天龙山木本群落种间关系的研究

Study on relationship between species in plant communities of Tianlong Mountain

采用χ2检验方法和相关分析等方法对山西天龙山木本植物群落进行了种间关系分析.结果表明木本植物群落的种间关系以正相关为主,但是负关联的比重也较大,而且还有一定的独立格局存在,表明物种间的关系不大稳定,群落正处于发展演替之中;同时也表明物种对环境资源的竞争并不激烈,物种资源比较丰富.

Based on the data collected from the field,the interspecific association and correlation of 58 species of the plant communities in Tianlong Mountians,Shanxi,were analyzed by using χ~2 test and Spearman's rank correlation coefficient.The result shows that interspecific relationship of the forest communities is mostly positive association,while the proportion of negative association and zero association is comparately great,which was proved that the whole community is developing and successing,and the interspecific relationship is not stabilization and rivalize for the environment rescorces is not furious.Quantity method as an important method for studying can accurately estimate the degree of the interspecific association.
