摘要： 模拟了常绿阔叶林的4种不同受损程度(间伐大树、清理下木、清除地上植被以及植被和表土完全破坏),各设1个20 m×20 m的样地, 并与设置的1个对照样地比较, 研究其自然恢复过程中的群落动态和生境变化; 同时针对受损常绿阔叶林恢复缺乏种源的特点, 开展播种、植苗人工恢复试验. 三年来的追踪观测结果显示不同处理样地在群落物种组成、外貌及群落结构上均不相同, 呈现出不同的恢复动态.

Abstract: This paper set 4 different degradation plots(removing trees,H>8 m; removing trees, H<8 m;removing all aboveground plant;removing all aboveground plant and 0～10 cm depth surface soil) with each size being 20 m×20 m in Tiantong National Forest Park,Zhejiang province in 2003,leaving one as the comparison in the same year.Each plot was divided into two halves, one for natural restoration and the other for factitious restoration.In each plot, the habitat factors are inspected, including air temperature, humidity at the height of 0.3 m,1.5 m and 8.0 m,soil temperature and humidity in the depth of 5 cm and 20 cm, light intension in different height. In the natural restoration part of each plot, the floristic compositions and community structures were investigated in every season. In the factitious restoration part of each plot, the seeds of the dominate species were sowed and/or planted in.The germination of seeds and the growth of seedlings were studied for three years.The resnlts show that different destroyed plots have different restoration dynamics with different compositions and structures.
