【摘要】：本文属于导师谭少华教授所主持的国家自然科学基金项目《基于步行行为的主动式健康干预的住区环境研究》（批准号：51278503）的子课题研究。在规划建设、国家政策、学科建设等层面上，加强规划科学性已成共识。而步行网络空间量化分析不仅有助于提升规划方法的科学性，更有助于改善步行环境。本研究首先从步行网络、可达性理解以及可达性定量研究三个方面进行了详细的国内外研究综述。然后以小学步行网络为研究对象，从空间阻隔的角度对影响其可达性的因素进行了深入的分析，并以此为基础构建了一个完善的评价体系。具体研究内容分为以下几个方面：第一、在理想状态下即无空间阻隔下，对小学步行网络可达性进行评价；第二、从物理、狭义、广义层层递进对可达性进行了深入的理解，构建广义可达性视角下，包含了社会空间阻隔、城市空间阻隔、自然空间阻隔三大因子的评价体系。第三、收集相关数据，并运用GIS和物质形态定量化分析手段，对南岸区南坪片区小学步行网络进行单因子可达性评价，并在此基础上，运用多因子的叠加分析手段，进行了综合因子的可达性评价；第四、通过实证研究的成果分析，总结影响小学步行网络可达性的空间特征及产生机制。第五、依据上述研究成果，提出改进意见，力图改善小学生上下学的步行网络，，并总结了本阶段研究存在的局限性。
[Abstract]:This paper is a subproject of the National Natural Science Foundation of China sponsored by Professor Tan Shaohua, Research on the Environment of active Health intervention based on Walking behavior (Grant No.: 51278503). In planning construction, national policy, discipline construction and other levels, strengthening the scientific planning has become a consensus. The quantitative analysis of walking cyberspace is not only helpful to improve the science of planning method, but also to improve the walking environment. In this paper, a detailed review of pedestrian networks, reachability understanding and quantitative reachability is presented. Then taking the primary school walking network as the research object, this paper makes a thorough analysis of the factors affecting its accessibility from the angle of spatial barrier, and constructs a perfect evaluation system based on it. The specific research content is divided into the following aspects: first, under the ideal condition, that is, no space barrier, to evaluate the accessibility of the primary school walking network; second, from the physical, narrow sense, the broad layer by layer progressive to the accessibility of in-depth understanding, The evaluation system of social spatial barrier, urban spatial barrier and natural spatial barrier is constructed from the perspective of generalized accessibility. Third, collect the relevant data, and use GIS and material form quantitative analysis means to evaluate the single factor accessibility of the primary school walking network in Nanan Nanping district, and on this basis, use the method of multi-factor superposition analysis. The paper evaluates the reachability of the comprehensive factors. Fourthly, through the analysis of the results of the empirical research, it summarizes the spatial characteristics and production mechanism of the impact on the accessibility of the primary school walking network. Fifthly, according to the above research results, some suggestions are put forward to improve the walking network of primary school students to and from school, and the limitations of this study are summarized.
