In this paper, two ways of utilization of rainwater resources, collection and seepage of rainwater resources, are proposed.Methods for the calculation of utilization amount and benefit quantification in different utilization ways were developed.A case study was conducted in Zhengzhou City .According to the calculation results, the collection volume of rainwater resources is 0.86×10 8 m 3 per year in the city, and the resources can bring a benefit of about 4.74 ×10 8 yuan.The seepage volume is 0.72 ×10 8 m 3 per year, and the volume of supplemental groundwater is 0.11×10 8 m 3 per year, which can produce a benefit of 2.09×10 8 yuan.The results show that the utilization potential of the rainwater resources in Zhengzhou City is tremendous , and it can produce considerable economic and ecological benefits .
