基于DEM的桂西北土地利用与地形关系特征分析

以都安瑶族自治县为例,利用DEM数据、土地利用现状图,以及野外实际调查资料,通过建立基于高程的地貌分区、叠加分析,分析了研究区土地利用空间分布特征及与地形因子的关系.结果表明,土地利用类型空间分布具有强烈的区域差异性,各地貌分区区域的土地利用组合不同,同一土地利用类型在不同高程区域的分布存在差异;随海拔高程增加,居民地...

Characteristics Analysis of the Relationship between the Landuse Pattern Pattern and the Terrain in Guangxi North-west Based on DEM

The thesis took the duan town as the example,based on DEM data,land use map and other materials from field survey,the study analyzed the spatial pattern of land use and the relationship between land use and topography in the research zone by creating DEM,geomorphologic zoning and altitude classification.The results showed that,spatial distribution of land use types was characterized by strong area differentiation.Even thought it was the same land use type,the spatial distribution was diversified in differen...
