摘　　要：以拦沙坝式山溪取水工程为例,对黔中高原小流域雨洪资源的有效利用进行了试验研究。结果表明,试验小流域大雨和暴雨发生频率高,雨洪资源利用潜力大,暴雨洪水过程具有陡涨缓落特征,能够维持较长的引水时间,有利于雨洪资源的有效利用。An experimental study is made on the effective utilization of rain-flood resources in a small watershed in Mid-Guizhou Plateau by taking the debris barrier typed mountain stream diversion works as the study case.The result shows that the occurring frequencies of heavy rain and rainstorm are high in the experimental watershed with large potential of utilizing rain-flood resources,while the rainstorm flood process has the feature of sharp rise and slow fall-down and then can sustain a longer time for water diversion,thus it is favorable for the effective utilization of the rain-flood resources.
