With the increasing frequency of human space activities，the quantity of space debris is growing rapidly，and the space debris issue is becoming increasingly prominent，which poses significant threats to the long-term safe and reliable operation of spacecraft，especially to the large manned spacecraft such as space stations.In this paper，the space debris threats faced by space stations and their potential hazards are systematically evaluated.In view of the design specifications and operational parameters of China Space Station （CSS） in orbit，the existing space debris handling capabilities are analyzed，and the vulnerabilities under the progressively worsening space debris environment are identified.Based on the analysis，several enhancement strategies for the space debris handling capabilities of CSS are proposed from four critical dimensions，i.e.，identification，protection，impact detection，and post-impact recovery.The feasibility and technical pathways of these strategies are thoroughly analyzed，and some strategic recommendations for the future implementation are put forward.
