Beijing has entered the stage of accelerated development of population aging. Timely understanding of the distribution of elderly population and spatial layout of elderly service facilities is conducive to accurate and scientific policies. Through Arc GIS spatial analysis technology，this paper presents the spatial representation of the elderly population and elderly care service facilities，and finds that the elderly population and elderly care service facilities in Beijing are characterized by obvious “central agglomeration”，and the aging degree of the population is stratified. At the same time，the population prediction software PADIS-INT was used to predict the elderly population，and the number of beds in nursing institutions，land used for nursing services，and beds in medical and health institutions were predicted.
