The importance of campus mental health work is increasing daily. Warm corridors and green spaces are the main places for students to engage in extracurricular activities on cold campuses. Balancing transportation, activity, and healing functions during planning and construction is necessary. The research on the interaction between cold campuses and green spaces, under the guidance of healing, aims to provide a campus environment that can alleviate stress, relieve tension, and restore physical and mental health, providing decision-making guidance and implementation ideas for campus planning. It is a case study of the campus planning of Harbin Institute of Technology. It uses methods such as a questionnaire survey to extract the functional requirements of warm corridors on cold campuses, the intention type of the campus leisure activity space, and the combination mode of the warm and green spaces. Warm corridors and green spaces are two systems of campus planning for interactive design under the guidance of healing. It proposes an interactive mode of network layout between warm corridors and green spaces, an integrated interactive mode of greening inside and outside warm corridors, and an interactive mode of leisure activity spaces by using such spatial layout, functional composite, and plant configuration to guide the planning of warm corridors and green spaces in cold campuses.
