The work aims to enhance the pleasantness and comfort of the rehabilitative landscape in modern elderly care institutions. With four elderly care institutions in Nanjing as the research objects, the outdoor rehabilitative landscape evaluation index system for elderly care institutions is constructed based on AHP from six evaluation objectives and 26 evaluation factors of outdoor environment, soft landscape, road environment, facilities, rehabilitation activities and maintenance.

According to the results, the comprehensive scores of the four elderly care institutions in Nanjing rank from high to low as Yi He Nursing Home (4.02), Tai Le Cheng Nursing Home (3.64), Yi Ju Nursing Home (3.55) and Jing Se Yang Guang Nursing Home (3.18) and landscape optimization suggestions are proposed for Yi Ju Nursing Home according to the evaluation factors.
