【摘要】：海绵城市的建立,是从解决城市雨涝问题出发,完善城市雨水管理体系,涵养地下水资源,形成良性水循环,最大程度的修复生态环境。作为海绵城市的实体单元——雨水花园,承载着控制雨洪和优化生态、促进水净化循环等主要任务。雨水花园主要由下凹式绿地组成,通过沙土和植物的作用对水源进行处理回收,是一种人工生态可持续的雨水利用和雨洪控制设施,其本身具有恢复绿色生态效益、组建良好景观、解决城市内涝和净化水源等功能。而如何有效地依据低影响开发的理念,通过对雨水花园景观的设计最大化达到预期效益等问题具有重要的理论与现实意义。本文首先梳理海绵城市低影响开发的基本内容和国内外研究现状相关理论,提出论文的研究内容、方法、创新点。其次,从海绵城市和雨水花园概念出发,分析海绵城市理念与雨水花园的关系,对海绵城市构建途径及其影响下的雨水花园设计目标和要求进行了分析。再次,探究海绵城市理念下雨水花园景观设计要素,以及影响其未来雨水花园景观设计的主要因素,包括视觉审美、社会功能、环境状况三个方面,为海绵城市理念雨水花园景观设计的评价指标体系的构建奠定基础。最后,结合上海后滩公园和金华市燕尾洲公园两个案例,建立指标和评语集,运用模糊综合评价法,构建海绵城市雨水花园景观设计的模型,采用专家打分制和计算权重,针对案例结果判断低影响开发下雨水花园对控制雨洪和净化节约水资源等具有明显的效果,研究结果表明:两大公园的评价结果与实际相符,证明基于模糊综合评价的海绵城市理念下雨水花园景观设计评价方法科学可行,通过该模型分析,就雨水花园来看,上海后滩公园设计总体上优于金华燕尾洲公园,并根据结果具体分析优缺点,提出建议,为低影响开发理念下雨水花园的景观设计提供一条定量的依据。
[Abstract]:The establishment of sponge city is to solve the problem of urban rain and waterlogging, perfect the management system of urban Rain Water, conserving groundwater resources, form a benign water cycle, and restore the ecological environment to the greatest extent. Rain Water Garden is mainly composed of concave green space, which uses sand, soil and plants to treat and recover the water source. Rain Water is a kind of artificial ecological sustainable utilization and rain flood control facility, which has the functions of restoring green ecological benefit, constructing good landscape, solving urban waterlogging and purifying water source, and how to effectively base on the concept of low impact development. It is of great theoretical and practical significance to maximize the design of Rain Water garden landscape and achieve the expected benefits. Firstly, this paper combs the basic contents of the low impact development of sponge city and the relevant theories of domestic and foreign research status. Secondly, from the concept of sponge city and Rain Water garden, the relationship between the concept of sponge city and Rain Water garden is analyzed. This paper analyzes the way of construction of sponge city and the design objectives and requirements of Rain Water garden under the influence of sponge city. Thirdly, it probes into the elements of landscape design of rainy water garden in sponge city, and the main factors that affect the landscape design of the garden in the future. Including three aspects of visual aesthetics, social function and environmental condition, which lay the foundation for the construction of evaluation index system of Rain Water garden landscape design. Finally, combined with Shanghai Houtan Park and Jinhua Yanwei Zhou Park, two cases, Set up index and comment set, use fuzzy comprehensive evaluation method, construct the model of Rain Water garden landscape design in sponge city, adopt expert scoring system and calculate weight, According to the result of case study, it is concluded that the development of rain water garden with low influence has obvious effect on controlling rain flood and purifying and saving water resources. The results of the study show that the evaluation results of the two parks are in accordance with the actual situation. It is proved that the evaluation method of landscape design of rainy water garden based on fuzzy comprehensive evaluation is scientific and feasible. According to the analysis of this model, the design of Shanghai Houtan Park is better than that of Jinhua Yanwei Island Park on the whole, as far as Rain Water Garden is concerned, According to the results, the advantages and disadvantages are analyzed, and some suggestions are put forward to provide a quantitative basis for the landscape design of rain water garden with low impact development idea.
