摘　　要：以连江流域中小河流(200~3000 km^(2))实测洪水资料为基础,无资料地区由设计暴雨推求设计洪水,统筹考虑上下游、干支流和下垫面条件等因素,并结合历史洪水调查资料、已有工程规划和设计洪水成果、基础地理信息数据等,绘制连江流域中小河流不同重现期下洪峰模数等值线图,探索洪峰模数分布规律。结果表明:连江中下游的乳源南部、英德西北部、阳山南部、连南中部和南部等区域洪峰模数较大,防御洪水过程中应当加以重视。本次研究成果可为防御连江流域中小河流洪水提供参考和决策依据,对连江流域水文分析计算、水利水电工程规划与设计具有一定的参考意义。Based on measured flood data of small and medium-sized rivers(200~3000km 2)in the Lianjiang River Basin,The design flood is calculated from the design rainstorm in the area without data.Taking into account factors such as upstream and downstream,main and tributaries,and underlying surface conditions,and combining historical flood survey data,existing engineering design flood results,basic geographic information data,draw contour maps of flood peak flow modulus for small and medium-sized rivers in the Lianjiang Basin at different recurrence periods,and explore the distribution law of flood peak modulus.The results indicate that the flood peak modulus in the southern part of Ruyuan,the northwestern part of Yingde,the southern part of Yangshan,the central and southern parts of Liannan in the middle and lower reaches of Lianjiang River is relatively large,and attention should be paid to flood prevention process.The research results of this study can provide reference and decision-making basis for preventing floods in small and medium-sized rivers in the Lianjiang River Basin,and have certain reference significance for hydrological analysis and calculation,water conservancy and hydropower engineering planning and design in the Lianjiang River Basin.
