| 摘 要： | 以黄土丘陵区桥沟小流域为研究对象,利用该流域不同地貌部位的野外径流场及沟道水文站网观测资料,探讨了小流域次暴雨泥沙输移比的时空变化特征。依据相关分析法,确定了影响桥沟流域次降雨泥沙输移比的主导因素。结果表明,径流侵蚀力、泥沙相对重率、降雨特性、土壤前期含水量是影响桥沟流域次降雨泥沙输移比的主导因子。采用统计回归方法,建立了黄土丘陵区桥沟流域次降雨泥沙输移比模型。 |

| Abstract: | Qiaogou watershed,located in the hilly-gullied loess region,was chosen as the study area.Based on the observed data from the natural runoff plots and hydrological stations built on different landscape positions,the temporal and spatial characteristics of sediment delivery ratios(SDR) under single rainfall events were discussed.The dominant factors affecting the SDR were determined by correlation analysis.The results show that the antecedent soil moisture content,rainfall characteristics,runoff erosivity pow... |
| Keywords: | sediment delivery ratio single rainfall runoff erosivity power hilly-gullied loess region |
