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.
