基于RS的九峰山历史遗留矿区土地覆被动态变化及驱动力分析

Analysis of Dynamic Changes and Driving Forces of Land Cover in the Historic Mining Area of Jiufeng Mountain Based on RS

以九峰山历史遗留矿区为研究对象,应用RS技术解译研究区2000、2010和2020年遥感影像数据,分析20年间土地覆被类型变化量、动态变化度和转移矩阵,结果表明:2000—2020年,研究区草灌区、耕地、矿区和林灌区面积变化量分别为-83.13、-0.58、41.22和42.49 km^(2),变化率分别为-30.49%、-29.44%、1177.71%和95.70%。草灌区和耕地变化较慢,草灌区主要转变为林灌区,其次被矿区侵占,耕地转变为草灌区;矿区增速极快,主要侵占草灌区;林灌区增速缓慢,主要由草灌区转入。人为因素是九峰山历史遗留矿区土地覆被类型变化的主要驱动因素。

Taking the historical mining area of Jiufeng Mountain as the research object,this paper uses RS technology to interpret the remote sensing image data of the study area in 2000,2010 and 2020,and analyzes the change amount,dynamic change degree and transfer matrix of land cover type from 2000 to 2020,the results showed that from 2000 to 2020,the area changes of grass and shrub areas,arable land,mining areas and forest and shrub areas in the research area were-83.13,-0.58,41.22 and 42.49 km^(2),and the rate of change were-30.49%,-29.44%,1177.71%and 95.70%,respectively.The grass and shrub areas and arable land changed slowly,and the grass and shrub areas were mainly transformed into forest and shrub areas,and were invaded by mining areas,the cultivated land was transformed into grass and shrub areas;Mining areas grew rapidly,mainly occupying grass and shrub areas;Forest and shrub areas grew slowly and were mainly transferred from grass and shrub areas.Human factors are the main driving factors for the change of land cover types in the historical mining area of Jiufeng Mountain.
