摘　　要：该文采用CSLE模型对松花江流域吉林段1980—2022年定量估算土壤侵蚀量,结果表明,①研究区土壤侵蚀强度主要为微度及轻度,侵蚀区主要集中在研究区东南部地区;②研究区主要土地利用类型为耕地和林地,且耕地上多为轻度侵蚀,林地遭受侵蚀的面积占林地总面积比例相对较高;③1980年到2022年研究区侵蚀面积逐渐减少,且侵蚀强度逐渐下降。The article uses CSLE model to quantitatively estimate the amount of soil erosion in the Jilin section of Songhua River Basin from 1980 to 2022,and evaluates the distribution characteristics and dynamic changes of soil erosion in the basin.The results indicate that,①The soil erosion intensity in the study area is mainly micro and mild,and the erosion area is mainly concentrated in the southeastern part of the study area;②The main land use types in the research area are cultivated land and forest land,and the cultivated land is mostly mildly eroded,while the area of forest land affected by erosion accounts for a relatively high proportion of the total forest land area;③The erosion area in the study area gradually decreased from 1980 to 2022,and the erosion intensity gradually decreased.
