| 摘 要： | 对万木林中亚热带常绿阔叶林林隙的两个边缘区,运用Shannon-W iener物种多样性指数、生态优势度指标以及边缘效应强度指数,对其边缘效应现象进行了研究。结果表明:用物种多样性指数测定的林隙边缘区的边缘效应强度值为0.843 3~1.191 3;而用生态优势度值测定的林隙边缘区的边缘效应强度值为0.653 1~2.740 3。

| Abstract: | This paper explores the characters of the gap edge effect of central subtropical evergreen broad-leaved forest in Wanmulin.The species diversity and ecological dominance as well as the index of the edge effect were measured,on the basis of Shannon-Wiener index and Simpson index as well as the index of the edge effect.The results showed that the index of the gap edge effect in the gap border area was about 0.843 3~1.191 3 on the basis of the species diversity;based on the measurement of the ecological dominance index,the index of the gap edge effect in the gap border area was about 0.653 1~2.740 3. |
