糙花少穗竹林主要种群生态位的研究
A Study on the Niche of the Main Tree Population in Oligostachyum scabriflorum Community
【摘要】 采用定量分析方法,对永安市安砂镇糙花少穗竹Oligostachyumscabriflorum群落中12个主要种群进行了生态位研究,以群落组成类型:①糙花少穗竹+拉氏栲(O.scabriflorum+Castanopsislamontii)群落;②糙花少穗竹+拉氏栲(O.scabriflorum+Castanopsislamontii)群落;③糙花少穗竹+细柄阿丁枫(O.scabriflorum+Altingiagracilipes)群落;④糙花少穗竹+细柄阿丁枫(O.scabriflorum+Altingiagracilipes)群落;⑤糙花少穗竹+马尾松群落(O.scabriflorum+Pinusmassoniana),及海拔梯度(170~670m)综合为一维资源位,调查5个资源位,定量测定糙花少穗竹林群落主要种群生态位宽度、生态位相似比例、生态位重叠,并分析各种群生态位的生态学意义。研究结果为进一步研究糙花少穗竹林群落稳定性、演替及糙花少穗竹天然林的经营管理、开发利用等方面提供科学的理论依据。
【Abstract】 The niche characteristics of 12 main tree populations in Oligostachyum scabriflorum forests were analysed by a quantitative method in the area of Yongan Ansha Reservoir. The niche breadth,niche proportional similarity and niche overlap of the main tree populations in O.scabriflorum forests were measured by taking community composition types :①O.scabriflorum + Castanopsis lamontii ;②O.scabriflorum + Castanopsis lamontii;③O.scabriflorum + Altingia gracilipes ;④O.scabriflorum + Altingia gracilipes ;⑤O.scabriflorum + Pinus massoniana,and the distribution types in different elevation(170~670m) as one–dimension resource states with 5 investigation plots. The ecological suggestions of the results were analyzed.The results might provide theoretical basis for studying the stability, and succession of O.scabriflorum community, and practical guidance for its management.
