凯里市苹果山公园鸟类多样性和季节动态

2011年6月～2012年5月对贵州省凯里市苹果山公园的鸟类进行了调查,每个季度2～3次,共9次调查。共记录到28种鸟类,隶属3目、13科。比较不同季节鸟类的α多样性指数(H')、均匀度指数(J)、优势度(C)、Jaccard相似性系数(Cj)和Bray-Curtis指数(CN)。结果表明,春季的H'和J均最高,分别为2.435和0.899;秋季的C最高,为0.158;冬季的H'、J和C指数均最低。Jaccard相似性系数最高的是春季—冬季鸟类群落,为0.375,Bray-Curtis指数最高的是夏季—冬季鸟类群落,为0.149。鸟类迁徙、食物等因素是影响苹果山公园鸟类群落结构的主要原因。

The Diversity and Seasonal Dynamics of Birds at Pingguoshan Park of Kaili

Bird surveys were carried out two to three times per season,and totally nine times,at Pingguoshan Park of Kaili City,Guizhou Province from June 2011 to May 2012.The diversity and seasonal dynamics of the bird in this park was analyzed for better understanding avian information.28 species were recorded,which belonged to 13 families and 3 orders.By comparing the biodiversity index(H′),evenness(J) and dominant index(C) among the four seasons,the results indicated that: the highest index of H′and J were 2.435 and 0.899 in spring,and the highest index of C was 0.158 in autumn,and the lowest index of H′,J and C were in winter.The similarity index of Jaccard of spring-winter avian communities was the highest(0.375),and the Bray-Curtis index of summer-winter avian communities was the highest(0.149).Migration and food are the main factors that affect the composition of avian communities at Pingguoshan Park.
