摘要

以大兴安岭1987年"5.6"大火后火烧迹地经过植被恢复后的4种林分类型为对象

利用灰色关联分析法分析了植物多样性与土壤环境因子的关系。研究结果表明

群落物种多样性指数由大到小依次为:樟子松林>兴安落叶松林>山杨林>白桦林。物种多样性在垂直层次上的变化差异较大。土壤理化性质存在一定差异

其中樟子松的土壤理化性质较其他3种林分类型差。4林分类型群落物种多样性与土壤环境因子之间的关联度均大于0.5

但关联程度不同。樟子松林和山杨林的Shannon-Wiener多样性指数、物种均匀度指数、物种丰富度指数与土壤容重的关联程度最大

兴安落叶松林和白桦林的3个多样性指数与非毛管孔隙度的关联程度最大。樟子松林、兴安落叶松林和白桦林的Shannon-Wiener多样性指数、物种均匀度指数、物种丰富度指数与有效磷的关联程度最大

而山杨林的3个多样性指数与有效磷的关联程度最小。

Abstract

The correlation between biodiversity and soil physiochemical properties were analyzed under four stand types in Great Xing′an Mountains

which were restored since burned in 1987

using the gray relational analysis.The results showed that the biodiversity varied substantially among four different stands

demonstrating a descending order of biodiversity as Pinus sylvestris var.mongolica plantationLarix gmelini plantationPobulus davidiana natural forestBetula platyphlla natural forest.The soil physical and chemical properties also varied;Pinus sylvestris var.mongolica plantation was found under the poorest condition.The grey relational coefficient between biodiversity and soil environment exceeded 0.5 for all the four stands

showing different correlations.Shannorr-Wiener index

evenness index and species richness index correlated closely with soil bulk density under Pinus sylvestris var.mongolica plantation and Pobulus davidiana natural forest

whilewith non-capillary porosity under Larix gmelini plantation and Betula platyphlla natural forest.The three indices were also found correlated closed with available phosphorus under the Pinus sylvestris var.mongolica plantation

Larix gmelini plantation and Betula platyphlla natural forest

except for Pobulus davidiana natural forest.
