基于遥感监测的陕西省关中地区土地利用变化分析

Analysis of Land Use Change in Guanzhong Area of Shaanxi Province Based on Remote Sensing Monitoring

基于遥感监测信息成果,以关中地区为研究区域,进行土地利用变化统计,并对土地利用变化的驱动因素进行分析,结果表明:2020—2021年,研究区域平原地区耕地增多,主要是园林地变为耕地;西安市周边及西咸新区建设用地增多;西安城区宅基地拆除量较大,主要集中在浐灞生态区和曲江新区。西安中心城市建设步伐加快、严守粮食安全底线和关中移民搬迁是主要驱动因素。研究结果对关中地区的耕地保护、城镇化进程以及土地利用变化有一定的参考价值。

Based on the results of remote sensing monitoring information in Shaanxi Province,taking the Guanzhong area as the research area,the statistics of land use change are carried out,and the driving fac⁃tors of land use change are analyzed.The results showed that:from 2020 to 2021,the cultivated land in the plain area increased;mainly from garden land and woodland to cultivated land;the construction land around Xi’an City and Xixian New District increased;the demolition of residential land in Xi′an urban area is relatively large,mainly concentrated in Chanba Ecological District and Qujiang New District.The acceleration of the construction of Xi′an′s central cities,strict adherence to the bottom line of food secu⁃rity and the relocation of migrants from Guanzhong are the main driving factors.The research results have certain reference value for cultivated land protection,urbanization process and land use change in Guanzhong area.
