摘要
本文在样方调查的基础上,对江苏徐州泉山、吴县光福、宜兴龙池和句容宝华山四个森林生态系统保护区内的典型植被类型的材积量增长和群落结构的变化进行了估算和统计,并对比保护区建立前后的有关样方资料,证明各保护区在建立8～10年后均发生了明显的变化,地带性物种种群和群落的恢复均比较迅速。
According to the data from the quadrat sampling method, the increase of timber volume and the change of community structure of the typical vegetational forms in four forest reserves (Quanshan reserve, Xuzhou city; Guangfu reserve, Wuxian county; Longchi reserve, Yixing county and Baohuashan reserve, Jurong county) of Jiangsu Province were estimated and analyzed statistically. Compared with the data collected before the establishment of the reserves, it showed that after the reserves have been established for 8 ~ 10 years, every reserve has significantly improved. The recovery of the zonal plant populations and communities was relatively rapid in the reserves.
