摘要: 根据对重庆缙云山风灾迹地人工混交林生态恢复的连续调查资料,采用Simpson指数(D),Shannon-Wiener指数(H′)和Pielou 均匀度指数(J)进行α多样性测度,采用Sorenson指数,Bray-Curtis指数和Morisita-Horn指数进行β多样性测度。结果表明: 木本植物α多样性在时间尺度上的变化随人工混交林演替的进行而增大,草本植物的α多样性则减少;β多样性指数在不同的时间尺度上差异明显,说明风灾迹地人工混交林生态恢复过程中物种的周转速率相对较快,一些人工种植的针叶树种被常绿阔叶树种代替,这一特点反映了风灾迹地人工混交林向地带性植被常绿阔叶林的方向发展的趋势。

AbstractIn June 1989, a catastrophic storm hit Jinyun Mountain, and destroyed much of forest. After this storm, the Jinyun Mountain Natural Protection Bureau planted Pinus massoniana, Gordonia acuminata, Castanopsis carlessii var. spinulosia, and Symplocos setchuanenesis,etc. on the wind-damaged slash. At the same time we established fixed sample plots at the site of wind-damaged slash and investigated the species, quantity and growth state of the plants at the wind damaged slash in 1990, 1992, 1994, 1996, 1999 and 2001. On the basis of the investigation into ecological restoration of artificial mixed forest of wind damaged slash in Jinyun Mountain, we computed the Simpson index, Shannon-Wiener index, Pielou index, Sorenson index, Morisita Horn index, and Bray-Curtis index. The result indicates that a diversity of woody-plants increases with artificial mixed forest succession while that of grassy-plants decreases. On different time-scales, b diversity is obviously different. This indicates that artificial mixed forest of wind-damaged slash has high species turnover rates, and evergreen broad-leaved species have replaced some coniferous species. It is concluded that artificial mixed forest of wind-damaged slash tends to become evergreen broad-leaved forest.
