摘要：沿海地区城市雨水和过境洪水资源丰富，对雨洪资源进行合理利用，可以提高沿海地区水资源可持续利用程度，更好服务于沿海地区发展。本文将沿海地区城市雨洪资源可利用量按生活用水、工业用水、农业用水和生态环境用水进行分配，分别利用水价法计算生活用水效益，利用能值分析法计算工业和农业用水效益，利用生态环境用水效益分摊系数法计算生态环境用水效益，最后以江苏沿海城市连云港市为例进行了雨洪资源利用效益分析。研究成果为我国沿海地区城市雨洪资源利用效益研究提供了新思路
Abstract: Due to the rich resources of urban rainwater and transit flood in coastal areas, rational utilization of rainfall and flood water resources can improve the sustainable utilization of water resources in coastal ar-eas, to better serve the coastal development. In this paper, the available quantity of water rainfall and flood water resources in coastal are distributed to domestic water, industrial water, agricultural water and ecologic environmental water. Water price method is used to calculate domestic water efficiency. Energy synthesis is used to calculate the industrial and agricultural water-use efficiency. Ecologic environmental water-use effi-ciency-sharing coefficient method is used to calculate the ecologic environmental water-use efficiency. Fi-nally, taking Lianyungang City, a Jiangsu coastal city as an example to analyze the rainfall and flood water resources utilization efficiency. The results provide a reference to the research for China’s plain area rainfall and flood water resources benefit analysis.
