摘要
2012年10月至2013年9月,采用样带法和固定半径样点法,对内蒙古伊金霍洛旗红海子湿地公园4种生境鸟类群落结构和季节差异进行了调查,共记录到鸟类116种,隶属于16目36科,其中,夏候鸟49种,冬候鸟9种,留鸟24种,旅鸟34种.多样性指数春季最高,冬季最低.相似性指数春季和夏季最高,夏季和冬季最低.各生境鸟类群落结构季节性变化明显,鸟类群落构的变化与食物、水源、隐蔽条件、繁殖条件等因子共同作用有关.2013年4月12日在内蒙古伊金霍洛旗红海子湿地公园观察到遗鸥(Larus relictus)2340只,表明该湿地公园是我国国家一级重点保护鸟类遗鸥春季的重要取食地.本文为该湿地鸟类资源与生态环境的保护提供了基础资料.
Abstract
The community structure and seasonal dynamics of birds at four habitats in Honghaizi Wetland Park of Yijinhuoluo,Inner Mongolia were investigated from October 2012 to September 2013 utilizing line transects and the fixed-radius points method.A total of 116 bird species were recorded,which belonged to 16 orders,36 families.Among them,49 were summer visitors,9 winter visitors,24 residents and 34 passage migrants.The diversity index of birds was highest in spring and lowest in winter.The similarity index of birds was highest between spring and summer,and lowest between summer and winter.The bird community structure of each habitat changed significantly with season and interacted with food,water source,shelter conditions,breeding conditions and other relevant factors.On April 12 of 2013,a total of 2340 Relict Gulls (Larus relictus,a first class national protected bird species in China) were spotted at Honghaizi Wetland Park.This finding indicated that this area was an important feeding site for Relict Gull in spring.This study provides fundamental data for protecting wetland bird resources and ecological environment of Honghaizi Wetland Park.
