武夷山常绿阔叶林若干优势树种的生态位分析
Analysis of niches for several dominant tree species in evergreen broadleaved forest in Wuyishan
摘要
Abstract
Wuyishan retains the primary forest ecosystem in mid-subtropical zone, which is the most perfect and typical with the largest area in the same latitude zone of world. It has great significance for conservation of Wuyishan evergreen broadleaved forest to study the competitive relationship of dominant tree species and their effects on community succession. The Shannon-Wiener and Pianka indices were collected to analyze the niche features of 11 dominant species in tree layer of subtropical evergreen broadleaved forest in Wuyishan Forest Dynamic Plot, Fujian Province, Southeastern China. The results showed as follows. The niche breadth values of dominant tree species were between 0.60 and 1.02, and most of them were large, and close to each other. There was no significant positive correlation between niche breadth values and importance values. The 55 niche overlap values were between 0.14 and 0.89 and generally high, and those higher than 0.5 accounted for 63.6%. This community was in the restoration and succession period, and the demands for resources of many species were quite similar, and their interspecific competition was fierce.关键词
