City Park Accessibility Research Based On Recreational Features Of The Elderly In Changsha

Population aging is an inevitable law of the development of human society, but also an important feature of the twenty-first Century. According to the United Nations is expected in 2015, the world every 4 elderly people will have 1 lives in china. China’s population age structure shows the rapid aging characteristics, the quality of life of the elderly has become the focus of attention of the whole society. Urban park is to play the main body of urban recreational function, has an important significance for the elderly rich the cultural life of the city and to guide the elderly people to form a healthy lifestyle. The elderly image and behavior characteristics as the breakthrough point, to build a multi-agent model to evaluate the city park of Changsha City, has the guiding sense to the city park layout optimization under the background of aging society.Based on this, in this paper, the use of related theories and methods of behavioral geography, the elderly in Changsha City Recreation image with the behavioral data obtained through cognitive map method, questionnaire survey and interview method, elderly recreational features and park to explore the rules of selection, construction of recreational activities of the elderly more wisdom body model to evaluate the accessibility of parks of Changsha City; and finally puts forward suggestions on Changsha City Park accessibility optimization under the background of aging.The main conclusions of this study are as follows:(1) elderly recreation characteristic analysis of survey data, aged people in Changsha City Recreation image presents simple spatial structure with two hot spots in the park, six hot Park and multiple fuzzy park; recreation travel mainly concentrated within the range of 10 km, spatially concentrated recreation circle (D≤1km), low concentration (1km<D≤5km) and recreation dispersed recreation circle (5km<D≤10km) layer model.(2)The multi-agent system simulation results show that Changsha city park accessibility is generally low and the spatial distribution is uneven. With Xiangjiang as the boundary, the east than the West Park accessibility; The five one Avenue line, park accessibility decreasing from five one avenue to the north and south sides; Center Park accessibility is higher, and the edge area park accessibility is lower. In addition, the accessibility of image and behavior to show the difference characteristic.(3) On the basis of Changsha City Park reach of analysis on the evaluation results of the proposed five points for the older age groups the accessibility of parks in optimization suggestions:supply and drainage measures to alleviate the pressure in the center region, optimization of bus lines reduce mature park travel resistance, pay attention to the characteristic shape enhanced the new park attraction, create a community park atmosphere improve old people sense of belonging, carefully understand the needs of older people strengthen the humanistic care.
