Features: From 2000 to 2002, the State Environmental Protection Administration, in conjunction with the National Bureau of Surveying and Mapping, the Ministry of Land and Resources, the National Bureau of Statistics, and the governments of provinces, autonomous regions, and municipalities directly under the Central Government, organized ecological status surveys in western China and the central and eastern regions. The ecological status surveys employed methods such as collecting, summarizing, and analyzing existing data, as well as remote sensing surveys. Through case studies, they provided an in-depth understanding of China's ecological status, the problems it faces, and their causes. The main objectives were: (1) to grasp the ecological status and its dynamic changes; (2) to establish a basic ecological status database and preliminarily develop a query system to serve ecological management and decision-making; (3) to complete ecological status reports and multimedia presentations; and (4) to provide a basis for ecological functional zoning and ecological protection planning. The survey covered multiple fields, including social, economic, environmental, resource, and disaster-related aspects (the western survey involved 193 indicators across nine categories, while the central and eastern survey involved 371 indicators across ten categories). Statistical data were based on the years 1986 and 2000, primarily derived from surveys conducted by China's statistical, agricultural, forestry, water, environmental protection, and land and resources departments since 1949, covering areas such as agriculture, forest resources, soil erosion, desertification, land resources, rural non-point source pollution, etc. Remote sensing surveys were based on the years 1988 and 2000, extracting and analyzing thematic information on land degradation, urbanization, coastal zones, wetlands, etc. Case studies focused on China's prominent ecological issues, with over 100 typical areas established, including dozens of cross-province and cross-river basin cases. These included forests, lake wetlands, ecological degradation, biodiversity, water resource utilization, invasive alien species, rapid urban development, coastal zones, scenic tourism, and genetically modified biotechnology safety. This book is based on the results and reports of the "Ecological Status Survey of Western China" and the "Ecological Status Survey of the Central and Eastern Regions," as well as the ecological status surveys of provinces, autonomous regions, and municipalities directly under the Central Government (excluding Taiwan Province, Hong Kong Special Administrative Region, and Macao Special Administrative Region), compiled and compiled by the State Environmental Protection Administration. During the revision process, some content was appropriately supplemented and updated based on changes in the situation, using data from 2003.
