黑龙江省东部山区森林植物多样性与环境梯度的相关性研究

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。

Relationship between diversity of forest plant species and environmental gradient in eastern mountainous area of Heilongjiang Province, China

Twenty-three secondary forest communities with different structure were selected in Mao’er Mountain National Park of Heilongjiang Province, China to study the relationship between diversity of forest plant species and environmental gradient. The forest plant species diversity was analyzed by the diversity index, and the environmental factors was quantified by the method of Whittaker’s quantification of environmental gradient. Meanwhile, β-diversity indexes of communities were calculated with similar measurements. The results showed that the Shannon-wiener diversity index of forest plant species increased with the increase of the environmental gradient, and the β-diversity indexes of communities showed a liner increase along with the change of environmental gradient.
