摘　　要：对生态环境脆弱的矿产资源型城市的生态服务价值进行动态评估,对生态环境保护、经济建设及矿区生态修复具有重要意义。以山阴县为例,选取植被覆盖、植被净初级生产力、土地利用、土壤、气象、统计资料等数据,建立生态服务价值遥感评估体系,定量计算生态服务价值,分析生态服务价值的时空变化特征。结果表明:山阴县在2005—2020年,生态服务价值呈现“增加-减少-增加”的波动上升趋势,16年间生态服务价值共增加了4.34×10^(8)元。在生态服务价值构成中,维持大气平衡价值占比最大,营养物质循环价值占比最小。山阴县的生态服务价值在空间分布上由北向南呈现“低-高-低-高”的特征,南部的恒山支脉和中北部的洪涛山区域是生态服务价值的高值集中区,而低值区主要集中分布在北周庄镇-岱岳镇-安荣乡一带。2005—2020年,各土地利用类型的单位面积生态服务价值均大幅增加,且林地的单位面积生态服务价值最高,平均为10 657.36元/hm^(2),草地次之,而后依次为耕地、未利用地、水域和建设用地。该评估方法可实现生态服务价值的动态评估,为该区域生态结构优化及生态修复实施提供一定的决策依据。Dynamic assessment of ecological service value of mineral resource-based cities with fragile ecological environment is of great significance for ecological environment protection,economic construction and ecological restoration in mining areas.Taking Shanyin County as an example,a remote sensing assessment system for ecological service value was established to quantitatively calculate the value of ecological service and analyze the temporal and spatial change characteristics of the value of ecological service by selecting data such as vegetation cover,net primary productivity of vegetation,land use,soil,meteorology and statistical data.The results showed that the value of ecological services in Shanyin County showed a fluctuating upward trend of“increase-decrease-increase”from 2005 to 2020,and the value of ecological services increased by 4.34×10^(8) yuan in 16 years.In the value composition of ecological services,the value of maintaining atmospheric balance accounted for the largest proportion,and the value of nutrient circulation accounted for the smallest proportion.The spatial distribution of ecological service value in Shanyin County presented the characteristics of“low-high-low-high”from north to south.The branch of Hengshan Mountain in the south and Hongtao Mountain in the north were the high-value concentrated areas of ecological service value,while the low-value areas were mainly distributed in the area of North Zhouzhuang Town-Daiyue Town-Anrong Township.From 2005 to 2020,the ecological service value per unit area of all land types increased significantly,and the forest land had the highest ecological service value per unit area,with an average of 10657.36 yuan/hm^(2),followed by grassland,and the rest were cultivated land,unused land,water area and construction land.This method can realize the dynamic assessment of the value of ecological services,and provide a certain basis for the optimization of ecological structure and the implementation of ecological restoration in this region.
