降雨径流导致的水体流失,会将地面当中含有的碳化合物和处于溶解状态的氮连同泥沙等物质一起冲刷走,不仅会降低地表原有的肥力,更能够让附近的受纳水体收到程度不同的污染。不同的地区存在着不同的治理标准,其当前的治理程度也存在差异,因此在判断降雨径流对水土流失的影响方面也存在难度。本文为了为其它的小流域的水土流失治理提供可借鉴的依据,分析和探讨了不同程度的小流域治理对降低径流拦蓄泥沙的效益和功用,同时结合了某省的小流域A和小流域B的对比实例,测验并研究了不同程度治理情况下的降雨径流泥沙问题,希望能够为有关人士和单位提供有益的参考。
Water loss due to rainfall runoff scouring carbon compounds contained in the ground and dissolved nitrogen along with sediment and other substances will not only reduce the original fertility of the surface but also enable the nearby receiving water body to receive the degree Different pollution. There are different standards of governance in different regions and their current degree of governance varies. Therefore, it is also difficult to judge the impact of rainfall runoff on soil erosion. In order to provide reference for other small watersheds to control soil and water loss, this paper analyzes and discusses the benefits and functions of different watersheds in reducing runoff and sediment deposition. At the same time, combining the small watershed A and the small watershed B comparative examples to test and study the different levels of treatment of rainfall runoff and sediment problems, hoping to provide useful reference for the parties and units.
