| 摘 要： | 以全国第二次水土流失遥感调查数据为基础,在GIS技术支持下,对淮河流域土壤侵蚀的空间分布特征进行了初步的研究;同时对流域不同土壤条件下土壤侵蚀的空间分布进行了定量分析,并以土壤侵蚀危险指数(soil erosion dangerous index,SEDI)评价分析了流域分县土壤侵蚀强度的空间分布。结果表明:粗骨土、棕壤等山地土壤侵蚀严重;流域土壤侵蚀以水力侵蚀类型为主,总体上侵蚀程度轻微,但局部地区仍然十分严重。在新的治淮高潮与规划中,应重视水土保持工作。

| Abstract: | With the aid of the GIS technology,spatial distribution of soil erosion in the Huaihe River Basin was analysed and so was the spatial distribution of soil erosion intensity based on the soil erosion dangerous index system (SEDI). Results showed that: 1) mountain soils,such as cinnamon soil and coarse soil,are more easily eroded than the other type soils in the basin; and 2) although soil erosion in the basin is not serious in general,some mountain areas in the upstream still have a high value in the SEDI. Attention should given to soil and water conversation in the new campaign of harnessing the River. |
