摘要
防洪减灾经济效益涉及面广,内容繁多,且第一手实际资料难以搜集,因而计算复杂。文中建立了沧州市最大15日降雨量与受灾面积关系曲线,采用对比法对沧州市防洪体系的防洪减灾经济效益进行了计算,利用经济效益费用比作为指标,对沧州市的防洪体系进行了评价。
Due to the wide coverage,massive content,and the difficulties in gathering the first hand data,it is complicated in calculating the economic benefit of flood control and natural disaster reduction.This paper builds the ralation curve of the maximum fifteen days＇ rainfall and flooded area,calculates Cangzhou＇s cost-effectiveness in flood control and natural disaster reduction with the contrast method.Taking the economic benefit cost ratio as index, it evaluates the flood control system of Cangzhou.
