黄河流域(河南西部)土壤侵蚀环境特征研究

Environmental Characteristics of Soil Erosion of Yellow River Area(West of Henan)

豫西黄河流域是黄河流域土壤侵蚀较强烈的地区之一,严重的水土流失不仅使区内土壤贫瘠、生态环境日益恶化,也是黄河下游泥沙、洪水问题的主要诱因。通过土壤侵蚀地质环境条件及侵蚀形态类型调查研究,分析了豫西黄河流域控制土壤侵蚀的主要地质环境特征。在此基础上,依据不同地质环境特征及侵蚀形态特征,对区内土壤侵蚀类型进行了划分。

For the Yellow River area in West of Henan,it is one of the areas that the soil erosion is more serious.The serious soil erosion is not only made to deteriorate the soil and ecological environment day and day,but also got the primary cause of the Yellow River sediment and the flooding problems.The article is based on investigation and research of geological environmental conditions of the soil erosion and erosion morphological types,analyzes main geological features of soil erosion in the Yellow River valley in western Henan.According to different characteristics of the geological environment and erosion morphological characteristics,it divides type of soil erosion in the region.
