摘　　要：受地形地质条件的影响,短历时强降雨容易给山区小流域带来突发性洪水。选取广西暴雨中心区之一的贝江流域,以其支流培秀河为研究对象,以融水县培秀河培秀水文实验站为例,采用培秀水文实验站建成后的雨量、水位、流量等实测资料,对培秀河小流域“暴雨-产流-汇流”进行研究,分析南方山区小流域内产汇流特性的变化规律,通过多元回归、降雨-径流等方法构建小流域洪水预警方案,为贝江流域的“暴雨-产流-汇流-演进”及洪水预警奠定基础。Due to the impact of topographical and geological conditions,short duration heavy rainfall is easy to bring sudden flood to small river basins in mountainous areas.Beijiang River basin is one of the rainstorm center areas of Guangxi.Peixiu Hydrological Experiment Station in Rongshui County is located on Peixiu River,a tributary of Beiji⁃ang River.Based on the precipitation,water level and flow measuring data of Peixiu Station,the authors studied the rainstorm,runoff generation and confluence in small Peixiu River basin,analyzed the change law of runoff genera⁃tion and confluence characteristics of small river basins in southern mountain areas,drafted a small river basin flood warning scheme by methods of multiple regression and rainfall-runoff,which laid a foundation for the rainstorm runoff generation-confluence-evolution and flood warning in Beijiang River basin.
