| 摘 要： | 基于野外调查,遥感影像辨析和GIS技术,利用DEM、地形图、沙漠化图等图件以及气象资料,对青海共和盆地坡度、坡向和地表形态类型进行了统计分析,分析了青海共和盆地风水交互侵蚀的基本格局,初步得到:1)研究区坡面的侵蚀强弱呈现垂直分带性.在各流域的分布中,沙沟河流域的坡面切沟侵蚀最为严重;2)坡向与风向的夹角决定了风在谷地...

| Abstract: | Based on field work and remote sensing and GIS technology,we statistically studied the slope,aspect and surface morphological types in Gonghe Basin,Qinghai Province,using DEM,desertification map and meteorological data. Through preliminary analysis of basic pattern of aeolian-fluvial interaction in the study area, our results show that ( 1) the different degree of slope erosion shows vertical zonality. Gully erosion in Shagou River watershed is the most serious in four wateshelds; ( 2) The angle between the... |
