摘要
在全国土壤抗侵蚀特征原位测试的基础上,结合长江中上游地区水土流失的基本问题诸如水土流失的严重性、坡地土壤侵蚀的基本过程、水土流失与江河泥沙的关系等进行了初步论证,指出长江中上游地区水土流失是严重的,但与江河泥沙的关系并不密切。长江中上游地区水土流失有其本身的特殊性,水土保持亦应提倡"排水保土",而不是"水土保持"的观点。
Based on soil erosion tests, this article analyses aspects of the problem of soil and water loss in the Yangtze River basin. These aspects include theories of soil and water loss, the basic course of soil erosion in sloping fields, the relationship between soil and water loss and river sedimentation, the basic theories of soil and water protection. Also, it is highlighted that soil and water loss in Yangtze River basin is serious, but is not strictly related to river sedimentation. The idea to 'drain and protect soil' is put forward in place of the notion to 'protect soil and water'.
