摘要
对苏州6个较大面积城市公园秋冬季鸟类物种组成、群落特征以及公园的生境特征因子进行调查和分析,并应用Pearson相关性分析方法对苏州城市鸟类与生境特征因子进行相关性分析,同时应用聚类分析方法对本次研究中的6个城市公园进行聚类分析。结果如下:观察到的鸟类38种,优势种2种,常见种14种,偶见种24种。优势种和常见种基本上反映了苏州市城市公园秋冬季鸟类群落的特征;公园绿地的自然化程度、栖息地的生境破碎化程度及灌木层盖度是影响城市鸟类丰富度和多样性的主要因素;本次研究中的6个城市公园可分为3类,分别代表了小型城市公园,半自然生境的中小型公园以及位于交通主干道区域的带状公园。
Avian species and community index in the 2^nd half-year as well as the habitat index of 6 urban parks of Suzhou are analyzed in this paper, we use Pearson correlation method to analyze the relationship between avian species＆community index and the habitat index, and then the 6 urban parks referred in this paper are classified by the method of hierarchical cluster analysis. The results are listed below： 38 species of birds are observed in the 6 urban parks, with 2 dominant species, 14 common species and 24 rare species. The index of naturalness of greenbelt, fragmentation degree of habitat and the cover degree of shrub layer are the major indexes affect the avian abundance and diversity. The 6 urban parks could be classified into 3 groups which represent the small-sized downtown, medium-sized in suburban area with natural greenbelt and strip-shaped parks beside the urban main-road.
