环境因子对植物物种多样性的影响研究进展

Effects of Environmental Factors on Plant Species Diversity:Research Progress

植物物种多样性动态规律是现代生态学研究的热点之一,其空间分布格局受诸多环境因子的影响。由于不同环境因子之间的复杂关系及其与植物群落间的耦合作用,使其对环境因子改变的响应已成为全球变化科学领域的热点问题。为深入了解环境因子对植物物种多样性的影响,笔者综述了国内外近年来的相关研究成果,从地形因子(海拔、坡度、坡向、坡位)、土壤因子(土层厚度、氮含量、磷含量、p H值)、气象因子(光照、温度、水分)等方面分析了环境因子对物种多样性的影响,可为科学评估物种多样性对环境因子的响应机制提供相应参考数据。

Plant species diversity dynamic regulation is one of the hotspots of modern ecology research, and the spatial distribution pattern of plant species diversity is affected by many environmental factors. Due to the complex relationship of different environmental factors and the interaction between these factors and plant communities, the response of plant species diversity to environmental factors has been a hot topic in the field of global change science. To further understand the influence of environmental factors on plant species diversity,the authors reviewed related research results, analyzed the effects of environmental factors on species diversity from topographic factors（altitude, slope grade, slope aspect, slope position）, soil factors（soil thickness,nitrogen content, phosphorus content, pH value） and meteorological factors（light, temperature, moisture）. The study could provide corresponding reference data for scientific assessment of the response of species diversity to environmental factors.
