The Impact

Based on socio-economic development and population growth, rapid urbanisation is currently happening in China, leading to urban expansion and land use changes. This, in turn, affects biodiversity, habitats and ecosystem services. It is therefore important to identify and assess the impact of urban development policies (UDP) on ecosystems and their components at a policy level. Ji'nan City, the capital of Shandong Province in Northern China, has been taken as a case study for assessing the ecological impact of UDP. The study found that, influenced by the traditional economy-oriented development strategy, the former UDP of Ji'nan City was mainly focused on urban socio-economic growth by speeding up the construction of urban infrastructure facilities, expanding urban built-up areas as well as strengthening the development of resource- and pollution-intensive industry, which in turn has negatively influenced the ecosystem services. The promulgation of eco-environmentally friendly UDP would contribute to protect and maintain the ecosystems and their components. Finally, recommendations for informing the legislation of new environmentally friendly UDPs and furthering the implementation of ecological impact assessment (EcIA) in China are proposed.

The aim of the work was to analyze the impact on the environment during the reconstruction of buildings. This topic will be of interest to specialists considering the problems of reconstruction of buildings in general. The article assesses the negative impact on the environment of the reconstruction of a children's clinic in the city of Moscow, and also considers the general problems that arise during the reconstruction of buildings and underground structures.

The Impact

Exploring impacts of urban expansion on ecosystem services has become a hot topic for regional sustainable development, while analyzing the ecological effects of urban expansion forms under different expansion intensities and city sizes is relatively rare. Therefore, taking a typical urban agglomeration, Shanghai-Hangzhou Bay Urban Agglomeration, as a case study, this study first analyzed the dynamics of urban expansion forms (leapfrogging, edge-expansion, and infilling) and four critical ecosystem services (carbon sequestration, food supply, habitat quality, and soil retention) in three periods from 1990 to 2019. The multiple linear regression model and zonal statistics analysis model were used to quantitatively identify the impacts of urban expansion forms on ecosystem services, taking into account different expansion intensities and city sizes. The results showed that the urban expansion trend in the study area experienced a morphological change from integration to diffusion and then to integration in 1990–2019; edge-expansion was the dominant expansion form. Food supply decreased continuously while other ecosystem services had fluctuating changes, and they all had spatial heterogeneity. The leapfrogging, edge-expansion, and infilling all had negative impacts on ecosystem services, and among them, the edge-expansion intensity had the highest influence degree in the early expansion, and the leapfrogging intensity occupied the dominant position in all influences with the expansion of urban scales. For different city sizes, the impact of edge-expansion in large-scale cities was greater than in small-scale cities in the early expansion, and the impact of leapfrogging in large-scale cities exceeded the edge-expansion in the subsequent expansion. These findings will help further understand the influential mechanisms between urban expansion and ecosystem services and provide a scientific basis for formulating reasonable urban planning.

The Impact

During the last 3 decades, developing countries especially China has experienced rapid urbanization process, which on one side have brought great leap forward of local economy as well as local social wellbeings, however on the other side such process has also led to great challenges on local ecosystem, which may jeopardize the potential of cities in these countries to meet their residents’ need and pursue more sustainable future. Therefore, a case study was taken in Yantai, a major city in Circum-Bohai Sea Region, and to assess the impact of rapid urbanization process on the local ecosystem services (ES), hence provided suggestions for pursuing more rational way of development of this city. Results showed that the decentralized pattern of urbanization, although has relatively moderate impact on Yantai’s ES, but may have substantially influences on the city’s sustainable future, therefore measures should be taken on restrain the decentralized urban expansion, reform of local authority regimes toward sustainable governance, as well as transforming regional industrial structure from secondary industry depended to more environmental friendly pattern.

The Impact

Ecological impact assessment is revealed through quantitative the impact of human activities on economic development and on human health to determine a regional ecological or environmental load capacity. Only scientific, reasonable and practical to establish an evaluation system, it may promote the healthy development of the construction industry and emerge more green construction enterprises, so as to contribute more green building community. The paper used analytic hierarchy process (AHP). With this evaluation criterion, we can evaluate green construction level of engineering construction.
