摘　　要：土地利用变化及遥感监测特征分析对于区域经济协调发展和生态文明建设具有重要意义。结合韶关市近10年的多时相Landsat TM遥感影像数据,从韶关市武江区土地利用动态度和利用状态指数两个维度,探究土地利用的时空演变和变迁原因,研究表明:武江区耕地面积减少明显,年平均缩减率为2.41 km2,而建设用地和林地面积增加,增速由城区向外逐渐降低;耕地的状态指数在-0.55处波动变化,表明耕地呈现出缩减的趋势,建设用地在2010—2015年状态指数达到峰值0.91,增速较快,在2015—2020年随着政府对生态文明建设的重视,建设用地增速放缓,林地面积增加,武江区经济和生态文明协调发展趋势向好。The analysis of land use changes and remote sensing monitoring characteristics is of great significance for the coordinated development of regional economy and the construction of ecological civilization.Based on the multi temporal Landsat TM remote sensing image data of Shaoguan City in the past 10 years,this study explores the reason of the spatiotemporal evolution and change of land use from the two dimensions of land use dynamics and utilization state index in Wujiang District,Shaoguan City.The study shows that the cultivated land area in Wujiang District has significantly decreased,with an average annual reduction rate of 2.41 km2,while the construction land and forest land area have increased,and the growth rate gradually decreases from the urban area outward.The state index of cultivated land fluctuates at-0.55,indicating a trend of reduction in cultivated land.The state index of construction land reached a peak of 0.91 from 2010 to 2015,with a fast growth rate.From 2015 to 2020,with the government's emphasis on ecological civilization construction,the growth rate of construction land slowed down,the area of forest land increased,and the coordinated development trend of economy and ecological civilization in Wujiang District improved.
