Research On The Renovation For The Elderly Of Old Residential Areas Outdoor Environment Based On Post-occupancy Evaluation

Under the background of the aging problem in our country,home-based care has become the main pension mode.The outdoor environment of the old community in the city is the main activity place for the old people’s entertainment and fitness,and it is an important carrier of the home-based care.However,there is still a big gap between the theory and practice of the old community outdoor environment adaptive aging transformation in China.It is of great significance to study the adaptive aging transformation strategy from the perspective of post use evaluation to ensure the smooth progress of the old community adaptive aging transformation and alleviate the social crisis brought by the aging.In this paper,the old community of Wuhan after the aging transformation is taken as the research object,through the construction of a set of post use evaluation method to study the satisfaction of the community outdoor environment transformation,analyze the advantages and disadvantages of the transformation status,and further explore the aging transformation strategy of the old community outdoor environment in Wuhan.This paper consists of six chapters:The first part(Chapter 1 and Chapter 2)is to raise questions and elaborate the relevant theories.This paper expounds the research background,research status at home and abroad,defines the research scope,object and related concepts,determines the research objectives and research framework,and combs and analyzes the relevant theoretical research and case practice,such as post use evaluation,the needs of the elderly group,and the adaptive aging transformation of old communities in Wuhan,so as to lay a theoretical foundation for the follow-up research.The second part(Chapter 3 and Chapter 4)is mainly to build the evaluation system of the old community and summarize the advantages and disadvantages of the old community in Wuhan through case evaluation.The evaluation system of the outdoor environment of the old community in Wuhan is composed of three parts: evaluation index,index weight and scoring method.Firstly,the basic framework of indicators is established according to the policy standards,including 1 objective layer and 4 criteria layers;through literature research,the relevant factors of aging adaptability are selected;combined with questionnaire survey,20 indicators are selected.Then,experts and users are asked to compare the importance of indicators,and a judgment matrix is constructed to determine the weight of indicators.Finally,the user is asked to describe the evaluation indexes according to five levels of very satisfied,satisfied,general,dissatisfied and very dissatisfied by using the Richter scale scoring method.Different levels correspond to 5-1 scores.Through the evaluation of five old communities in Wuhan,it is found that the indicators with higher satisfaction are residential entrance and exit,guide sign,number of activity space,site accessibility,site comfort,landscape interest,landscape identification,accessibility of elderly care service facilities;the indicators with lower satisfaction are pedestrian road,parking,site function zoning,site height difference treatment,rest facilities,night lighting,landscape participation,plant safety,types of pension service facilities.The overall satisfaction scores of the five old communities were: Ganghua 123 community(3.8322)> Dongting community(3.7075)> Ganghua 121 community(3.4650)> Yuanjia community(3.2619)> Renyi community(3.0339).The third part(Chapter 5)puts forward the optimization design strategy for the outdoor environment of the old community in Wuhan.Firstly,three principles should be followed: the principle of using the existing resources of the old community,the principle of full-age application,and the principle of hierarchical transformation.Secondly,on the one hand,the road traffic reconstruction should strengthen the motor vehicle parking reconstruction to solve the problem of insufficient parking spaces and lack of accessible parking,on the other hand,it should strengthen the pedestrian road accessibility reconstruction to ensure the walking safety of the elderly residents in the community;the site space reconstruction should focus on building multi-level compound site and barrier free reconstruction to meet the needs of the elderly In order to improve the safety of outdoor activities,we need to improve the participation of landscape to meet the gardening and planting needs of the elderly,on the other hand,we need to strengthen the safety of plants to promote the health of the elderly.In addition,we need to improve the types of facilities from three aspects of life,medical treatment and entertainment,and propose to embed new facilities and integrate resources and function replacement.Finally,taking the example of Ganghua 121 community,a series of achievements from the evaluation system to the transformation strategy are proved to be feasible in the actual transformation of a single community.
