摘要
雨水是一种重要的水资源,收集利用雨水既可以缓解目前城市水资源紧缺的局面,又是解决城市雨水问题的有效途径。城市公园是城市建设的主要内容之一,是城市景观和城市生态系统的重要组成部分。国内外大量文献表明,城市公园具有雨水管理、净化和再利用等多重功能,是雨水资源可持续利用的中流砥柱。以城市公园内的基本要素作为切入点,对近年来城市公园雨水利用技术的研究进展作了阐述,从雨水利用技术结合铺装、绿地、水景和建筑4个方面进行逐个分析。总结得出各项技术的可行条件及优缺点,并针对目前城市公园关于雨水利用技术的建设的不合理、管理的不完善和后期维护不全面等问题进行讨论,同时展望未来城市公园雨水利用技术研究趋势必将从定性研究转变为定量研究,并且雨水利用技术不再单一使用,而是多种技术综合运用来达到城市公园雨水收集最大化。研究以期为今后城市公园雨水利用的理论与实践提供一定的参考。
Rainwater is one of the important water resources. Collecting and utilizing rainwater can not only alleviate the shortage of urban water resources, but also be an effective way to solve the urban rainwater problems. Urban park is one of the main parts of urban construction, and it is also an important component of urban landscape and urban ecological system. A large number of domestic and foreign documents show that urban parks have multiple functions, such as managing rainwater, purifying rainwater and recycling rainwater.Urban park plays an important role in the sustainable utilization of water resources. The paper takes the basic elements of urban park as a starting point, and expounds the research progress of rainwater utilization technology in urban parks in recent years. The rainwater utilization technologies combined with pavement,green space, waterscape and buildings in urban parks are analyzed one by one. Through analysis, the feasibility and advantages and disadvantages of each technology are summarized. The paper discusses the irrational construction, imperfect management and incomplete maintenance of rainwater utilization technology in urban parks, and proposed that the future research direction of rainwater utilization technology in urban park will be transformed into quantitative research from qualitative research, in addition, the rainwater utilization technology is no longer a single use, but an integrated application to achieve the maximum collection of rainwater. The research can provide some references for rainwater utilization theory and practice in urban parks in the future.
