摘要
采用时间序列分析方法,研究了长白山红松阔叶林鸟类多样性的季节格局。结果表明Shan non多样性指数季节格局表现为春秋高、冬夏低的双峰型特点,并与物种、数量和优势度之间有极显著的相关关系;群落各指数季节间的显著差异主要表现在冬季与其他各季之间;各月前两个优势种的比例在多样性格局构成中具有非常重要的作用;5月前和9月后,气温对Shannon指数格局的影响极为显著(r=0 9209,P<0 01)。
The seasonal patterns of avian species diversity in korean pine /broadleaf forest in Changbai Mountain were studied by time series analysis. The results showed that the seasonl pattern of Shannon diversity index appeared to be bimodal, namely it was higer in Spring and Autumn, and was lower in Winter and Summer for Shannon index,which had a very significant correlation to the numbers of species and individuals and the dominance.The significant difference of community indices between seasons was mainly occurred in Winter from other seasons.The two most dominant species in every month was very important in the structure of diversity patterns.The effect of air temperature on Shannon index pattern was very significant(r=0.9209, p<0.01) from September to May.
