摘　　要：【目的】研究辽宁仙人洞国家级自然保护区9个典型森林群落稳定性,探讨其主要影响因素。【方法】以保护区9个典型森林群落的样地调查数据为数据源,比较各森林群落种群更新潜力、群落基本特征、物种多样性、种群生态位重叠、凋落物特性和土壤肥力差异,以此6项指标共44个因子构建群落稳定性评价体系,应用模糊数学中隶属函数值法对各森林群落稳定性状况作出评价。【结果】①赤松Pinus densiflora+麻栎Quercus acutissima-地锦Parthenocissus tricuspidata+青花椒Zanthoxylum schinifolium-两型豆Amphicarpaea edgeworthii+白花碎米荠Cardamine leucantha群落种群更新潜力、物种多样性和土壤肥力最好,赤松-牛叠肚Rubus crataegifolius+青花椒-矮丛薹草Carex callitrichos var.nana群落生长发育基本特征平均值最高。9个群落种群生态位重叠情况相似,槲树Q.dentata+麻栎-花木蓝Indigofera kirilowii+榛Corylus heterophylla-菴闾Artemisia keiskeana+矮丛薹草群落凋落物层蓄积量和持水性最高。②9个森林群落的稳定性排名由高到低依次为赤松+麻栎-地锦+青花椒-两型豆+白花碎米荠群落、槲树+麻栎-花木蓝+榛-菴闾+矮丛薹草群落、麻栎+栓皮栎Q.variabilis-青花椒+榛-矮丛薹草群落、赤松-三桠乌药Lindera obtusiloba+照山白Rhododendron micranthum-矮丛薹草群落、赤松-青花椒-矮丛薹草群落、蒙古栎Q.mongolica+赤松-牛叠肚+照山白-矮丛薹草群落、蒙古栎-牛叠肚-矮丛薹草群落、赤松-牛叠肚+青花椒-矮丛薹草群落、槲树+赤松-榛-矮丛薹草群落。③6项森林群落稳定性评价指标中,第1主成分中种群更新潜力、物种多样性和土壤肥力的荷载系数最大。【结论】辽宁仙人洞国家级自然保护区9个典型森林群落稳定性存在显著差异,其主要影响因素为森林群落种群更新潜力、物种多样性以及土壤肥力。[Objective]The objective of this study is to evaluate the stability of 9 typical forest communities in Xianrendong National Nature Reserve,Liaoning Province,and to analyze the main influencing factors.[Method]Taking the survey data of 9 typical forest communities in the reserve as the data source,the population regenerative potential,basic community characteristics,species diversity,population niche overlap,litter characteristics and soil fertility of 9 forest communities were compared,and a stability evaluation system was constructed based on the above 6 indicators and 44 factors.The subordinate function value method in fuzzy mathematic was used to evaluate the stability of each forest community.[Result](1)Pinus densiflora+Quercus acutissima-Parthenocissus tricuspidata+Zanthoxylum schinifolium-Amphicarpaea edgeworthii+Cardamine leucantha had the best regeneration potential,species diversity and soil fertility.The average value of basic characteristics of growth and development of P.densiflora-Rubus crataegifolius+Z.schinifolium-Carex callitrichos var.nana community was the highest.The niche overlap of the 9 communities was similar,and the litter accumulation and water holding capacity of Q.dentata+Q.acutissima-Indigofera kirilowii+Corylus heterophylla-Artemisia keiskeana+C.callitrichos var.nana community were the best.(2)The stability ranking of the 9 forest communities from high to low was P.densiflora+Q.acutissima-P.tricuspidata+Z.schinifolium-A.edgeworthii+C.leucantha,Q.dentata+Q.acutissima-I.kirilowii+C.heterophylla-A.keiskeana+C.callitrichos var.nana,Q.acutissima+Q.variabilis-Z.schinifolium+C.heterophylla-C.callitrichos var.nana,P.densiflora-Lindera obtusiloba+Rhododendron micranthum-C.callitrichos var.nana,P.densiflora-Z.schinifolium-C.callitrichos var.nana,Q.mongolica+P.densiflora-R.crataegifolius+R.micranthum-C.callitrichos var.nana,Q.mongolica-R.crataegifolius-C.callitrichos var.nana,P.densiflora-R.crataegifolius+Z.schinifolium-C.callitrichos var.nana and Q.dentata+P.densiflora-C.heterophylla-C.callitri
