【摘要】 土地利用变化改变区域生态系统服务价值,进而影响区域经济可持续发展与生态环境保护。基于汾河流域1980年、2000年、2010年、2016年4期土地利用数据为基础,通过引用生态系统服务价值、土地利用动态度等指标,从整体和不同阶段上分析了土地利用变化对生态系统服务价值的影响。结果表明:(1) 1980—2016年汾河流域土地利用类型整体以耕地、草地和建设用地为主,土地利用变化是以耕地向其他土地利用类型转移的方式为主,且综合土地利用动态度呈逐渐增长趋势。(2) 1980—2016年汾河流域的生态系统服务价值呈现先增长后减少的趋势,耕地生态系统服务价值一直处于减少的趋势,退耕还林(草)政策的持续实施是导致耕地生态系统服务价值持续减少的关键原因。(3)通过汾河流域主要行政区的生态系统服务价值差异分析,1980—2016年汾河流域共有13个行政区生态系统服务价值处于增长的趋势;20个行政区生态系统服务价值处于减少的趋势。更多还原

【Abstract】 Land use change alters the value of regional ecosystem services, thus affecting regional economic sustainable development and ecological environmental protection. Based on the land use data of Fenhe River Basin in 1980, 2000, 2010 and 2016, we analyzed the impact of land use change on ecosystem service values from the whole and different stages by quoting the indexes of ecosystem service values and land use dynamics. The results show that:(1) from 1980 to 2016, cultivated land, grassland and construction land were the main land use types in Fenhe River Basin, and land use change was the main way of transferring cultivated land to other land use types; the dynamic degree of comprehensive land use was gradually increasing;(2) from 1980 to 2016, the ecosystem service values of Fenhe River Basin showed a trend of increasing first and decreasing later; the ecosystem service values of cultivated land had been decreasing; the key reason for the sustained decrease of ecosystem service values of cultivated land is the implementation of the policy of returning farmland to forestry(grassland);(3) based on the analysis of the difference of ecosystem service value in the main administrative regions of Fenhe River Basin, the ecosystem service values of 13 administrative regions in Fenhe River Basin were increasing from 1980 to 2016, while the ecosystem service values of the 20 administrative regions were decreasing.更多还原
