Abstract:

Based on land use and land cover data, with the valuation systems developed by Xie, the ecosystem service values (ESV) of China (except Hong Kong, Macao and Taiwan Province) in 2000, 2010 and 2015 were analyzed, and their spatial and temporal distributions and variations were analyzed. The results show that ESV in China grew from 15917.1 billion yuan per year in 2000 to 16180.2 billion yuan per year in 2015. The ecosystem service value in China showed high level in the eastern provinces and low level in the western provinces. The spatial variations of ESV per capita were greater than those of ESV per unit area, but both of them decreased from 2000 to 2015, which were dominated by variations among regions. Provinces with increasing ESV concentrated in the west and the north of the country, while provinces with decreasing ESV concentrated in the east and the south.

Key words: ecosystem services, spatial variations, land use, valuation, China

摘要：

基于土地利用/覆盖数据, 应用谢高地提出的生态系统服务价值(ecosystem service value, ESV)评价体系, 对2000, 2010和2015年中国各省级行政区(不含港、澳、台地区)的生态系统服务功能价值进行评估, 并分析其空间差异的变化特征。结果表明, 全国ESV从2000年的159171亿元/年增长至2015年的161802亿元/年。我国ESV空间分布特征为东部高、西部低。人均ESV的空间差异程度比地均ESV大, 但自2000年至2015年均有所减小, 在总体差异中, 区域间差异一直占较大的贡献率。2000—2015年, ESV增加的省份主要在西部和北部, 而东部和南部地区ESV有减少的趋势。
