摘　　要：以长白山杨桦次生林、云冷杉针阔混交林、云冷杉近原始林为研究对象,选择反映群落基本特征的种群更新潜力、土壤肥力(土壤水分和土壤养分)、林地生产力、物种多样性5项共22个因子,通过模糊数学的隶属函数值对不同演替阶段群落的稳定性进行评价.结果表明:云冷杉针阔混交林的更新潜力、土壤养分、林分生产力、物种多样性指标最高;云冷杉近原始林的土壤水分指标最高;3种森林群落的稳定性表现为云冷杉针阔混交林>云冷杉近原始林>杨桦次生林.Based on the analysis of three forest communities （ polar-birch secondary forest, spruce- fir mixed forest, spruce-fir near pristine forest） in Changbai Mountains, a total of 22 factors of 5 in- dices, including the population regeneration, soil fertility （soil moisture and soli nutrient）, wood- land productivity and species diversity that reflected community characteristics were used to evaluatethe stability of forest community succession at values of a model based on fuzzy mathematics. different stages by calculating subordinate function The results that the indices of population regenera- tion, soli nutrient, woodland productivity and species diversity were the highest in the spruce-fir mixed forest, and the indices of soil moisture were the highest in the spruce-fir near-pristine forest. The stability of three forest communities was in order of natural spruce-fir mixed forest 〉 spruce-fir near pristine forest 〉 polar-birch secondary forest.
