| 摘 要： | 流域径流输沙规律反映区域水土保持与生态环境状况，可指导区域水土流失治理与生态建设。流域径流与输沙受降雨、下垫面因素及流域综合环境要素的影响。在对湖南武水流域径流与泥沙输移影响因子分析的基础上，基于次降雨与对应次径流、次输沙（包括悬移质与推移质）实测资料，建立武水流域次降雨条件下的径流与输沙经验回归模型，可用于流域径流与输沙预测预报。

| Abstract: | Runoff and sediment transport laws may reflect the status of water and soil conservation and ecological environment of the watershed and they can also be used to instruct the soil erosion control and ecological con- struction. The runoff and sediment transport are influenced by the factors of rainfall, ground surface conditions and the integral environment factors of the watershed. The multi-factor regression models of runoff and sediment of the watershed were built for Wushui watershed in Hunan Province under single rainfall by using SPSS software, based on analyzing on the influencing factors on runoff and sediment transport data measured at the experiment plots. The result showed that the models could be applied to predict the runoff and sediment transport of Wushui watershed. |
