摘要:
研究森林群落主要树种的种间关系,有助于揭示植物群落的结构和功能及物种共存的维持机制. 在野外调查基础上,采用2×2联列表,通过方差比率法(VR)、χ2检验、3个关联指数(Jaccard指数、Ochiai指数、Dice指数)、联结系数(AC)以及Pearson积距相关系数和Spearman秩相关系数对南京老山国家森林公园的朴树群落中16种主要乔木的种间关系进行分析. 结果表明:群落内总体方差比率(VR)为0.95,表现为负联结,反映了该群落处于不稳定的进展演替阶段. 16个优势乔木树种组成的120个种对中,仅有1对呈显著正联结,44对呈显著或极显著负联结,而绝大多数种对联结关系未达到显著水平,这表明种对间的独立性较强.
Abstract:
Interspecific relationships among dominant species in forests are conductive to understand plant community structure and function,and to discover the mechanisms of species coexistence. According to field survey,the interspecific relationship of 16 dominant species in tree layer of Celtis sinensis community in Laoshan National Forest Park,Nanjing was studied by using variance ratio(VR), χ2-test,three association indices(including Jaccard,Ochiai,Dice)and association coefficient(AC)in the 2×2 contingency table,together with Pearson’s correlation coefficient,Spearman’s rank correlation coefficient. The result indicated that overall associations between those dominant species in the community were not significantly negative,suggesting that this community was not mature and in the phase of progressive succession.The χ2 test showed that among these 16 dominant species,only 1 species pairs exhibited significantly positive association and 44 species pairs showed that significant negative association.However,most of the total 120 species pairs did not show significant or extremely significant interconnection,reflecting that the sampled dominant species tended to distribute relatively independently and were still in the unstable succession.
