| 摘 要： | 以甘肃天水罗玉沟流域为研究区，应用分布式水文模型（SWAT）对该流域的径流、泥沙和水质状况进行模拟研究，并重点探讨了降雨和森林植被变化对水文生态响应的影响。结果表明:降雨因子对径流的影响略大于对泥沙的影响；森林植被具有明显的减水减沙生态水文功能，尤其对泥沙的影响更大于对径流的影响。

| Abstract: | This thesis chooses Luoyugou watershed in Gansu province Tianshui city as the example research area, imitating and studying the runoff, sediment and water quality in the research area with the application of distributed hydrological model SWAT (the Soil and Water Assessment Tool), and stressing on the influence of precipitation and forest vegetation change to ecological hydrology responds. The results show that the precipitation influences more to the runoff than sediment; forest vegetation cover have evidence ecological hydrology function of reducing runoff and sediment, especially influences more to the sediment than runoff. |
