摘要
在山西省中条山国有林管理局三交中心林场6个典型群落内设置样地,通过测算6个主要树种的生态位宽度、生态位相似比例和生态位重叠指数,分析各主要树种对资源位的利用情况以及种间关系。结果表明,三交中心林场主要树种中,油松、辽东栎为广生态位型树种,漆树、山杨、刺槐、华山松为狭生态位型树种。其中,油松为该区域的优势树种,辽东栎为其伴生树种。各树种对资源位的利用相似程度较低,且对资源位的利用程度不高。
Sample plots were set up in 6 typical communities in Sanjiao Central Forest Farm of National Forest Administration Bureau of Zhongtiao Mountain in Shanxi Province.By measuring the ecological niche width,ecological niche similarity ratio and ecological niche overlap index of the 6 main tree species,the utilization of resource niches of each main tree species and their inter species relationships were analyzed.The results showed that among the main tree species in Sanjiao Central Forest Farm,Pinus tabulaeformis and Quercus liaotungensis belonged to the broad ecological niche tree species.Toxicodendron vernicifluum,Populus davidiana,Robinia pseudoacacia and Pinus armandii belonged to the narrow ecological niche tree species.Among them,Pinus tabulaeformis was the dominant tree species in the region,while Quercus liaotungensis was a companion tree species.The similarity of resource utilization among different tree species was lower,and the degree of resource utilization was not high.
