摘　　要：以广西2000年、2005年土地利用现状数据为基础,基于GIS平台,综合利用ArcGIS 10.1,CLUE-S模型以及SPSS 19.0等软件,结合谢高地等对中国陆地生态系统单位面积生态服务价值表,修正计算得到了2015年广西壮族自治区生态服务价值空间分布图与生态系统服务价值表,并同1995年、2000年和2005年数值对比揭示了广西喀斯特山区生态系统服务价值时空变化规律,发现构成该区生态系统服务价值主要土地类型是耕地、林地、草地;如果保持2001—2005年的人类影响不变,2015年广西喀斯特地区生态系统服务价值将基本平稳,达到664.39亿元;生态服务价值高值区有扩大趋势,同时低值区也仍然在扩大,中值区有所缩小,特别西南地区、东北地区低值区有所扩大,要警惕建设用地扩张与辐射作用,由此可见喀斯特地区生态环境保护形势依旧十分严峻。Based on the status of Guangxi land use data in 2000, 2005 and GIS platforms, comprehensively uti- lizing ArcGIS 10.1, CLUE-S model and SPSS 19.0 software et al, and combining with equivalent value per unit area of ecosystem services in China by Xie Gaodi et al, this paper calculated and amended the values of e- cosystem services and the spatial distribution of ecosystem service value table in Guangxi, and revealed Guan- gxi karst mountainous area＇s ecosystem service value temporal variation by comparing with those situations in 1995, 2000 and 2005. Finally, it was found that the main types constituting of land area the value of eco- system services were farmland, forest land, grassland; if the human impact of change between 2001 and 2005 was been kept, the value of ecosystem services in Guangxi Karst Mountainous Area will be basically stable in 2015, will reach to 66. 439 billion （RMB） ; from the perspective of space,the high value areas for values of e- cosystem services have a tendency to expand, low value areas are still expanding, and the middle value areas will narrow, particularly in the southwest, northeast should be alerted because of the construction land ex- pansion and radiation effect, thus the eco-environmental situation is still very grim.
