为了解常绿阔叶林在遭受不同采伐干扰后的恢复和更新。于2003年10月至2008年10月在浙江天童地区常绿阔叶林中对5个不同采伐处理下的样地进行了5年的秋季植被跟踪调查,样地处理分别是：（Ⅰ）去除大树保留萌枝,（Ⅱ）去除地表植物保留枯枝落叶层,（Ⅲ）去除地表植物和10 cm的表土,（Ⅳ）清除下木层保留大树,以及（Ⅴ）对照.结果显示：①样地Ⅰ和Ⅱ的胸高断面积（BA）增长量最高,分别为1631.8 cm^2和1 619.4 cm^2;而样地Ⅳ的BA值增长量最少,为43.4 cm^2.②样地Ⅰ的BA值增加以常绿阔叶乔木的BA增量为主,主要通过残留植株的生长而恢复;样地Ⅱ的BA值在5年中的恢复速度最快,主要以落叶灌木或小乔木和落叶阔叶乔木的BA增量为主;样地Ⅲ的BA值恢复主要以落叶灌木或小乔木和常绿阔叶乔木的BA增量为主;样地Ⅳ中常绿树种和落叶树种都非常少,BA值都小于10cm^2.③各样地中幼苗的补充有一个波动的过程,恢复第1年最多,恢复第2年则发生锐减.样地Ⅰ中幼苗主要以常绿阔叶乔木为主.样地Ⅱ中幼苗也以常绿阔叶乔木为主,但相对样地Ⅰ有较多的落叶树种.样地Ⅲ中幼苗主要以落叶阔叶树种为主.样地Ⅳ中幼苗主要以常绿阔叶乔木为主.结果表明采伐模式对常绿阔叶林的恢复和更新有着深远的影响.择伐上木层后,常绿阔叶树种能得到较快的恢复;清除下木层,保留大树后,主要树种恢复缓慢;在皆伐下,落叶树种侵入,形成落叶树种为优势种或者常绿和落叶混交的群落.

英文摘要：

Investigations were carried out for 5 years from October,2003 to October,2008 in a logged evergreen broad-leaved forest at Tiantong,Zhejiang province.Five following treatments were used in five sites：（Ⅰ） Big trees with height8 m and DBH5 cm were removed but sprouts retained;（Ⅱ） ground surface vegetation was removed but litter retained;（Ⅲ） all vegetation and 0-10 cm topsoil were removed.（Ⅳ） undergrowth was removed but big trees retained; and（Ⅴ） a control plot without any disturbance.Our results showed that：（1） The highest BAs （basal area value） were found in plotⅠand plotⅡ,with a value of 1 631.8 cm^2 and 1 619.4 cm^2 respectively,and the lowest in plotⅣwith a value of 43.4 cm^2.（2） The increase of BA in plotⅠwas mainly from the growth of retained evergreen broad-leaved trees;plotⅡhad the highest BA increase which was mainly from deciduous broad-leaved shrubs or small trees and deciduous broad-leaved trees,and plotⅢmainly from deciduous broad-leaved shrubs or small trees and evergreen broad-leaved trees;plotⅣhad few trees with low BAs.（3） Seedling and sapling recruitment fluctuated in all plots in 5 years.In plotⅠand plotⅡ,seedlings and saplings were mainly evergreen broad-leaved trees,but plotⅡhad more deciduous trees;seedlings and saplings in plotⅢwere mainly deciduous trees while in plotⅣmainly evergreen broadleaved trees.Our results indicate that logging impact the recovery and regeneration of the evergreen broad-leaved forest trees.Under logging big trees,evergreen broad-leaved trees recover quickly;under clearing undergrowth,main trees recover slowly;under two kinds of clear-cuttings, deciduous trees invade and dominate the plots or are mixed with evergreen broad-leaved trees.
