为了研究土地利用变化对设计洪水的影响，采用同频率放大的方法计算设计暴雨，并构建潢川流域的SWAT模型，从而推求出设计洪水。根据计算结果，分析了土地利用方式的改变对淮河上游小流域设计洪水的影响，通过对设计洪峰、洪量及洪水过程的分析表明：流域土地利用变化前后，相同频率下的设计洪量减小，且频率越大，减小越多；不同频率下的设计洪峰均有减小趋势，且频率越大，减小越多。对上述设计洪水变化特征进行分析，设计洪水变化规律明显，表明土地利用变化对流域设计洪水有显著影响。

In order to study the effect of land use change on the design flood,the method of fre-quency amplification is used to calculate the design storm.In this paper,and then the SWAT model of Huangchuan River Basin is built up to derive the design flood.According to the calcu-lated results,this paper analyzes the effect of the change of land use pattern on the design flood of small river basin in the upper reaches of Huaihe River.The analysis of the design flood,flood peak and flood process,indicates that before and after the land use changes in the basin,the same frequency of design flood volume decreases,and the higher the frequencis the more reducing will be.There is a decreasing trend in the case of design flood peaks with different frequencies;and the higher the frequency is,the more the reduction will be.Analysis of the characteristics of the above mentioned design flood shows that,the variation law of design flood is obvious,thereby in-dicating that the change of land use may have a significant effect on the design flood.
