基于SCS模型的西安市主城区雨水资源化利用分析
Analysis on Rainwater Resources Utilization in Main Urban Area of Xi'an City based on SCS Model
摘要
Abstract
As an unconventional water resource that can be collected and utilized,rainwater can alleviate the problems of urban waterlog-ging and water shortage.Through the comprehensive analysis of rainfall data from 1932 to 2020,combined with the SCS model constructed by land use,soil type and DEM data,the rainwater resource potential of the main urban area of Xi'an under different rainfall frequencies is estimated,the water demand of potential rainwater users is analyzed,and the rainwater utilization benefits are quantified.The results show that:The rainwater resources potential of different design level years is 91～209 million m3;the potential demand for rainwater is 82.379 million m3;the benefit of different design level years is 421～571 million yuan.It is suggested that the construction of sunken green space,permeable pavement,ecological retention pool and green roof should be adopted in the areas of permeable ground,water sys-tem,roads,buildings and communities.Combined with the policy system issued by Xi'an Municipal Government,rainwater resources should be rationally utilized to promote the future development of Xi'an City.关键词
