中国国家公园建设潜在区域识别研究.

National park is a natural ecological region with national representative resources, and the construction of national park system is an important part of China's land ecological security and ecological civilization system reform. According to the dominant position of national park and the concept of ecosystem service, this paper build the comprehensive evaluation model containing six key indicators including ecological system integrity, ecological importance, authenticityty, biodiversity, natural landscape value and cultural heritage value, based on international experience, national park function and connotation of policy of national park. Single element layer analysis and multi- index superposition analysis were implemented, and then combined with China's ecological geographic area, ecological function regionalization and provincial- level administrative region, selecting factors are extracted and the potential construction areas of national parks are identified. Results show that, the high ecosystem integrity areas of China distribute obviously in large natural geographical units, including mountainous areas, forests, lakes, grasslands and other ecosystem areas. The authenticity in eastern and central regions, especially coastal areas, plains and urbanization areas, is relatively low. The species diversity in Hengduanshan, Qinling, and Xishuangbanna ecological areas is high. There are spatial concentrations of high natural landscape and cultural heritage value areas, mainly in the middle and lower reaches of the Yangtze River and along the Heihe-Tengchong Line. Those areas with high values of the ecological system integrity, ecological importance, biological diversity and ecosystem authenticity have strong characteristics of convergence. Areas with good ecosystem integrity often bear important ecological functions, have high biodiversity and are well preserved. The natural geographical areas are obviously superposed on China's three big ladders. The potential higher score regions in east and west area are of great difference in area that potential regions in the west are more continuous in space and often cross administrative boundaries. In this paper, we select 55 potential areas in total for national park construction in the future. This study can provide a methodological and theoretical reference for the reasonable layout of national park construction in China. [ABSTRACT FROM AUTHOR]
