摘要
基于2000、2010、2020 年长治市30 米分辨率遥感土地利用数据,利用转移矩阵法、土地利用变化动态幅度、趋势变化法研究长治市的土地利用变化特征,结合DEM、土地重心迁移等数据,分析长治市的土地利用特征.研究发现,2000-2020 年,长治市耕地、建设用地波动较大,耕地主要转为建设用地,新增建设用地面积382 km2.城市扩张、城镇化建设是造成这一现象的主要因素.耕地的变化速率、动态度、趋势指数均为负值,建设用地均为正值.长治市的建设用地呈卫星状扩张,直接导致耕地与建设用地重心偏移.
Abstract
Based on the 30 m resolution remote sensing land use data of Changzhi City in 2000,2010 and 2020,the study conducts the transfer matrix method,dynamic amplitude and trend change method of land use change,studies the land use change characteristics of Changzhi City,combines with DEM and land center of gravity transfer data,and analyzes the land use characteristics of Changzhi City.The study finds that from 2000 to 2020,the cultivated and construction land in Changzhi City fluctuates greatly.The cultivated land is mainly converted into construction land,and the new construction land area is 382 km2.Urban expansion and urbanization mainly cause this phenomenon.The change rate,dynamic attitude and trend index of cultivated land are all negative,while the construction land is positive.The expansion of construction land in Changzhi City is expanded with satellite shape,which directly leads to the shift of the center of gravity between cultivated land and construction land.
