摘　　要：基于生态系统服务价值评估体系,选取2005、2010、2015和2018年4期遥感影像获取的土地利用/覆盖数据,研究云南省129个县(市、区)生态系统服务价值的空间格局及时空演变特征。结果表明,云南省土地利用类型中森林、草地及旱地占所有土地利用类型的绝大部分;研究期整体结构变化较小,建设用地及水域呈持续增加态势。云南省生态系统服务价值持续缓慢上升。单位面积生态服务价值时间上呈微弱增长态势,空间上呈现西高东低、中西部地区偏低的特征。人均生态服务价值时间上呈微弱下降态势,空间上呈现西高东低、南北中部地区偏低的特征。Based on the evaluation system of the ecosystem service value,land utilization and cover data attained by remote sensing images in four phases of 2005,2010,2015 and 2018 was selected to study the spatial patterns and spatio-temporal evolution characteristics of the ecosystem service value of 129 counties(cities,districts)in Yunnan Province.The result showed that forest,grassland and dry land account for the vast majority of all land use types in Yunnan Province.The overall structural change in the research period was relatively slight,and construction land and water area showed a trend of continuous increase.The ecosystem service value of Yunnan Province continued to rise slowly.The ecosystem service value per unit area showed a slight increase temporally,and was spatially high in the east and low in the west,relatively low in central and western regions.The ecosystem service value per capita showed a slight downward trend temporally,and was spatially higher in the east and lower in the west and lower in the north and south central regions.
