呼和浩特市市区春季鸟类群落结构及多样性研究

The Study on the Structure of Avian Community and Species Diversity in Hohhot City in Spring

2004年4月对呼和浩特市市区不同类型城市化栖息地的鸟类分别进行了调查.共记录到鸟类32种,隶属于19科,9目.研究了不同类型栖息地中鸟类群落的多样性、均匀度、丰度、种间相遇机率等群落特征.调查结果显示:不同类型栖息地中,公园、苗圃的鸟类多样性和均匀度最高;商业区、交通占地的鸟类多样性和均匀度最低.

During the spring of 2004,studies were conducted to investigate the community and species diversity of spring birds community in Hohhot which includes seven different urbanization level habitats. In total,32 species,which belong to 19 orders,9 families,were recorded. Based on the principles of community ecology,we evaluate and discuss structural characteristics by means of the Shannon-wiener index(H′),species evenness(J),richness index in spring bird community . The results indicated that: the diversity index and species evenness in park and nursery are the highest in seven typical habitats,on the contrary,the diversity index and species evenness in shopping center and traffic occupancy are lower than others.
