摘要
选择河南省郸城县为研究区,以1997年、2006年的Landsat-5的TM影像和2016年的Landsat-8的OLI影像为数据源,利用ENVI5.2软件对三期遥感影像进行支持向量机分类,获取郸城县土地利用分类图,之后对郸城县1997~2016年土地利用变化用图像分析和数理统计相结合的方法做定量分析研究,分析各土地利用类型之间的相互转换关系,讨论各土地利用类型面积发生变化的主要原因。结果表明:1997~2016年近20年来,郸城县土地利用类型中耕地、林地所占面积相对较高,其中耕地面积变化较大,呈下降趋势;城乡及工矿用地、水体面积、道路面积都呈增长趋势;综合土地利用动态度为1.05%。
This study chose the Lansat 5 TM images and Landsat 8 OLI images which were acquired in 1997,2006 and 2016,respectively,as the basic remote sensing information source and performed the land use and land cover classification by utilizing ENVI software＇s support vector machine algorithm in the Dancheng County,Henan Province. Then,quantitative analysis of land use and land cover change in Dancheng County over the study period from 1997 to 2016 was carried out by image analysis and mathematical statistics method. And the main driving factors for the land use and land cover change are discussed in this study. The results shows that the area of cultivated land and forest land in Dancheng County was relatively high in the past 20 years from 1997 to 2016,and the area of cultivated land changed greatly,it represented decreasing change trend while the urban and rural land,industrial area,water area and road area were showing an increasing change trend. The comprehensive land use dynamic degree is 1. 05%.
