摘　　要： 基于顺德区1995—2011年的土地利用详查数据和社会经济统计数据,分析了全区土地利用变化和社会经济发展对生态系统服务的影响。结果表明:(1)顺德区的土地利用变化较快,耕地、水域面积减少,建设用地、园地面积增加,林地、草地以及未利用地面积相对稳定;(2)研究期间,顺德区的生态服务价值急剧减少,由1995年的7.68?108元减少到2011年的5.48?108元,16年间减少2.2?108元;(3)基于2000年不变价分析,发现人均生态服务价值与人均GDP和人口密度间均存在显著的负相关关系,相关系数分别为–0.817和–0.932;(4)生态服务价值与耕地和水域面积呈显著的正相关关系,相关系数分别为0.667和0.881;与园地、建设用地面积则呈明显的负相关关系,相关系数分别为–0.841和–0.906。 According to the basic data of land use and the socio-economy in Shunde District, Foshan City from 1995 to 2011, the effects of land use change and the socio-economic development on the ecosystem services value in Shunde were analyzed. The results showed：（1） Land use change of Shunde was significant during the studying period; cropland and water body were decreased while build-up land and garden were increased.（2） The value of ecosystem services decreased rapidly from 1995 to 2011, which decreased from ￥7.68×10^8 in 1995 to ￥5.48×10^8 in 2011, and a net decrease of ￥2.2×10^8 was achieved during the studying period.（3） Calculated by using constant value of the year 2000, the ecosystem services value per capita and the GDP per capita, the ecosystem services value per capita and the population density had significantly negative correlation with coefficient of –0.817 and –0.932 respectively.（4） Cropland and water body had positive correlation with ecosystem services value and the correlation coefficient was 0.667 and 0.881 respectively, while the garden and build-up land had negative correlation with ecosystem services value and the correlation coefficient was –0.841 and –0.906 respectively.
