Strategic Research on Urban Stormwater Resource Utilization in the Resource Water Shortage Cities - Base on Stormwater Data of 58 Resource Water Shortage Cities

Based on the resource water shortage cities as the research object in this paper, we use the factor analysis method to evaluate the degree of water shortage in the resource water shortage cities, while these factors include the unit of GDP water consumption, the unit of industrial output water consumption, per capita water resource, the city population, per capita domestic water consumption and the average annual rainfall. We also take Tianjin, which is most seriously lacking water resource, as a case study, and the case reveals the importance of urban stormwater utilization in the resource water shortage cities. Finally, we propose some strategic measures to utilize urban stormwater resource in the resource water shortage cities.
