基于遥感与GIS技术的山西省数字地貌分析

Digital geomorphic analysis of Shanxi province based on remote sensing and GIS technology

利用基础地貌数据,通过山西省边界矢量化,获取山西省地貌数据,并对其进行巨地貌单元、基本地貌类型、地貌成因类型分析。结果表明:山西省山地地貌占其总面积近2/3,基本地貌类型比较丰富,中海拔地貌、小起伏中山地貌分布广泛,在不同成因的地貌类型中,黄土地貌面积最大。

Through the vectorization of Shanxi Province, the geomorphic data of Shanxi Province is obtained based on the basic geomorphic data, and the geomorphic units, basic geomorphic types and geomorphic genetic types are analyzed. The results show that the mountainous landform of Shanxi Province accounts for nearly 2/3 of the total area, and the basic landform types are relatively rich. The medium-ahitude landform and the lowfluctuation landform are widely distributed. Among the different geomorphic types the loess landform area is the largest.
