摘　　要：定量评估云南省水源涵养功能的时空演变特征与驱动力,为云南省生态环境修复提供理论依据和决策参考。基于1990—2020年7期土地利用、气象、土壤与地形等数据,运用InVEST模型对云南省各州市的水源涵养格局进行研究,并结合地理探测器与主成分系统聚类法对18个环境因子进行影响因素探究。结果表明,1990—2020年云南省生态系统以森林、灌丛和草地生态系统为主,森林与灌丛生态系统是云南省水源涵养功能的主体;1990—2020年云南省水源涵养总量与平均水源涵养能力均呈波动上升趋势;云南省各州市的水源涵养格局具有显著的地域差异性,水源涵养量:普洱市>红河州>文山州>大理州>楚雄州>曲靖市>临沧市>西双版纳州>保山市>昭通市>昆明市>丽江市>迪庆州>玉溪市>怒江州>德宏州;水源涵养能力:西双版纳州>普洱市>德宏州>临沧市>保山市>文山州>红河州>玉溪市>大理州>楚雄市>昆明市>怒江州>曲靖市>昭通市>丽江市>迪庆州;1990—2020年云南省水源涵养格局具有显著的空间异质性,水源涵养重心呈东北—东南—西南—西南—东北—东南向的倾斜“弓”字型迁移,水源涵养重点区经历了收缩、再收缩、大扩张、扩张、大收缩、微扩张的变化;云南省水源涵养异质性是多因子共同作用的结果,气象因子是导致异质性形成的关键因子,人类活动对下垫面的改造是异质性形成的最直接因素。The objective of this study was to quantitatively assess the spatial and temporal evolution characteristics and driving forces of water conservation functions in Yunnan Province,with a view to providing a theoretical basis and decision-making reference for ecological environment restoration in the province.Based on the data of land use,meteorology,soil and topography for 7 periods from 1990 to 2020,we applied the InVEST model to study the water conservation pattern of various prefectures and cities in Yunnan Province.Combined geodetector and principal component systematic clustering method,the influencing factors of 18 environmental factors were explored.The results showed that the ecosystems in Yunnan Province were dominated by forest,scrub and grassland ecosystems,and forest and shrub ecosystems play the main functions for water conservation in the province from 1990 to 2020;the total amount of water conservation and the average water conservation capacity of the province showed a fluctuating upward trend from 1990 to 2020;and the water conservation patterns of all the prefectures and cities in the province had a significant increase in water conservation.The pattern of water conservation had significant regional differences,the quantity of water conservation was in the order of Pu'er City>Honghe Prefecture>Wenshan Prefecture>Dali Prefecture>Chuxiong Prefecture>Qujing City>Lincang City>Xishuangbanna Prefecture>Baoshan City>Zhaotong City>Kunming City>Lijiang City>Diqing Prefecture>Yuxi City>Nujiang Prefecture>Dehong Prefecture,and water conservation capacity was in the order of Xishuangbanna Prefecture>Pu'er City>Dehong Prefecture>Lincang City>Baoshan City>Wenshan Prefecture>Honghe Prefecture>Yuxi City>Dali Prefecture>Chuxiong Prefecture>Kunming City>Nujiang Prefecture>Qujing City>Zhaotong City>Lijiang City>Diqing Prefecture;water conservation pattern in the province during 1990—2020 exhibited a significant spatial heterogeneity,the centre of gravity of water conservation shifted along the direction of northea
