【摘要】：近年来,随着海绵城市建设的兴起,低影响开发(LID)理念已经成为城市道路建设的一项重要指导理论。但目前国内LID理念下的城市道路绿地建设仍多从决策者和设计者的角度出发,公众参与性明显不够,对于道路绿地的效益评价研究也相对较少,并往往从单一方面展开。综合评价LID理念下的城市道路绿地效益,能够有效解决这类问题,同时也使得LID理念下的道路绿地规划设计程序更加完善。在提升未来道路绿地建设质量的同时,也逐渐形成更加科学化的建设标准及规范。本文从环境、功能、美学三方面展开对城市道路绿地效益的评价研究,分析了LID理念下的武汉市道路绿地特点及使用者的需求特征,构建LID理念下的武汉市道路绿地效益评价体系。在分析模糊综合评价法适用性的基础上,选取武汉市青山区两类典型道路绿地进行评价实证研究。主要研究内容如下:首先,对城市道路绿地等基本概念进行界定,并阐述LID理念下城市道路绿地效益的内涵。在对现有评价方法进行概述比较的基础上,基于模糊数学理论确定LID理念下武汉市道路绿地效益的综合评价方法。其次,结合LID理念下的武汉市道路绿地规划建设情况,通过文献理论研究初选评价体系指标,并利用问卷调查和专家咨询结果,加权计算完成评价体系指标的优化筛选,构建LID理念下武汉市道路绿地效益评价体系,主要包括环境效益、功能效益、美学效益3大准则层,道路雨水管理、小气候改善等6个指标层和径流量削减效果、径流峰值延迟效果等18个亚指标层。采用层次分析法构建两两比较的判断矩阵,根据专家专业评判确定各评价指标的权重,并分析阐述各层次指标的相对重要程度及其含义说明和赋值方法。最后,以武汉市青山区临江大道和武丰二路道路绿地作为评价对象,运用模糊评价法分别对其进行评价研究。评价结果均为Ⅱ级,较好。说明基于LID理念的武汉市道路绿地建设的公众满意度与接受度较高。总结评价结果和目前存在的问题,提出武汉市道路绿地低影响开发建设优化建议。本研究不仅为LID理念下武汉市道路绿地的评价工作提供了一种新的思路和方法,同时也对LID理念下城市道路绿地的建设提供了指导意义。
[Abstract]:In recent years, with the rise of sponge city construction, The concept of low impact development has become an important guiding theory of urban road construction. However, at present, the construction of urban road green space under the concept of LID in China is still from the perspective of decision makers and designers, and the public participation is obviously insufficient. The research on the evaluation of road green space benefit is also relatively few, and often from a single aspect. Comprehensive evaluation of urban road green space efficiency under the concept of LID, can effectively solve this kind of problems, At the same time, it also makes the road green space planning and design process more perfect under the concept of LID. While improving the quality of road green space construction in the future, it also gradually forms more scientific construction standards and norms. The evaluation of urban road green space benefit is carried out in three aspects of aesthetics, and the characteristics of road green space and the needs of users in Wuhan under the concept of LID are analyzed. On the basis of analyzing the applicability of fuzzy comprehensive evaluation method, two kinds of typical road greenbelts in Qingshan District of Wuhan City are selected for the evaluation empirical research. The main research contents are as follows: first, This paper defines the basic concepts of urban road green space, and expounds the connotation of urban road green space benefit under the concept of LID. On the basis of summarizing and comparing the existing evaluation methods, Based on the fuzzy mathematics theory to determine the comprehensive evaluation method of the road green space benefit of Wuhan under the concept of LID. Secondly, according to the situation of Wuhan road green space planning and construction under the LID concept, the index of primary evaluation system is studied through the literature theory. With the results of questionnaire investigation and expert consultation, the index of evaluation system is optimized and screened by weighted calculation, and the evaluation system of road green space benefit in Wuhan under the concept of LID is constructed, which mainly includes environmental benefit, function benefit and aesthetic benefit. There are 6 index layers such as road Rain Water management, microclimate improvement, runoff reduction effect, runoff peak delay effect and 18 sub-index layers. AHP is used to construct the judgment matrix of comparison. According to the expert professional evaluation, the weight of each evaluation index is determined, and the relative importance of each level index is analyzed and expounded. Taking Linjiang Avenue and Wufeng Road Green Space in Qingshan District of Wuhan City as the evaluation object, the fuzzy evaluation method is used to evaluate and study them respectively. The evaluation results are all of grade 鈪，
