摘　　要：土地利用变化对生态系统的影响的研究是目前可持续发展和生态学研究的热点之一.该研究以1996～2008年桂平市土地利用规划数据、变更数据和第二次土地调查数据为依据,对该区域土地利用变化特点进行了分析,并结合该区域不同时间维度的生态系统服务价值及其变化情况,对桂平市土地利用变化对生态系统服务功能的影响进行了探究.结果表明：1996～2008年桂平市土地利用结构变化中最为明显的是园地,其次为草地.土地利用变化导致生态系统服务总价值增加了约9 043.05万元,其中林地对生态系统服务总价值的贡献最大,各单项服务价值变化也较明显.The influence of land use change on ecosystem research is currently one of the hot topics in the study of sustainable development and ecology. Based on land use planning data, change data and the second data of Guiping City during 1996 - 2008. the characteristics of re- gional land use change were analyzed, combined with ecosystem service function and the change in different time dimensions, the effects of land use change in Gulping City on ecosystem service function were explored. The results showed that in Gulping City during 1996 -2008, the most obvious change of land use structure is garden plot, followed by grassland. The total value of ecosystem services increased by about 90 430 500 yuan, and the total value of forest ecosystem services was the largest, and the value of each individual service was also obvious.
