【摘要】 随着城市化进程的深入,城市河流生态系统面临着雨洪失调、污染严重、生态用水不足、生态系统破坏、功能受限等一系列问题。而人们对河流保护与利用的理念不当是造成这些问题的关键。因此本研究通过引入景观基础设施理念,运用理论演绎、GIS量化分析与实证研究相结合的方法,以重庆肖家河为例系统地探讨了景观基础设施视角下城市河流生态修复设计的框架、策略与实践,以期在解决肖家河生态问题的同时实现它的多元价值,为其他城市河流的生态修复设计提供思路。论文首先梳理了城市河流生态修复的内涵、目标与尺度以及景观基础设施的发展历程、相关概念、空间模式和特征,探讨了景观基础设施理念指导城市河流生态修复设计的可行性、核心内涵与意义。其次论文以重庆肖家河为例从流域、河段双重尺度分析肖家河的概况与存在的问题。接着论文从修复设计目标、修复设计方法与技术路线三个方面出发构建了景观基础设施视角下的城市河流生态修复设计框架。最后结合肖家河的分析,在设计框架指导下进行水文过程分析和生态评估,并提出流域、河段尺度下的修复设计策略。论文主要研究成果如下:①明确景观基础设施理念应用于城市河流生态修复设计的核心与积极意义;②以重庆肖家河为例分析与总结了城市河流存在的问题;③构建景观基础设施视角下的城市河流生态修复设计的框架;④以重庆肖家河为设计实证提出生态修复设计策略。更多还原

【Abstract】 With the deepening of urbanization,urban river ecosystems are facing a series of problems,such as storm and flood imbalance,serious pollution,insufficient ecological water use,ecosystem damage,and limited functions.The improper concept of river protection and utilization is the key to these problems.Therefore,by introducing the concept of landscape infrastructure,using theoretical deduction,GIS quantitative analysis and empirical research,this study systematically discusses the framework,strategy and practice of urban river ecological restoration design from the perspective of landscape infrastructure with Chongqing Xiaojia River as an example.In order to solve the ecological problems of Xiaojia River and realize its multiple values,it provides ideas for the ecological restoration design of other urban rivers.The thesis first sorted out the connotation,goals and scale of urban river ecological restoration,as well as the development process,related concepts,spatial patterns and characteristics of landscape infrastructure,and discussed the feasibility,core connotation and significance of landscape infrastructure concept to guide the urban river ecological restoration design.Secondly,the paper takes the Xiaojia River in Chongqing as an example to analyze the profile and existing problems of Xiaojia River from the dual scales of river basin and river reach.Then the paper constructs the urban river ecological restoration design framework from the perspective of landscape infrastructure from three aspects:restoration design goals,restoration design methods and technical routes.Finally,combined with the analysis of Xiaojia River,the hydrological process analysis and ecological assessment were carried out under the guidance of the design framework,and the restoration design strategy at the river basin and river reach scale was proposed.The main research results of the thesis are as follows:①The core and positive significance of the application of landscape infrastructure concepts to the ecological restoration design of urban rivers;②Taking the Xiaojia River in Chongqing as an example to analyze and summarize the problems existing in urban rivers;③Building a city from the perspective of landscape infrastructure The framework of river ecological restoration design;④The ecological restoration design strategy is proposed based on the empirical design of Chongqing Xiaojia River.更多还原
