The low-quality forest community stability was comprehensively evaluated by calculating subordinate function values of a model which was established based on fuzzy synthetic evaluation by a total of 30 factors of 5 indices of species diversity, soil physical properties, soil chemical properties, litter characteristics and soil carbon flux in 5 typical low-quality forest stands that mixed conifer and broadleaved forest, Populus davidiana forest, Quercus mongolica forest, Betula platyphylla forest and broadleaved mixed forest in the Greater Higgnan Mountains. The results showed that: The indices of species diversity, litter characteristics and soil carbon flux of mixed conifer and broadleaved forest are highest, the index of soil chemical properties of broadleaved mixed forest is highest, the index of soil physical properties of Quercus mongolica forest is highest, forest community stability of 5 types of forest communities in the Great Higgnan Mountains, ranked in the decreasing order of community of mixed conifer and broadleaved forest>broadleaved mixed forest>Quercus mongolica forest>Betula platyphylla forest>Populus davidiana forest. The evaluation results can provide theoretical basis for the ecosystem restoration of low-quality forest stands in the Greater Higgnan Mountains.

Key words: the Greater Higgnan Mountains, low-quality forest stands, forest community, stability
