晋中盆地植物多样性的梯度分布规律研究

Study on Gradient Distribution of Plant Diversity in Jinzhong Basin

研究区域植物多样性分布规律对于植物生态环境的保护有重要的意义。以晋中盆地为研究对象,通过设置样方,得出了植物多样性沿城区-郊区-农区的分布规律,在晋中盆地内的县(区、市)的任何一个方向上,随着距离县(区、市)驻地的距离增加,植物多样性也相应增高。用一元回归方法为县(区、市)周围多方向建立了一个植物多样性梯度分布数学模型,模型表明随着距离县(区、市)驻地的距离增加,植物多样性也相应地呈现出线性增加。

The study of regional plant diversity distribution has great significance for the protection of ecological environment. This study selects Jinzhong basin as the research object. By setting the plot,this paper generates the distribution regularity of plant diversity along the urban-suburban-rural areas. The research finds that in any outward direction of counties（ district or city） in the Jinzhong basin,as the distance from the county（ district or city） center increases,the plant diversity also increases. The paper also establishes a model of plant diversity gradient distribution with regression which shows that as the distance from the county（ district or city） center increases,the plant diversity also shows a linear increase.
