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.
 

Abstract: 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 indices, including the population regeneration, soil fertility (soil moisture and soli nutrient), woodland productivity and species diversity that reflected community characteristics were used to evaluate the stability of forest community succession at different stages by calculating subordinate function values of a model based on fuzzy mathematics. The results that the indices of population regeneration, 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.
