凤阳山自然保护区鸟类调查

A Survey on Birds of Feng Yang Mountain Natural Reserve, Zhjiang Province

本文记录了1980年春夏季和冬季对凤阳山自然保护区鸟调查的74种鸟,隶属于10目24科,其中14种为本省当时的新记录,留鸟占总数的70％;东洋界种类占63.5％。区系组成上具有华南区的特色。 以大田坪(1220米)和夏边(650米)两地为调查点。两地春夏季鸟类的群体密度无显著性差异,大田坪的多样性指数(H′)高而群落的优势度指数(C)小;冬季两地的群体密度具极显著差异,夏边的H′值高而C值小。 此外,在春夏季观察了鸟类的繁殖活动并记述了采到的五种鸟巢及内容。

An avifauna survey was conducted in Feng Yang Mountain Natural Reserve of Zhejiang Province in the spring, summer and winter of 1980. 74 species of birds were found, belonging to 10 orders and 24 families, of which 14 species were new records in Zhejiang Province at that time. Among them, the resident birds accounted for 70% of the total avifauna and the birds of the Oriental realm amounted to 63.5% in this area. According to zoogeographical regions of China, the fauna were possessed of the avifaunal characteristics of South China region in this natural reserve.In this paper, the density, diversity and vertical distribution of avian community were discussed. The present investigation was carried out at Da Tian Ping (1220 metres above sea level) and Xia Bian (650 metres). In spring and summer, there was no marked difference between Da-tiang Ping and Xia-Bian in the colonical densities of the birds. But the value of the bird community diversities was larger for Shannon-Wiener index (H') and smaller for Simpson index (C) at Ta Tian Ping.However, there was marked difference in winter. The value of H was larger and C was smaller at Xia-Bian, and the value of C was related with the density of the dominant avian population. Owing to the different altitude above the sea level, the avian community component was different between Da Tian Ping and Xia Bian. It was obvious that the avian community component was related with the avian vertical distribution.In addition, 5 species of birds were observed about their breeding and nesting behavior in spring and summer.
