| 摘 要： | 利用样方研究了内蒙古高原东南缘森林草原过渡带植物群落多样性与环境因子的关系。在山地森林区,土壤各因子、郁闭度、坡度和坡向是控制植物物种多样性的主要因子;海拔、土壤ph值和土壤水分是限制高原森林草甸区与草甸草原区植物物种多样性的主要因子。森林草原过渡带植物物种多样性的差异是土壤、环境条件等综合因子的影响,更大程度上受海拔的影响。

| Abstract: | Applying quadrat method,the relationships betwween plant diversity and environment factors was studied in the forest-steppe ecotone in southeast edge of Innermongolia tableland.The results showed that soil factors,cannopy density,slope and aspect were the main factors influencing plant species diversity in forest zone.Altitude,soil pH and soil moisture were the main factors influencing the diversity of plant in the forest-steppe and meadow-steppe zones.The variation of plant species diversity were involved to the comprehensive influences of soil and environment factors,expecially the altitude factor. |
