摘要: 应用基于二元数据的χ2检验、方差比率法和基于数量数据的Pearson相关系数检验及Spearman秩相关系数检验等数量方法,研究了庞泉沟国家级自然保护区(东经111°22′~111°33′,北纬37°45′~37°55′)森林群落(海拔1 600~2 430 m)21个优势种的种间关系。结果表明:研究区域内森林群落优势种群的种间关系较为松散(χ20.95N<W<

Abstract: Based upon data obtained from field investigation, the interspecific relationships among 21 dominant woody species of forest communities in Pangquangou National Nature Reserve at Mt. Guandi were analyzed by using χ2-test for 2×2 contingency table, variance ratio (VR) test, Pearson’s correlation coefficient test, and Spearman’s rank correlation coefficient test.The results clearly show that the overall association of forest communities among all species tends to no correlation (χ20.95N<W<
