摘要: 采用Landsat TM7遥感影像和SRTM高程数据、东北土壤图等数据,应用GIS水文分析、空间分析方法和遥感影像监督分类方法对东北地区基本地貌类型和土地利用类型信息进行了量化。结果表明,大兴安岭山脊线以东、七老图山山地以北的东北区面积107.27万km2,分为山地、丘陵、台地、平原4种基本地貌,所占面积比例分别为21.2%、35.6%、16.1%和27.1%。明确了松嫩平原、松辽平原和科尔沁平原的位置、界线及相互关系,改进了传统的定性划分界线的方法。土地利用类型分为林地、草地、耕地、沙地、盐碱荒地、湿地滩涂、水域和建设用地,分别占41.1%、14.0%、33.8%、0.9%、1.5%、4.7%、1.4%和2.8%。最后讨论了土地利用与地貌相关的问题。

Abstract: Supported by Landsat TM7 remote sensing images, SRTM DEM and soil maps, and using ArcGIS and ENVI software, hydrological analysis, spatial analysis and supervised classification models, the basic landform types and land use patterns in Northeast China were quantitatively analyzed. The total area across the east of Daxing’an Mountain ridge line and the north of Qilaotu Mountain ridge line was 1.0727×106 km2, and the basic landform types were mountain, hill, platform, and plain, occupying 21.2%, 35.6%, 16.1% and 27.1%, respectively. The locations, border lines, and inter-relationships of Songnen plain, Songliao plain, and Keerqin plain were clarified, and the traditional methods for qualitative determining border lines were improved. The land use patterns included forestland, grassland, cropland, sandy land, saline land, wetland, water area, and construction land, occupying 41.1%, 14.0%, 33.8%, 0.9%, 1.5%, 4.7%, 1.4%, and 2.8%, respectively. Some issues related to land use and landform were discussed.
