摘　　要：土地利用类型变化是人类活动与自然环境共同作用的结果,土地利用类型演变在一定程度上体现了区域经济发展、生态等发展趋势。采用GIS技术构建土地利用多特征功能性指数等,定量、定性分析乌鲁木齐市2000—2020年21年间土地利用演变特征。分析发现:研究区2000—2020耕地面积总体减少向建设用地转移减少,建设用地呈快速增加状态;土地利用向多样化方向发展,土地利用程度增强,交通便利、人口较密集区域呈发展状态。The change of land use types is the result of the joint action of human activities and the natural environment,and the evolution of land use types reflects to some extent the development trends of regional economy,ecology,and so on.This paper uses GIS technology to construct a multi-feature functional index of land use and quantitatively and qualitatively analyzes the evolution characteristics of land use in Urumqi city from 2000 to 2020.The analysis shows that the cultivated land area in the study area decreases in general from 2000 to 2020,the transfer to construction land decreases,and the construction land increases rapidly;Land use is developing towards diversification,with an increased degree of land use.Areas with convenient transportation and high population density are in a state of development.
