摘　　要：为进一步研究资料短缺流域设计洪水推求这一工程水文分析计算领域的难题,探索新的可行方法和途径,收集整理了江西省117个水文测站的年最大洪峰流量序列。基于指标洪水法进行了区域性洪水频率分析,推求了江西省九个水文分区的区域性洪水频率综合增长曲线。结果表明:与单站设计洪水成果相比,指标洪水法计算的区域性洪水频率设计成果总体较好,可作为常规的水文比拟法、地区综合法等方法的重要补充。研究成果可为中国中小流域设计洪水推求提供参考依据。The design flood analysis and calculation for the river basin with insufficient data is still an unsolved puzzle in the field of engineering hydrology.For exploring new feasible methods to improve the deficiencies of the current methods,this paper attempt to analyze the regional flood frequency based on the index flood method by using the maximum peak discharge sequence of 117 hydrological stations in Jiangxi provinces.The comprehensive growth curves of the regional flood frequency of 9 hydrological sub-regions in Jiangxi Province are derived.The results show that compared with the design flood results of a single station by using traditional method,the design results of the regional flood frequency calculated by the index flood method generally have good applicability.It can be used as an important supplement to the conventional hydrological analogy method and the regional comprehensive method.The research provides new methods and important reference basis for the design flood inference in small and medium-sized river basins.
