镇江市环境结构对鸟类群落的影响研究

文章选取镇江市作为典型城市，就空间异质性和面积这两个环境结构因素对鸟类的影响进行了调查研究。结果表明：面积对物种数存在一定影响，这种影响在空间异质性较高时较为明显，面积对物种多样性和均匀度无显著影响；环境多样性与自然度的作用是相互独立的，而自然度的影响比环境多样性更为显著，均匀度与环境多样性存在着较显著的负相关；以鸟类为代表的野生动物与环境关系密切，城市环境的改善不仅有利于保护鸟类资源，而且更重要的是改善城市人们的生活环境。

Effects of Zhenjiang Environmental Structures on Bird Communities

Taking Zhenjiang City as the research target, this paper studied the influences of environmental structure on spatial heterogeneity and area of bird communities. It is found that the effect of area on the numbers of bird species is obvious if the spa- tial heterogeneity is high. There is no obvious influence on the diversity and the evenness of bird communities. The effects of envi- ronmental diversity and naturalness on bird species are independent, while naturalness has greater influence than environmental diversity. There is a remarkable negative correlation between the environment diversity and evenness. There is closed relationship between the wild animals, such as birds, and the environment. The improvement of environment not only benefits bird protection, but also improvement of urban living environment.
