【摘要】：在我国快速城市化过程中,高强度的城市建设活动破坏了城市原有的水文循环,城市雨洪安全面临着威胁。频繁发生的城市内涝灾害成为近年来社会各界关注的焦点问题。依靠“以排为主”的传统排水方式已无法解决当下城市面临的内涝问题。国外一些发达国家也曾面临同样的城市问题,经过长期的探索和发展逐渐形成若干个新型雨洪管理体系并在实践过程中取得了较好的效果。其中,由绿色基础设施发展而来的绿色雨水基础设施是一种新兴的综合管理方式,为解决城市内涝问题创造了新的途径。本文在研究绿色雨水基础设施雨水径流管理作用机制的条件下,以武汉市东湖片区的内涝问题为切入点,运用绿色雨水基础设施的径流管理理念,针对研究区存在内涝问题分尺度提出相应的绿色雨水基础设施优化策略、手法及措施,从理论研究层面为研究区内涝问题的解决提供支持。本研究介绍了国内外绿色雨水基础设施的研究进展,传统雨水基础设施的特点,以及具有代表性的新型雨洪管理体系。对比研究绿色雨水基础设施的雨水径流管理优势,探讨绿色雨水基础设施优化程序及方法内容。以武汉市东湖片区为研究范围,通过基础资料分析、现场调研发现问题和计算机景观指数分析等方式,从宏观到微观,从整体到个体分析研究区内绿色雨水基础设施现存的问题。针对研究区现存问题,从区域布局结构、空间布局手法、场地措施三个层面提出研究区的绿色雨水基础设施优化策略、手法及措施。研究提出通过优化绿色雨水基础设施的方法解决或缓解片区内涝问题。利用景观指数研究科学地分析城市透水下垫面与不透水下垫面的空间格局对系统城市排水压力的影响。通过区域GSI空间布局结构的优化以及总结归纳八种GSI空间布局手法,形成由“点、线、面”构成的从场地尺度到区域尺度的GSI网络结构,缓解研究区内涝问题。针对性的提出居住区、市政道路、商业广场三类典型用地的场地层面GSI优化模式及措施,为同类问题的解决提供参考。
[Abstract]:In the process of rapid urbanization in China, the high intensity of urban construction activities destroy the original hydrological cycle of the city, and the safety of urban rain and flood is threatened. Frequent urban waterlogging disasters have become the focus of attention in recent years. The traditional drainage method based on drainage can not solve the problem of waterlogging in lower cities. Some developed countries have been faced with the same urban problems, after a long period of exploration and development, gradually formed a number of new rain flood management system and achieved good results in the process of practice. Among them, green Rain Water infrastructure developed from green infrastructure is a new comprehensive management mode, which creates a new way to solve the problem of urban waterlogging. In this paper, under the condition of studying the mechanism of runoff management of green Rain Water infrastructure Rain Water, taking the waterlogging problem in Donghu Lake area of Wuhan City as the breakthrough point, using the idea of runoff management of green Rain Water infrastructure, Aiming at the problem of waterlogging in the study area, this paper puts forward the corresponding strategies, techniques and measures for the optimization of green Rain Water infrastructure in order to provide support for the solution of the waterlogging problem in the study area from the theoretical level. This paper introduces the research progress of green Rain Water infrastructure at home and abroad, the characteristics of traditional Rain Water infrastructure, and the representative new rain flood management system. By comparing the advantages of Rain Water runoff management in green Rain Water infrastructure, the optimization procedures and methods of green Rain Water infrastructure are discussed. Taking the East Lake area of Wuhan City as the research scope, through the analysis of basic data, field investigation and finding problems and computer landscape index analysis, from macro to micro, From the whole to the individual analysis area green Rain Water infrastructure existing problems. In view of the existing problems in the study area, this paper puts forward the green Rain Water infrastructure optimization strategy, techniques and measures from three aspects: the regional layout structure, the spatial layout method and the site measures. The method of optimizing green Rain Water infrastructure is proposed to solve or alleviate the waterlogging problem. The influence of the spatial pattern of urban permeable underwater surface and impermeable underlying surface on the drainage pressure of the system city was analyzed scientifically by using the landscape index. By optimizing the regional GSI spatial layout structure and summing up eight GSI spatial layout techniques, the GSI network structure from site scale to regional scale is formed, which is composed of "points, lines and surfaces", and the waterlogging problem in the study area is alleviated. The GSI optimization model and measures of residential area, municipal road and commercial plaza are put forward to provide reference for solving similar problems.
