摘　　要：为揭示土地利用程度对龙门山生态系统服务价值(ESV)的影响,利用GIS空间分析技术定量分析了2000—2018年ESV和土地利用程度的时空演变规律,并利用空间自相关模型探讨了二者的相关性。结果表明,18年间研究区土地利用程度逐渐提高,增长率为0.36%,ESV总量约减少1.2亿元,各地类的ESV敏感性指数均小于1,ESV核算结果可信;该区域ESV空间正向自相关性显著:ESV高—高值区域位于汶川、北川一带,ESV低—低值区域则集中于邛崃、崇州和都江堰等地;该区域土地利用程度对ESV均为明显的负效应,即土地利用程度越高,ESV越低,土地利用方式和程度对ESV具有重要影响。In order to explore the impact of land-use on ecosystem service value(ESV)in the Longmenshan area,we used spatial autocorrelation analysis model in conjunction with GIS spatial analysis technology to quantitatively investigate the spatio-temporal evolution of ESV and land-use extent in the study area from 2000 to 2018.The results show that the land-use extent in the study area has been gradually increased in the past 18 years,with a growth rate of 0.36%,and the total ESV has decreased by about 120 million yuan.The ESV sensitivity indexes of each land cover type are less than 1,indicting the results of ESV are reliable.This region showed a positive autocorrelation of ESV space from 2000 to 2018.The ESV high-high value areas are situated in Wenchuan and Beichuan,whereas the ESV low-low value areas are concentrated in Qionglai,Chongzhou and Dujiangyan.The ESV value is significantly influenced by the mode and extent of land-use in this area.
