Abstract

In terms of alternative rainwater resource utilization, the utilization of urban rainwater resources is very important. This paper summarizes the history, current situation, and utilization pattern of rainwater resources utilization in Qingyang, a typical city in the Loess Plateau. And on this basis, the main problems of urban rainwater resource utilization are analyzed and a method is proposed to evaluate the potential of urban rainwater resource development and utilization. According to this evaluation, if the precipitation guarantee rate is 50%, the potential of rainwater resource utilization in Qingyang City is 18.72 million m3, while the current utilization of urban rainwater resources only accounts for 12.6% of the total amount available, leaving a large potential for the utilization of rainwater resources in the city. This paper also suggests that groundwater replenishment is the top priority for the sustainable development and utilization of urban rainwater resources in Qingyang.
