Abstract

In response to the fact that it is not strong of systematic evaluation of rainwater utilization potential, and lack the results of rainwater utilization potential for the whole country and different levels of climate zones, this paper defines and divides suitable rainwater harvesting and utilization areas based on the differences of geography, climate and geological conditions in China, and also describes the rainwater development and utilization potential from the perspective of “appropriate” development and utilization of unconventional water resources and constructs a calculation model to evaluate the rainwater development and utilization potential in China based on geological and climatic dimensions. The results show that China’s rainwater harvesting and utilization area is divided into core area and general area, in which the core area is divided into Loess Plateau hilly area and Karst area. In 2025, China’s potential of rainwater development and utilization is 117.14 billion m³, while the rainwater development and utilization rate is only 0.7%, so there is a large potential and space for development and utilization of rainwater resources in the future, and we can vigorously develop and utilize the rainwater in places where there is demand.
