摘　　要：城镇土地利用在一定程度上,反映城镇特征演变趋势,本研究基于濂溪区2017年和2020年2期航空正射DOM数据,并结合2020年实地调查数据,先将外业13种国土区划实际调查类型,根据本文研究内容划分为7种类型;通过GIS分析方法,利用转移矩阵对研究区的土地利用类型变化特征进行分析;结果表明:对比两年的土地利用变化中,增加最多的地物类型依次是:林地>耕地>水域>建设用地;减少最多的地物类型依次是:建设用地>水域>林地>耕地;本研究可以在一定程度上揭示:各种土地资源在地域以及时间和空间配置上是否合理以及是否匹配,进而可以对国民经济健康发展提供参考意见。To a certain extent,urban land use responds to the evolution trend of urban characteristics;this study is based on the 2 phases of aerial ortho-DOM data of 2017 and 2020 in Lianxi District,and combined with the field survey data of 2020,firstly,13 types of actual survey types of external land zoning are divided into 7 types according to the research content of this paper;through GIS analysis method,the land use of the study area is analyzed by using the transfer matrix.The results show that in comparing the land use changes in two years,the most increased land use types are:forest land>cultivated land>water area>construction land;the most decreased land use types are:construction land>water area>forest land>cultivated land;this study can,to a certain extent,reveal:whether the various land resources are reasonable and compatible in terms of geographical,temporal and spatial allocation,this study can,to a certain extent,reveal whether the geographical,temporal and spatial allocation of various land resources is reasonable and compatible,and thus provide reference for the healthy development of the national economy.
