Study On The Influence Of Physical Environment Perception Of Blocks On Walking Well-being In Main Urban Area Of Harbin

With the development of China's motorized transportation,people rely more and more on various means of transportation,coupled with the special climatic conditions in cold cities,resulting in poor walking emotional experience,which reduces people's willingness to walk outdoors and poses a serious threat to people's physical and mental health.Therefore,improving people's walking emotional experience has become the main task of current urban development.Although the existing research literature shows that the process of the influence of neighborhood environment on walking well-being may be direct or indirect through the leisure activities in the process of walking to affect walking well-being.But most of them only exist in a single study between the two,lack of research on the mechanism of the impact of physical environment on walking well-being.Therefore,this paper chooses seven blocks in the main urban area of Harbin to conduct a survey,using multiple stepwise regression and mediation effect test methods,to study the impact of physical environment on walking well-being,and to explore in depth the impact mechanism of physical environment on walking well-being.Based on the actual situation of Harbin and the existing research results,11 meso-physical environment factors and 13 micro-physical environment factors were selected from both direct and indirect perspectives.Six walking emotional factors were selected from the experience of predecessors.The first step of empirical research is to analyze the effects of different levels of physical environment on walking well-being,different levels of physical environment on walking leisure activities,and walking leisure activities on walking well-being through multiple stepwise regression.The study found that there were significant effects between the three on two levels.Medium-level physical environment factors have a greater impact on walking well-being than micro-level.Individual safety,mixing degree of building functions,accessibility of public transport stations and number of square green space are the most important factors affecting walking well-being.At the micro level,the commercial function along the street,the permeability of the street interface,the continuity of the street interface,the ratio of height to width of buildings and environment,and the greening level have great influence on the well-being of walking.The second step of empirical research is to establish a structural equation model between the three to test the mediating effect of walking leisure activities,and to explore the impact mechanism of physical environment on walking well-being.The study found that walking leisure activities played a mediating role in both levels,and at the micro level was stronger than at the meso level.At the same time,it proved that the physical environment of the neighborhood could indirectly affect walking happiness through walking leisure activities.The accessibility of shelter facilities,road access and daily service facilities had an indirect effect on walking happiness.The impact is greater.Based on the above research,the priority of influencing factors is determined from two perspectives of built old blocks and future new blocks,and the short-term optimization strategy and long-term supplementary strategy for built old blocks are put forward to form a safe and open small plot model,mixed layout of land use function and supporting facilities,continuous and comfortable street space model.The construction mode of newly built pedestrian happy neighborhood with multi-level management and security system as its main part.
