In this study, we investigated changes in ESV in response to land use changes in Ningwu County, in eastern Loess Plateau of China. Our aim is to provide guidance for sustainable land use planning in this region. We used remote sensing to evaluate land use changes, and applied a fast, proxy-based method for evaluating ESVat three points in time： 1990, 2000, and 2010. More than 89% of the total ESV in Ningwu County was attributable to woodland and grassland. The ESV in western mountain areas show the greatest increase from 1990 to 2010, but ESV decreased the most in the low-elevation northeastern area of flat terrain These tradeoffs led to a slight net decrease （1.0%） in Ningwu County＇s total ESV. Although the decline in ESV was relatively low compared to the rate of economic growth, total ESV was much lower than global and national average levels at the end of the study period.展开更多

Due to the lack of scientific and rational sewage treatment methods for environmental protection projects, it needs to be studied and analyzed. Based on the current situation of environmental protection at home and abroad and the characteristics of the environmental protection industry, foreign advanced experience and relevant domestic policies, this paper understands that China's attention to this field is not high enough and there are certain deficiencies. At the same time, it should find out countermeasures and suggestions to solve the problems in combination with the actual situation to improve people's living standards and quality, and then promote social and economic development and achieve the strategic goal of sustainable development.展开更多

With the introduction of advanced technology and abundant resources, the introduction of social capital will effectively relieve the financial pressure on the government, and the public will also have access to better and better public infrastructure and services. However, the risk allocation and risk management of PPP model in China are still inadequate. Therefore, this paper studies the risk management of environmental protection engineering projects in China, hoping to provide a reference for the risk management model of environmental PPP projects in China.展开更多

Over the past ten years since the resettlement project started in 1993, 709,200 people or 62.76% have been resettled. Thanks to the principle of "resettlement by development," the Chinese government has paid full attention to protecting the property right, the right to employment, the right to residence and the rights and interests of disadvantaged groups. As a result, the resettlement project has given a powerful push to the overall economic and social progress and sustainable development.展开更多
