摘　　要：研究利用2000、2010、2020年3期Globeland 30土地覆盖数据,结合资料收集、现场调研、土地利用转移矩阵法、土地利用动态度法等研究方法,分析2000、2010、2020年土地利用变化特征;根据2007—2020年景电一期灌区社会经济数据,运用SPSS主成分分析法对土地利用变化及驱动力进行分析。结果表明:灌区地类主要以耕地和裸地为主,占总面积的85%以上;2000—2010年,人造地表、湿地、水体面积分别减少14.74 km^(2)、0.97 km^(2)、0.13 km^(2);2010—2020年,人造地表面积增加36.35 km^(2);整个研究期(2000—2020年),灌区综合土地利用动态度为0.25%,人造地表和水体面积分别增加21.61 km^(2)和0.48 km^(2);景电一期灌区土地利用变化主要驱动力为产业、经济和人口变化。研究成果可为灌区水土资源高效利用奠定基础。The study utilized three phases of Globeland 30 land cover data from 2000,2010,and 2020,combined with research methods such as data collection,on-site research,land use transfer matrix method,and land use dynamic degree method,to analyze the characteristics of land use change in 2000,2010,and 2020.Based on the socio-economic data of Jingdian Phase I irrigation area from 2007 to 2020,the SPSS principal component analysis method was used to analyze land use change and its driving forces.The results show that the main types of land in irrigation areas are arable land and bare land,accounting for over 85%of the total area;From 2000 to 2010,the area of artificial surface,wetlands,and water bodies decreased by 14.74km^(2),0.97km^(2),and 0.13km^(2),respectively;From 2010 to 2020,the artificial surface area increased by 36.35km^(2);During the entire research period from 2000 to 2020,the dynamic degree of comprehensive land use in the irrigation area was 0.25%,with an increase of 21.61km^(2) in artificial surface and 0.48km^(2) in water area,respectively;The main driving forces of land use change in the Jingdian Phase I irrigation area are industrial,economic,and demographic changes.The research results can lay the foundation for the efficient use of water and soil resources in the irrigation area.
