The construction of shelterbelt system is an important part of ecological construction. In recent years, some of the Shelterbelts have been degraded, which directly leads to the decline in the function of the shelterbelts, which poses a threat to the ecological security of the land, and affects the improvement of the achievements of the forestry ecological construction. Taking the construction of protective forest in Luxi County as an example, this paper, starting with the construction role and management status of protective forest, deeply analyzes the reasons for the degradation of shelterbelts, deeply expounds the necessity and feasibility of the restoration of the degraded shelterbelts, rationally puts forward the restoration ways of the degraded shelterbelts, and points out that the restoration of degraded forest protection is a scientific way to improve the protective effect of the protective forest. It is very important for improving the structure of shelterbelt, promoting the development of forestry, promoting the construction of ecosystem and maintaining the balance of ecosystem.
