Assessing the supply and demand of urban green space (UGS) ecosystem services (ESs) can provide relevant insights for urban planning. This study presents an analysis method for the spatial distribution of UGS ES supply and demand at administrative unit and 1-m grid scales and directly compares the matches of ES supply and demand in spatially explicit maps at two scales. Based on the analysis results at administrative unit scale, administrative units with an unbalanced UGS ES supply and demand were divided into three types: (Ⅰ) lack of green space; (Ⅱ) unreasonable green space structure; (Ⅲ) comprehensive, and different optimization schemes were put forward. According to the analysis results at 1-m scale, the regions with an unbalanced ES supply and demand of an administrative unit were divided into the following: (1) severe ES shortage area; (2) moderate ES shortage area; (3) mild ES shortage area, and the severe ES shortage area was taken as the UGS optimization area. We take the UGS within the 5th Ring Road of Beijing as an example and propose suggestions for optimizing the UGS pattern based on the evaluation of the supply and demand of UGS carbon sequestration services and purification services for particulate matter with an aerodynamic diameter <2.5 µm (PM2.5). This study provides an easy-to-use evaluation method for the spatial distribution of UGS ES supply and demand and proposes different optimization suggestions for the unbalanced area, thus playing a role in UGS construction activities and green space structure optimization.

Forestry and urban green space governance experiences rapid changes due to bottom up environmental pressure and top down changes of legislation. To deepen our understanding of crafting preferable environmental reactions towards environmental pressure, we introduced the perspective of environmental street-level bureaucrats (SLBs) and explored it using Oliver’s strategic response framework. Drawing from case studies on the governance of the moose and urban green space in Poland, we investigated the complex and mediating sphere of SLB “policy intentions” in environmental governance. We argue that SLBs can distance themselves from new expectations if these are perceived as “socially constructed” and potentially disturbing for SLBs’ professional routines. Such limited or moderated reactions can be a coping mechanism of SLBs trying to balance a complex landscape of various, even contradictory pressures. Our findings break the monolithic-type image of a ‘decision-maker’ into complex web of interrelations between administrative units and political structures. They also suggest a need of new forms of environmental (post-) bureaucracy to reinforce social trust and to deal with ambiguities of nature.

Abstract Rapid urban growth can exert negative effects on the natural environment due to the loss of naturally vegetated areas, loss of biological diversity, deforestation and soil erosion. The condition of cities is inherently linked with the natural environment which has a positive influence on health, social relations, human welfare and economic activity. Urban areas should abound in green spaces, and should also be easily accessible to the general public. The aim of this study was to determine the spatial distribution, influence and quality of urban green spaces on the example of the city of Tczew in northern Poland. The proposed methodology can be applied in cities of a similar size and urban structure to promote rational management of urban green space in line with the principles of sustainable development and spatial order. The Green-Space Record, a useful tool for inventorying urban green spaces, was developed to pursue the main research goal. The information accumulated in the Record constitutes valuable input data for further analysis, including the determination of the area, distribution, influence and quality of urban green spaces. The results of the analysis revealed that urban green spaces occupy more than 19% of Tczew’s territory, which is equivalent to 70.6 m2 per resident. Managed green spaces span the area of only 66.75 ha (11.31 m2 per resident) and are unevenly distributed in the city. More than half of these areas are found in the Stare Miasto (Old Town) district, whereas two residential districts (Gdańska, Prątnica) are completely devoid of public greens. The quality of urban green spaces is generally satisfactory in Tczew; however, not all residents have equal access to high-quality public greens.

Based on analyzing the psychology reception of informants for external space of hospital, a novel landscape quantitative evaluation method was proposed in this study. An external space of hospital was selected and researched for illustrated the proposed method. After investigating the psychology reception from informants, Kansei words were designated. Then, a model and a quantify analysis were carried out. Next, according to quantify analysis results, the external space of hospital was evaluated objectively. This study resolved the traditional concept that landscape evaluation owing to feelings. Therefore, this study has a big significant on providing more theoretical research and design methods for not only external space of hospital but even of urban green space design in future.

Urban green space plays an important role in beautifying the environment, improving the quality of life of residents, and promoting sustainable urban development. Rapid urbanization has led to great changes in the spatial structure and layout of urban green space. It is urgent to put forward the sustainable development strategy of green space through the research on the change of urban green space. Based on the geographical spatial differences of urban green space and integrating the factors of economy, society, industry, land use, and the environment, we constructed a research framework of “space-supply-demand” integration of urban green space by GI and geodetector methods, and we conducted an empirical study on the spatial–temporal changes of urban green space and its driving mechanism in prefecture-level cities along the Yangtze River Economic Belt in China. First, the urban green space along the Yangtze River Economic Belt is concentrated in spatial distribution, while uneven development appears in urban greening among the zones. Second, the influence of different factors on urban green space change varies greatly and can be divided into three types: key factors, important factors, and auxiliary factors. The driving mechanism of the spatial distribution of urban green space supply and demand is quite different, but urban population and commercial service facilities land are their key influence factors, having a comprehensive influence on the spatial–temporal changes of urban green space. Third, the factors are classified into three categories of high, medium, and low levels according to the mean of interacting forces; in particular, the factors of per capita GDP, utility land, industrial smoke (dust) emissions, and other factors have a very strong interactive effect with other factors. Fourth, according to the spatial distribution characteristics of urban green space and its driving mechanism, this paper puts forward planning and policy suggestions, providing reference for other areas to deal with the green space change.

In recent years, with the accelerating process of urbanization, economic and social fields has profound changes in the ever-changing urban landscape. The urban regional loss of Characteristic Features is increasingly plaguing the development of the city. Exploring the city's new green development model and strengthening the city's character Environment Protection and as such become increasingly important. Taking the "198 area" construction in Chengdu for example, summed up the general law of the Chengdu Plain area of urban green space structure to expand, and thus proposed to design strategy adapting to the Chengdu region's urban green space, That is a way of exploration for expansion of urban green space.
