Research On The Aging Design Of The Outdoor Environment Of Old Residential Areas Under The Concept Of Healthy Community

In the process of urban renewal,the reconstruction of old residential areas is a hot topic in the academic circle.At the same time,as an important subject in the old community,how to improve the living environment of the elderly through aging design has become an important research issue.The existing relevant aging design studies are mostly aimed at meeting the basic needs of the elderly,and lack of positive transformation to achieve a higher goal-improving the health of the elderly on the basis of meeting the needs.In this paper,the concept of healthy community is introduced into the aging design theory of old residential areas,and the index system of environmental and population health survey is constructed.Five representative old residential areas in the main urban area of Chongqing are selected as the research objects(including four unreformed Daqidong residential areas,Shiyang Street residential areas,Liyuan Village residential areas,Hongyuan residential areas and a reconstructed Shuanggang Road residential area).Using the methods of questionnaire,field investigation and spatial analysis,the outdoor environmental health and population health of the residential area were investigated and analyzed.The results showed that there was a positive correlation between environmental health and population health,and the evaluation of population and environmental health in Shuanggang Road Community was much higher than that in the other four communities.From the analysis of environmental health data alone,Shuanggang Road Community,which has completed the aging transformation,still has a low score in terms of diversity and flexibility in functional health,lighting facilities in perfect facilities,and plant configuration in landscape greening.However,the four old residential areas with low scores generally have activity spaces without considering health and flexibility,poor comfort and lack of space diversity;The supporting public service facilities are dilapidated or lacking,and the design lacks humanization and pertinence;The pedestrian accessibility of traffic space is poor,some types of pedestrian space are unsuitable,and the parking space planning is unreasonable;The landscape ecological empty green space rate and green coverage rate are low,the plant configuration mode is single,the pavement is missing or poor quality,and there is no landscape sketch.In addition,through the analysis of the health data of the population,it is found that the health of the elderly in the old residential areas of Chongqing is declining in terms of physical symptoms and organ functions,positive emotions,cognitive abilities,role activities and social adaptation.The improvement effect of outdoor environment design on its health should be considered in the reconstruction.In view of the above problems,combine with relevant excellent practice cases at home and abroad to seek solutions.From increasing the design of activity space to promote the health of the elderly,increasing the functional complexity and form diversity of activity space,increasing the permeability of space,improving the comfort,strengthening the refined design of supporting public service facilities,using barrier free facilities and diverse traffic combination methods in traffic space,enriching plant configuration,increasing the number of healthy plants,pavement suitable for aging and sketch design,focusing on diversity,close to nature The participatory aspect summarizes the transformation strategy for reference.The representative Daqidong residential area is selected as the reconstruction case,and combined with the design strategy,through the reconstruction design of its activity space,supporting public service facilities,traffic space and landscape ecological space,the practical method is explored.The purpose is to provide theoretical reference for the aging transformation of old residential areas under the concept of healthy community,and also provide more ideas for the healthy aging design of outdoor environment of old residential areas in Chongqing.
