In recent years, under the influence of multiple factors such as traditional ideas and living economic conditions, the aging population in China continues to increase. Most of the elderly are more inclined to aged at home, and the first places for elderly activities are communities and the surrounding environment, which greatly affects the convenience of life and happiness of the elderly. In this paper, Changxindian area in Fengtai District of Beijing was as the research object, and detailed calculation and analysis were carried out by using POI data and arcGIS software. The relative location of residential areas and surrounding public toilets was explored, and the best location of public toilets in the daily walking area under the model of community home-based care for the elderly was further studied.

With the increasing number of western peregrinators to China, the number of travellers to Beijing and the Great Wall continued to increase, forming the north China peregrination route. This paper analyzed the concrete impression of western peregrinators on Beijing and the Great Wall, and held that the structural characteristics of western peregrinators were caused by the change of trade requirements.

Based on the data of residential buildings and office buildings in the built-up area of Beijing, using quantitative analysis tools such as correlation analysis, ArcGIS kernel density analysis and cluster analysis, this paper discussed the spatial agglomeration characteristics of office areas and residential areas around the rail transit station from the two levels of micro structure and macro distribution. The results showed that: (1) The spatial agglomeration of offices and residences around the rail transit station had an obvious concentric ring structure, and such concentric ring structure was most obvious in the transfer area of rail transit from 5 km to 10 km from the city center. (2) Both the residential space and office space presented distinct spatial differences and multi-center agglomeration characteristics. The office space was mainly distributed between the East Third Ring Road and West Third Ring Road as well as the South Second Ring Road to the North Fifth Ring Road, and agglomerated in the China World Tower, the Beijing Financial Street and Zhongguancun, while the residential space was spread from the center of the city to the surrounding area. (3) From the perspective of jobs-housing balance, the areas of jobs-housing balance were mainly distributed within the fourth ring of northern Beijing, while the peripheral areas and southern Beijing were mainly residential functions, and the impact of Beijing rail transit on urban spatial structure was still in its infancy.
