摘要
在野外调查的基础上 ,对浙江北部地区保护区 (风景区、森林公园 )的青冈常绿阔叶林物种多样性进行了研究 ,并对不同地点的多样性进行比较分析。结果表明 :群落中不同层次的植物物种多样性大小不一样 ,排列顺序为 :下木层 >林木层 >草本层 ,且不同地点样地的多样性在不同层次上也是不同。样地的坡度与林木层的均匀度指数 J、坡向与林木层多样性指数 H有明显相关 ,建议对北坡及坡度较大的区域给予更大的关注。
On the basis of field investigation,the species diversity of evergreen broad-leaved forest dominated by Cyclobalanopsis glauca in protection regions are studied. The results are as follows:The order of species diversity size of the community is that:subtree layer is bigger than tree layer,the latter is bigger than herbaceous layer. The size of species diversity of different plots is various,the order of different layer differs too. There are obvious correlation between the gradient of plots and index J,the sloping direction and index H,so the northern slope and bigger gradient section must be given more attention.
