| 摘 要： | 文章定量分析了黑龙江省胜山国家级自然保护区植物群落物种多样性与各环境因子间的关系。结果表明:保护区内各环境因子主要受土壤含水率的影响,乔木层植物多样性指数与海拔高度呈极显著正相关关系,灌木层植物多样性指数与环境因子之间的关系并不显著,草本层植物多样性指数主要受群落郁闭度、土壤有机质含量和土壤全氮含量影响较大。

| Abstract: | In this paper, the relationships between species diversity in plant community and environmental factors in Heilongjiang Provincial Shengshan Mountain National Natural Reserve were analyzed quantitatively. The results showed that： in the reserve, envi- ronmental factors were mainly affected by soil water contents, plant diversity indexes at free layers were significantly correlated posi- tivel）, with altitude, the relationships between plant diversity indexes at shrub layers and environmental factors were not significant, and plant diversity indexes at herb layers were mainly affected by canopy density, soil OM and total N contents. |
