摘要
可能最大暴雨(PMP)是研究内陆地区尤其山区流域可能最大洪水(PMF)的必要前提,是水电工程选址中的重要因素之一。以汀江流域为例,在分析研究区域内典型暴雨特性的基础上,分别采用当地模式、移植模式、组合模式估算了研究流域面平均的可能最大暴雨(PMP),并将估算结果与邻近的、相似集雨面积流域的可能最大暴雨(PMP)结果相比较,从极大性与合理性方面验证了分析方法的可行性以及本次估算结果的可靠性,为相似流域的可能最大暴雨(PMP)估算提供参考依据。
Probable maximum precipitation（PMP）is not only a prerequisite to estimate probable maximum flood,but also an important factor in determining hydropower project sites.Taking the Tingjiang River as an example,based on the character analysis of typical storm of this region,this paper adopts the local storm method,the storm transplantation method and the storm combination method to estimate average areal probable maximum precipitation of Tingjiang River and the results are compared with other PMP values in similar river basins nearby to validate their rationality,which is useful for PMP analysis of other similar watersheds.
