摘　　要：以南宁市区1994～2004年土地利用统计数据为基础,参照中国陆地生态系统服务价值系数,分析了南宁市区土地利用变化特征及其对生态系统服务价值的影响。结果表明,10年来,南宁市区土地利用变化比较剧烈,建设用地增加明显,且占用耕地和林地现象较为突出,林地、草地和水田面积减少较多,园地、旱地面积增加明显;区域生态系统服务价值由1994年的8751．9×106元／a下降到2004年的8 636．5×106元／a,区域生态系统服务功能出现明显衰退。Taking Nanning urban as an example, based on Chinese ecosystem service value coefficient of different ecosystem types and the statistical data of land use from 1994 to 2004, the characteristic of land use change and the effects of land use change on the ecosystem service value were analyzed. The results showed that the status of land use in Nanning urban changed more dramatically. Construction land increased significantly and occupied large areas of woodland and farmland. The areas of woodland, grassland and paddy field were decreased remarkably, but the areas of orchards land and dry land were increased. The annual value of the ecosystem services was￥8 751.9×106 in 1994, and￥8 636.5×106 in 2004, which indicated the ecosystem services of Nanning urban was deteriorating obviously.
