An ecosystem assessment is critical in linking the findings of the ecological and natural sciences on the nation’s environment to economic development and political decision-making. Since 2000 China has been experiencing rapid economic growth, accelerating urbanization, and greater resource exploitation, which have significantly altered China’s ecosystems. At the same time China has made substantial progress in ecosystem conservation and restoration in the past decade. To effectively assess the impact of China’s environmental policies and growing human drivers, the State Council of the People’s Republic of China approved the Ministry of Environmental Protection and Chinese Academy of Sciences to jointly launch the “National Ecosystem Survey and Assessment of China (2000-2010)” in 2011. The aim of the project is to determine the current status of the nation’s ecosystems, condition of ecological problems, and changes in their trends in China. The project has made notable progress in clearly describing patterns of ecosystem change and their subsequent impacts on ecosystem services, and the main problems driving ecological trends across China. The findings from the assessment will provide essential information to policy makers in developing innovative conservation policies and ecosystem management to improve ecosystems and their services in China.
