| 摘 要： | 高泉沟流域属于黄土丘陵沟壑区。运用灰色关联与相关系数分析法,分析影响该流域坡面产流产沙的降水特征因子。结果表明对黄土丘陵沟壑区产生径流贡献最大的因子是降雨量;对土壤侵蚀量贡献最大的因子是降雨量半小时雨强复合因子。因此,降雨量的多少是影响本区产流产沙最关键的因素。

| Abstract: | Gaoquangou Valley is a hilly loess area.Gray correlation and correlation coefficient methods are used to analyze the rainfall factors.The results show that rainfall amount contributes most to the runoff,and half-an-hour’s rainfall intensity composite factor contributes most to the soil erosion amount. |

| Keywords: | Gaoquangou Valley rainfall factor soil erosion |
