摘　　要：土地生态系统服务价值评价对于优化土地利用格局、改善地表覆被、实现区域可持续发展,具有重要的指导意义。以特殊生态脆弱区——滇桂黔石漠化片区为研究区域,综合运用土地利用转移矩阵、价值当量法和地理探测器等方法,探究片区1990—2018年土地生态系统服务价值的时空演变特征及其驱动因子。结果表明:研究期内,滇桂黔石漠化片区城市建设成效显著,石漠化治理效果良好。建设用地和水域面积分别增加116.38%和76.40%,以石漠化裸岩石质地为主的未利用地则减少47.45%并主要转化为草地和林地。但耕地和林地面积的减少态势应引起警惕;滇桂黔石漠化片区生态系统服务价值呈逐年增加态势,生态系统服务价值由1990年的10423.82亿元逐年提高至2018年的10631.62亿元,但增长幅度较小且内部差异明显,总体维持西南较高、南部次之、北部较低的空间分异特征,生态系统功能改善仍任重道远;滇桂黔石漠化片区生态系统服务价值的空间分布差异受自然地理要素和社会经济要素共同作用,其中人类活动程度影响深刻。距离县中心、人口密度和年均气温始终是解释力排前三的单因子,且所有具备较强解释力的交互因子均包含距离县中心。Studying the temporal and spatial evolution characteristics of land ecosystem service value and the driving factors of spatial differentiation in the rocky desertification area of Yunnan,Guangxi and Guizhou,to provide theoretical reference for scientific evaluation of ecological governance effect,optimization of land use pattern,and improvement of ecosystem service function.The land use transition matrix was used to reveal the law of land use change in the rocky desertification area of Yunnan,Guangxi and Guizhou from 1990 to 2018,and the modified value equivalent method and geographic detectors was used to explore the temporal and spatial evolution characteristics and driving factors of the service value of land ecosystems.The results show as follows.During the study period,urban construction in the rocky desertification area of Yunnan,Guangxi and Guizhou developed vigorously,and the effect of rocky desertification control was good.The area of construction land and water area increased by 116.38%and 76.40%respectively,while the unused land,which is mainly rocky desertification,decreased by 47.45%and was mainly transformed into grassland and woodland.However,the decrease in the area of arable land and forest land should be alarmed.The value of ecosystem services in the rocky desertification area of Yunnan,Guangxi and Guizhou has been increasing year by year,and the value of ecosystem services has increased from 10423.82 billion in 1990 to RMB 10631.62 billion in 2018.However,the growth rate is relatively small and the internal differences are obvious,so there is still a long way to go for ecosystem maintenance and improvement.With 25°30′N latitude as the dividing line,the overall spatial variation characteristics of higher in the southwest,followed by the south and lower in the north are maintained,corresponding to the Yunnan,Guangxi and Guizhou regions in order.The differences in the spatial distribution of ecosystem service values in the rocky desertification area of Yunnan,Guangxi and Guizhou are influenced
