为了探讨森林植物多样性与环境梯度的相关关系,本研究在黑龙江省帽儿山国家森林公园调查了23块不同结构的森林群落,每个群落布设的样方面积为400m2。森林植物多样性的计算采用Shannon-Wiener多样性指数,环境梯度的量化采用Whittaker的集合环境梯度计算方法,同时,采用相似性测度方法计算了Beta多样性指数。结果表明:Shannon-Wiener多样性指数随环境梯度的增大而增大,并且β多样性指数与环境梯度呈线性增加的趋势。图2表3参12。
In order to explore the relationship between forest plant diversity and environmental gradients, this study investigated 23 forest communities with different structures in Maoershan National Forest Park, Heilongjiang Province. The plot area per plot was 400 m2. The Shannon-Wiener diversity index was used for the calculation of forest plant diversity, and Whittaker’s environmental gradient calculation method was used for the quantification of environmental gradients. Meanwhile, the Beta diversity index was calculated by the similarity measure method. The results showed that the Shannon-Wiener diversity index increased with the increase of environmental gradient, and the β diversity index increased linearly with the environmental gradient.
