摘要
园林鸟类是城市环境质量的重要指标,也是城市自然保护和生态建设的重要组成部分. 1997年10月至1998年12月,通过选取杭州市区2 0个主要园林,根据季节每月一至两次调查园林鸟类的物种和数量,对杭州市园林鸟类的群落结构及其季节变化进行了分析探讨,结果显示:全部园林中共记录到鸟类82种,其中迁徙鸟类5 0种,占6 1% ,留鸟32种,占39% ;园林鸟类群落呈现出较强的季节性,从全部园林总体上看,物种数和总数量呈现春秋两个高峰,夏季最低;从单个园林来看,多数园林鸟类群落物种数的最高峰集中在冬季,而各园林鸟类总数量的季节变化呈现不同程度的波动性.
Bird community is an important environmental index, and the conservation of urban birds is also an important component of natural conservation and ecological construction of a city. During Oct,1997 to Dec,1998, the species number and abundance of the bird communities among 20 woodlots in Hangzhou city area were surveyed one or two times every month according to different seasons. 82 species were record. Among them, 50 were migrant, accounting for 61% of total avifauna and 32 permanent residents, accounting for 39%. The bird community structure and seasonal variation were analyzed. The results showed that the bird community structures changed greatly between seasons. The species number and abundance in all woodlots appeared two peaks in spring and autumn, the lowest in summer. According to individual woodlot, the species number of bird community in most of woodlots got the peak in winter. The abundance of bird in each woodlot fluctuated between seasons.
