摘要
采用分布式侵蚀产沙模型,以陕西省黑草河小流域为例,对多种水土保持措施和不同土地利用方式条件下流域的径流输沙过程进行数值模拟计算,并通过对比评价了不同水土保持措施和土地利用方式的减水减沙效益,为流域内配置水土保持措施和优化流域管理提供了科学依据和技术支撑。
A distributed model of soil erosion and sediment yield is applied to the numerical simulation made on the process of runoff and sediment transportation for different soil and water conservation measures under various land-use conditions by taking Heicaohe Watershed in Shannxi Province as the study case, and then the benefits from reduction of sediment and runoff for different soil and water conservation measures under various land-use conditions are evaluated through the relevant comparison; which can provide scientific basis and technical support for making the soil and water conservation measures and optimizing the management of the watersheds concerned.
