摘　　要：基于2010年、2015年和2022年3期Landsat遥感解译数据,采用土地利用动态度、转移矩阵、土地利用程度指数、生态系统服务价值及变化率等指标,从长时间序列角度系统分析拉市海流域土地利用与生态系统服务价值动态变化特征。结果表明,2010—2022年拉市海流域建设用地和湿地面积持续增加,农田面积持续减少,森林和草地面积呈“先减后增”趋势;在研究时段各土地利用类型呈现多动态转移,其中建设用地转入最多,主要由森林和农田转入,农田转出最多,主要转化为湿地、草地和建设用地;2010—2022年生态系统服务价值呈“先减后增”趋势,2010—2015年减少了2.71×10^(6)元,2015—2022年增加了5.60×10^(6)元;水文调节和气候调节单项生态服务价值贡献最大,水资源供给和维持养分循环贡献最小,湿地和森林是贡献的主要因子。在生态保护和修复工程实施下,拉市海流域的土地利用结构逐渐趋于稳定,流域生态系统服务价值整体呈增加趋势。Based on the Landsat remote sensing interpretation data in 2010,2015 and 2022,the dynamic change characteristics of land use and ecosystem service value(ESV)were explored by using the analysis of land use dynamics,transfer matrix,land use degree index,ecosystem service value and change rate.The results showed that from 2010 to 2022,the area of construction land and wetland in Lashihai Basin continued to increase,the area of farmland continued to decrease,and the area of forest and grassland showed a trend of“first decreasing and then increasing”;during the study period,various land use types underwent dynamic transitions,with construction land experiencing the most significant inflow,primarily from forest and farmland,while farmland experienced the most significant outflow,mainly converting into wetlands,grassland,and construction land;from 2010 to 2022,ESV showed a trend of“first decreasing and then increasing”,with a decrease of 2.71×10^(6) yuan from 2010 to 2015 and an increase of 5.60×10^(6) yuan from 2015 to 2022.Hydrological regulation and climate regulation contributed the most to individual ecosystem service values,while water supply and nutrient cycling maintenance contributed the least.Wetlands and forests were the primary contributing factors.In general,under the implementation of ecological protection and restoration projects,the land use structure of Lashihai Basin gradually stabilized,and the value of ecosystem services showed an increasing trend.
