摘要
采用样方、样线调查法,对保护区与边缘地区同等条件的火烧迹地分别与其未过火林地进行对比,分析了不同火烧迹地天然更新情况。结果认为,在火后恢复初期,乔木层平均高和平均胸径比火烧前增加;灌木层灾后重新郁闭的片层,盖度、平均高低于未烧林地,生活力较强;野生动物物种丰富度降低。
By taking methods of sample plots and line transect survey, nature restoration status at burned area and unburned area under same conditions in the nature reserve and a rounding area have been ana- lyzed in this paper. Results showed that in the initial rrestoration stage after fire, the average height and average DBH of trees were higher than control; the crown closure, coverage, average height of shrub layer were lower than control, with strong vitality; species richness of wildlife was reducein.
