摘　　要：对土地变化规律的掌握是科学规划都市圈空间结构的基础,有利于促进都市圈的协调发展。以兰州都市圈为研究对象,运用GIS空间分析方法,对兰州都市圈20年来的土地利用格局、土地利用速率、转移矩阵开展研究,揭示兰州都市圈土地利用变化特点及规律。结果表明:兰州都市圈在2000年~2020年的20年间,土地利用在空间上朝着复杂化多样化的方向发展;城市增长显著而不平衡,农田流失巨大;建设用地扩张迅速,面积逐年增加,空间上呈现集中面积增大的特点;兰州都市圈土地利用类型相互转换的过程复杂,不同时期表现出较大差异。Mastering the law of land change is the basis of scientific planning of the spatial structure of metropolitan area,which is conducive to promoting the coordinated development of metropolitan area.Taking Lanzhou metropolitan area as the research object,and using GIS spatial analysis method,the land use pattern,land use rate and transfer matrix of Lanzhou metropolitan area in the past 20 years were studied to reveal the characteristics and rules of land use change in Lanzhou metropolitan area.The results show that land use in Lanzhou metropolitan area has developed in a complicated and diversified direction in space during the 20 years from 2000 to 2020.Urban growth has been significant and uneven,and there is a huge loss of farmland;The expansion of construction land is rapid,and the area is increasing year by year,showing a concentrated increase in space;The conversion process of land use type in Lanzhou metropolitan area is complicated,and there are significant differences in performance at different times.
