缙云山风灾迹地恢复群落植物物种多样性

Study on Species Diversity of the Restorable Community of the Wind-damaged Slash in Jinyun Mountain Nature Reserve

以缙云山自然保护区风灾迹地恢复群落5个样地调查资料为基础,研究了缙云山自然保护区风灾迹地恢复群落物种多样性的特征.结果表明:各样地间多样性指数测值变幅不大,物种多样性在群落不同层次的变化规律为:灌木层>乔木层>草本层.

The restorable community characteristics of the wind-damaged slash in Jinyun Mountain Nature Reserve are studied by field investigation.The results show that the twenty-year wind-damaged community in Jinyun Mountain Nature Reserve had high species diversity index,which did not alter too much with investigated plots,the orderof the magnitude of species diversity was ： shrub layertree layerherb layer.
