摘　　要：为了分析太原市晋源区生态系统服务价值变化,揭示土地利用变化与生态环境的关系,为该区域的土地可持续利用和生态环境保护提供决策建议,利用卫星遥感技术通过解译晋源区3个时相的遥感影像,结合2010年、2016年和2022年的晋源区土地利用数据,研究晋源区土地利用变化对生态系统服务价值的影响机制。结果表明:1)晋源区2010—2022年土地利用总体变化是耕地、草地、未利用地面积减少,而园地、林地、水域、建设用地和其他农用地面积增加;2)晋源区总的生态服务价值先减少后增加,其中水域和林地对晋源区生态价值贡献最大。In order to analyze the changes in ecosystem service value in Jinyuan District and reveal the relationship between land use change and ecological environment,and provide decision-making suggestions for sustainable land use and ecological environment protection in the region,the satellite remote sensing technology is used in this study to interpret the remote sensing images of three time periods in Jinyuan District,Taiyuan City.The land use data of Jinyuan District in 2010,2016,and 2022 was studied to investigate the impact mechanism of land use changes in Jinyuan District on ecosystem service value.The results show that:1)The overall land use changes in Jinyuan District from2010 to 2022 were as follows:a decrease in arable land,grassland and unused land area,while an increase in garden land,forest land,water area,construction land and other agricultural land;2)The total ecological service value in Jinyuan District decreases first and then increases,withwater areas and forest land contributing themost to the ecological value in the district.
