城市雨水利用研究进展与发展趋势

城市雨水利用已成为缓解城市水资源危机和水污染严重的有效途径。在论述城市雨水利用相关理论与技术等研究现状的基础上,对城市雨水利用急待研究的若干问题与发展趋势进行探讨。指出城市降雨产汇流模型的建立与资源化潜力的计算、城市雨水水质监测与管理技术、城市雨水利用规划以及城市雨水利用技术的综合应用等是目前城市雨水利用研究急待解决的热点问题,认为城市雨水利用应用基础研究正在从定性向定量化方向迈进,城市雨水利用技术由单一化向多元化和综合方向发展,城市雨水利用的功能在不断拓展,并将成为城市防洪工作的重要内容与手段之一。

Research advance of urban rainwater utilization

Urban rainwater utilization is an effective way to solve water shortage and water pollution.By summarizing the exiting theories and technologies of rainwater utilization,some important recent problems in this field were put forward.Setting up runoff generation model and calculating the potential of rainwater utilization,monitoring and managing rainwater quality,planning rainwater utilization in urban areas and applying the rainwater utilization technologies comprehensively were problems that should be studied.The fundamental research direction of urban rainwater utilization will be changed from the qualitative to the quantitative,the urban rainwater utilization technologies will be developed from the single to the integrated,and the urban rainwater utilization will become one of important methods for the urban flood control.
