Research On The Distribution Of The Aged Population And The Optimization Of The Aged Institutions Lanzhou City

Population aging is a major issue facing human society in the 21 st century,and it is also the basic national conditions of China.By 2018,China’s elderly population had reached 249 million,accounting for 17.9 percent of the total population.In recent years,the proportion of the elderly population in Lanzhou has also been on the rise,and the aging population with household registration has become increasingly prominent.By the end of 2018,the elderly population in Lanzhou had reached 714,800,accounting for 21.76% of the total population,which is far higher than the national and provincial average level of aging.Due to the aging of the population,the development of economic development,social development,the development of medical and health undertakings,especially the elderly service system construction will have a far-reaching impact and challenges.This article tried to use the method combining the qualitative analysis with quantitative analysis,in the elderly population in Lanzhou city and endowment facilities spatial distribution based on the analysis of the status quo,using the theory of space analysis and the method to evaluate endowment facilities accessibility,explore the elderly population distribution and the deficiency of existing pension facilities space configuration,combined with the land use data such as Suggestions to optimize the spatial configuration,for Lanzhou city endowment facilities construction and optimize the development decision-making reference.Preliminary conclusions are drawn as follows:(1)The aging population in Lanzhou city has obvious characteristics,and the spatial distribution of the elderly population has the characteristics of circle,which gradually decreases from the central area of the city.The central area of the central area is the high density center of the elderly population,and the vast area outside the central area is the low density area of the elderly population.By the end of2018,83.6 percent of township streets had an aging population of more than 10 percent,and 38.8 percent had an aging population of more than 14 percent,far exceeding the 7 percent threshold for an aging society.(2)The distribution of old-age care institutions in Lanzhou city is extremelyuneven,presenting the characteristics of central agglomeration and peripheral absence.Half of the old-age care institutions and beds are located in Chengguan district,and more than 70% of the villages and towns have no old-age care institutions.In the central region,the elderly care institutions with small scale and large number of individuals are distributed;The large scale endowment structures are mainly distributed in the surrounding areas near the edge of the central zone.The proportion of beds for the elderly is far below the national average,and the service capacity needs to be improved.(3)The availability of service resources in Lanzhou urban pension institutions gradually decreases from the central city to the outer suburbs,and the overall characteristics of "circular distribution and significant differentiation" are presented.The streets with high availability of service resources of pension institutions are located in the middle and eastern part of the central urban area,while the availability of service resources of pension institutions in the western and southern parts of the urban area is relatively weak.The layout characteristics of centralized pension institutions make the proximity of pension institutions,medical facilities and parks have similar characteristics,and the proximity degree of the central urban areas is the highest.(4)According to the principle of conforming to the conditions of transportation,terrain and construction requisition,all the existing pension institutions,except Baitashan apartment for the elderly and Banshan nursing home,all meet the screening conditions.On the basis of the above conditions and considering the influence of medical institutions and the service scope of green space and park on the layout of pension institutions,we finally get 12 candidate points that can be recommended as the priority for the construction of pension institutions.
