorded at intervals of 5 minutes during test periods of 110 minutes for each load and 45 minutes for load changes. On the other hand, noise pressure evaluation was carried out in near field as well as far field produced by the power plant during operation. Measurements were carried out by using precision instruments installed specifically for it. A temporary system for obtaining data was used to monitoring the environmental conditions every 30 seconds. It was possible to verify that the turbogenerator complies with all noise levels and contaminant emissions requirements and regulations according to the limits established by the manufacturer and national and international standards.

Correlational Model

The article is devoted to the interdependent identification of the city and park, which is carried out visualizing the opposition of their essential senses. In order to manage the traditional models of their consideration as separations, situationally constituent within the territorial union, the bases for examining the city as a space for the restoration of the human being and the need for its adequate, ontologically based, interdisciplinary studies, have been analysed. In this context, the park is considered as a visual legitimator of the city; the city is like the open dynamic structure that is in need of different, including indirect identificators. In such a way, a new – correlational – model of their study has been proposed, built on the visual ability to fix and covey the meanings. The visions of the city as the dominant territory of modern human implementation have real foundations resulting in the development of the relevant theoretical discourse, which is intended to find correct explanations. At this point, there is a connection of the city in its comprehensive value with the unified human being, which is the epicenter of the human matter realization – and in the processes of its permanent resurrection, and its own creativity as well. The force field of their attractive interaction foremost are man-made locations of the unutility nature, which represent the internal resource of decoding the humanistic symbolic signs. Absolute leaders in this essence are the parks designated in the city-building in the capacity of all recreational areas. In the visible picture of the city – its multivisuality – they have special words expressed by the way of visualization. Their use is optics directed to the depth of the human being. The park, built into the urban system, sharpens it as much as possible, facilitated by the controversy with the garden, in the visual text of which it fulfills a human saving function. Simultaneously, the park visions crystallize the semiosis of the city as a space of life-saving pragmatics.
