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 central-eastern and eastern China. The ecological status surveys adopted methods such as collecting, summarizing, and analyzing existing data, as well as remote sensing surveys. Through case studies of typical examples, they provided an in-depth understanding of China's ecological status, existing problems, 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 form a query system to serve ecological management and decision-making; (3) to complete ecological status reports and multimedia presentations; (4) to provide a basis for ecological functional zoning and ecological protection planning. The survey covered multiple fields, including social, economic, environmental, resources, and disasters (the western survey involved 9 categories and 193 indicators, while the central-eastern and eastern surveys involved 10 categories and 371 indicators). The statistical data were based on 1986 and 2000 as benchmark years, 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 1988 and 2000 as benchmark years, 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 typical cases such as 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 findings and reports of the "Ecological Status Survey Report of Western China" and the "Ecological Status Survey Report of Central-Eastern and Eastern China," as well as the ecological status survey results and reports from 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 summarized by the State Environmental Protection Administration. During the revision process, some content was appropriately supplemented and updated based on changes in the situation, using 2003 data.
