Optimal Aging Evaluation And Optimization Study Of Park Green Space In High-density Urban Areas Beyond Health Vision For Wuhan City

Scientifically plan the "three-dimensional space" of urban production,life and ecology,and properly handle the "three-dimensional relationship" between urban production,life and ecology and urban environmental protection,which is a concrete practice of important discussion.However,facing a series of social problems brought about by the aging of population in high-density urban areas,especially the increasingly scarce public resources,high-density population gathering and dispersing areas and the increasingly urgent aging problem in high-density urban areas,not only reflects the tense state of urban development,but also has an in-depth effect on urban parks,greening,transportation,security,environment,economic development level,governance and renewal,Even directly affect the quality of life of the elderly,but also related to the overall development of the country and the well-being of the people.At present,Wuhan has entered the stage of rapid aging.With the increasing aging phenomenon,how to alleviate the contradiction between park green space and aging in highdensity urban areas? How to solve the health problems of the elderly in high-density urban areas through the landscape aging of park green space? How to meet the special needs of the elderly in high-density urban areas for park green space? How to solve the problems faced by the elderly in green outdoor space through the optimization of green landscape in high-density urban areas? How to improve the living conditions of the elderly in high-density urban areas through the landscape aging of park green space? The ultimate goal of how to improve the health status of the elderly in high-density urban areas through the landscape aging of park green space is how to actively respond to China’s population aging,build a pension,filial piety and respect for the elderly policy system and social environment with the characteristics of high-density urban areas,and strive to improve the quality of life of the elderly.This paper is based on Maslow’s demand theory,environmental psychology,geriatric sociology and human efficacy.Taking the high-density urban parks in Wuhan as the main research object,this paper combines practice with theory by using the method of literature research,system construction,real-time geological survey and empirical analysis.Taking the high-density urban area of Wuhan as an example,this paper discusses the evaluation index and optimal design mode of park green space landscape aging in high-density urban area from the perspective of health.Firstly,it explores the relationship between high-density urban park green space and landscape aging,and summarizes the design principles of places for the elderly according to the physical,psychological and social characteristics and needs of the elderly.Secondly,combined with literature theoretical research,investigation and analysis,expert advice and other methods,this paper constructs an evaluation index system at five levels: safety and reliability,convenience and accessibility,social attribution,aesthetic comfort and formal richness,with a total of 18 specific evaluation indexes.The weight is determined by adopting scientific methods,and the landscape aging from the perspective of regional health is taken as the research object and evaluation basis.Thirdly,the representative comprehensive parks,special parks,roadside green spaces and amusement parks in the high-density urban area of Wuhan are selected to understand and obtain the use evaluation of the public living space of the park participated by the elderly in the research area through PLPS research method.By issuing 600 questionnaires,scoring and analyzing the specific index layer,combining the weighting results with the scoring results of park users,this paper obtains the problem of landscape aging in high-density urban areas of Wuhan from five levels,and comprehensively and objectively evaluates the landscape aging of park green space in Wuhan.The optimization strategies are put forward from five aspects: safety and comfort layer,convenient accessibility layer,social attribution layer,formal structure layer and beautiful and comfortable layer.
