广西生态系统服务价值空间分布与生态保护对策

Guangxi Ecosystem Service Value Spatial Distribution and Ecological Protection Countermeasure

以广西90个县(市)为研究区,采用2005年广西土地利用变更数据,对照我国陆地生态系统单位面积服务价值表,测算广西各县(市)的生态系统服务价值。结果表明,广西生态系统服务价值可归纳为生态系统服务价值高的区域、生态系统服务价值中等的区域、生态系统服务价值低的区域三大类,其中,生态系统服务价值高的县(市)主要分布在桂西北山区、桂东山区、桂东南丘陵区、桂北山区、桂东北山区;生态系统服务价值中等的县(市)主要分布在桂南丘陵台地区和桂西南山地区;生态系统服务价值低的县(市)主要分布在桂中盆地、桂西岩溶山区和桂西北岩溶山区。

Taking 90 counties（cities） in Guangxi as research area,the ecosystem service value of each county（city） was measured by using land use change data of Guangxi in 2005 and comparing with Chinese terrestrial ecosystem service value per unit area table.The results showed that Guangxi ecosystem service value could be grouped into three categories： high value region of ecosystem service,mainly distributed in east,north,northeast,northwest mountainous region and southeast rolling terrain of Guangxi;medium value area of ecosystem service,mainly including south rolling terrain and southwest mountainous region of Guangxi;low value region of ecosystem service,mainly located in median basin,west and northwest karst mountainous area.
