【摘要】：十八大报告首次提出建设“生态文明”理念,将生态问题上升到“五位一体”的战略高度。生态问题中的城市节水工作引起了党中央、国务院的高度重视。为建设自然积存、自然渗透、自然净化的自然生态城市,2014年住房与城乡建设部提出海绵城市建设理念并组织编制了《海绵城市建设技术指南》。海绵城市的思想是对传统开发建设思维的一种全新的转变,从过去的形式构图,营造视觉优美的绿地景观设计转换到一种结合生态、绿色基础设施的设计,建设可持续发展城市为目标。黄土高原河谷沟壑地区是我国人居环境开发最早的地区之一,同时也是我国水土流失最为严重、生态最为脆弱的地区,延安市就是该地区具有典型代表的城市:一方面她面临着缺水、干旱的长期困扰,另一方面又面临着洪水、内涝灾害的严重威胁。如何使城市像海绵一样将水体有效吸纳、缓释、滞留,成为解决这个问题的关键所在。而城市绿色开敞空间的建设从一定程度上可以实现这个愿景。黄土山地城市海绵城市营造的重点在于城市绿色开敞空间,绿色开敞空间是城市众多系统中的重要组成部分,具有重要的自然生态功能和社会文化功能,是自然生态环境与城市人工环境的交融地,是改善城市空间结构和功能的调节器,也是促使城市可持续发展的空间载体之一。论文在对绿色开敞空间、上山建城、海绵城市基本理论、方法、相关研究和实践总结的基础上,首先对绿色开敞空间在海绵城市建构中的作用进行了研究,分析绿色开敞空间对海绵机能,生态格局等方面作用并探究海绵城市对传统绿色开敞空间的布局影响。其次,对延安地区地质、地貌、水文、气候、生态植被等条件进行研究,对影响延安山地新区绿色开敞空间相关要素特征进行了归纳,分析延安新区营建海绵城市的应对方式。最终,在此基础上提出了基于海绵城市理论视角下的延安新区绿色开敞空间的建构方法和规划布局方案,并提出适宜黄土高原山地城市的海绵城市营建模式。
[Abstract]:The 18 report first put forward the idea of building "ecological civilization" and raised the ecological problem to the strategic height of "five in one". The urban water-saving work in ecological problems has aroused the great attention of the Party Central Committee and the State Council. Natural infiltration, In 2014, the Ministry of Housing and Urban-Rural Construction put forward the concept of sponge city construction and organized the compilation of "sponge city construction technical guide". The idea of sponge city is a new change to the traditional thinking of development and construction. From the past form of composition, to create a visually beautiful green landscape design to a combination of ecological, green infrastructure design, The gully region of the valley of the Loess Plateau is one of the earliest areas of human settlement environment development in China, and it is also the region with the most serious soil and water loss and the most fragile ecology. Yan'an is a typical city in this area: on the one hand, it faces water shortage and drought, on the other hand, it faces the serious threat of flood and waterlogging. Slow release and retention become the key to solve this problem. To some extent, the construction of urban green open space can realize this vision. Green open space is an important part of many urban systems. It has important natural ecological function and social cultural function. It is the blending place of natural ecological environment and urban artificial environment, and it is the regulator to improve the urban spatial structure and function. It is also one of the space carriers to promote the sustainable development of the city. Based on the basic theories, methods, relevant research and practice summary of green open space, mountain building, sponge city, Firstly, the paper studies the role of green open space in the construction of sponge city, analyzes the effect of green open space on sponge function and ecological pattern, and probes into the influence of sponge city on the layout of traditional green open space. This paper studies the geological, geomorphological, hydrological, climatic and ecological vegetation conditions in Yan'an area, summarizes the characteristics of the related elements affecting the green open space in the new area of Yanan mountainous area, and analyzes the coping methods for the construction of sponge city in Yan'an new area. On the basis of this, the construction method and layout plan of green open space in Yan'an New area based on sponge city theory are put forward, and the construction mode of sponge city is put forward, which is suitable for mountainous cities on the Loess Plateau.
