Remote Sensing Mapping and Spatiotemporal Analysis of Land Use Change——A Case Study of Longgui Town in Wujiang District
Urban land use change is an important manifestation of human activities shaping surface morphology.This study is based on remote sensing monitoring data and DEM data from the second phase of land use change survey in Wujiang District,Shaoguan City from 2012 to 2022.With the help of GIS multivariate spatial analysis methods,a systematic analysis of land use changes in Longgui Town,Wujiang District over the past 10 years is conducted.Research has shown that over the past decade,there have been significant spatiotemporal changes in various land use types in Longgui Town,with an increase in the area of forest land,construction land,other agri-cultural land,and garden land.The largest increase in forest land area was 997.23 hectares,while the area of culti-vated land,grassland,and unused land showed a decreasing state.Among them,the largest decrease in cultivated land area was 673.7 hectares.In terms of terrain slope,the transformation between cultivated land and construction land and other land types is mainly reflected in low slope areas.The place with high slope is limited by the natural environment with weak human activities,and the land use change is not obvious.This study can provide data basis and theoretical reference for the comprehensive development,management,and utilization of land at the urban level in the mountainous areas of northern Guangdong,as well as geographic spatial planning.
