Research On The Application Of Improved AHP - GIS Model In The Location Of Pension Land

As the elderly population is increasing year by year, aging is becoming increasingly serious, our country has entered the aging society. Correspondingly, the elderly consumer groups and service demand gap is increasing, the development and evolution of more and more scholars focus on the pension industry. In the mode of economic development and rational allocation of resources in urgent need of transformation, the supply side structural reform of the environment, faces enormous pressure to the inventory, the real estate industry reform is imminent, it will make the social forces pension services industry to become the protagonist, more and more social capital is invested in the investment and development in the field of pension industry. The recent researches related to the pension real estate are generally focused on the development of pension project. However, those researches are all with the lack of the "Internet plus" industry and intelligent pension industry which are under a fresh and new perspective. It is known that Beijing-Tianjin-Hebei are in an urban pattern integration strategy, but all those former researches are within the strong guidance and cannot serve for this integration strategy. On one hand, people all with the internet think, on the other hand, the concept of wisdom endowment is deeply rooted among people. Under such a condition,it is need to rearrange the sustainable development of real estate industry of our country endowment from a new perspective. In this way, it is possible find a way to solve the problem of aging society under the old endowment.In this paper, the innovative integrated algorithm based on analytic hierarchy process(AHP) and geographic information system as the theoretical basis, to build affordable pension site selection model of real estate. Take Jinnan District in Tianjin as an example, to find a suitable building affordable endowment real estate area of land, First of all, using the Delphi law to establish the evaluation index system, then use the AHP(The Analytic Hierarchy Process, The AHP) to determine the elderly pension service demand of the influence factors of site selection, and then determine the criterion index weight, calculate the grey weight with grey model, the combination of Arc and GIS spatial analysis methods, the establishment of influencing factors the location of the pension estate security index by spatial analysis, buffer analysis, conversion of raster data and vector data between the operation and the weighted superposition analysis of spatial analysis tools that are suitable for the construction to ensure the best location of the pension real estate.
