- 摘要:
- 20世纪80年代起，GIS技术开始应用于我国水土保持领域。该文是在GIS和RS的支持下，利用孤山川流域2012年9月高分辨率（0.38 m）航空影像、流域周边200 km范围内13个雨量站62 a的降雨数据、DEM（5 m）、以及土壤类型图等数据，结合孤山川流域特征，运用CSLE模型对黄土高原孤山川流域土壤侵蚀进行了定量研究和土壤侵蚀强度分级，并对侵蚀结果进行空间分析。结果表明：孤山川流域年侵蚀总量为274.89万t，年均侵蚀模数为2 161.06 t/（km2·a），其中由微度到剧烈侵蚀的面积比例依次递减；随着植被覆盖度的降低以及坡度的增加，其侵蚀程度越来越严重；另外土地类型为裸地、荒草地等的水土保持效益较差，其侵蚀程度明显高于流域年均侵蚀。
- Abstract:
- Since 1980, GIS has been applied into the domain of soil and water conservation in China. By support of GIS and RS, this paper took the high-resolution aerial images (0.38 m), the rainfall data from 13 stations for 62 years which covers 200 km range of this region, DEM (5 m) and soil type map of Gushanchuan watershed, combined with characteristics of this study area, figured out the soil loss modules quantitatively with the CSLE model and graded it by the standard. Based on the results, we had conducted spatial analysis. The results showed that soil erosion of Gushanchuan watershed amounted to 2 748.9 thousand tons in 2012 and the average soil erosion modules was 2 161.06 t/(km2·a), the area proportion of soil erosion decreased from slight to dramatic level. By analyzing, the soil erosion modules increased dramatically with the decrease of vegetation coverage and the increase of slope; in addition, the benefits of soil and water conservation of the land use types like bare land or wild grassland and so on were poor, and the average soil erosion modules of these land types was dramatically higher than that of this region.
