摘要

根据出现频次选择34种优势种,利用2个×2物种存在/缺失数据列联表,采用总体关联方差比(VR)分析、χ2检验、Pearson相关系数和Spearman等级相关系数研究种间关联和相关性。34种优势种间无显著负相关关系,表明森林不稳定。经2 ×2联列表χ2检验,34种优势种561种对的种间相关性显示,正相关分别为216,149对和206对,负相关分别为345,412对和365对,正相关比分别为0.626、0.362和0.564。Spearman等级相关比Pearson相关更敏感。

Inter-Specific Correlations among Dominant Populations of Woody Syringa reticulata Communities in Wulu Mountain Nature Reserve,Shanxi Province of China
We selected 34 dominant species according to frequency and studied interspecific associations and correlations using variance ratio(VR) analysis of the overall association and χ2-test,Pearson correlation coefficient and Spearman rank correlation coefficient based on 2 ×2 contingency tables of species presence/absence data.No significant negative correlations were observed among the 34 dominant species,which suggested that the forest was not stable.Interspecific correlations among 561species-pairs of the 34 dominant species showed that 216,149 and 206 species-pairs were positively correlated,345,412 and 365 species-pairs were negatively correlated,and the positive and negative correlation ratios were 0.626,0.362 and 0.564,based on χ2-test for 2 ×2 contingency table.Spearman rank correlation was more sensitive than the Pearson correlation.
