【摘要】 四川省具有丰富的湿地资源,湿地鸟类多样性丰富。为揭示秋冬季四川湿地鸟类组成,于2016年1月、10月和11月对四川省内16个湿地(13个自然湿地,3个人工湿地)的鸟类进行了调查。共记录鸟类74种47 984只,隶属8目13科。其中,IUCN红色名录物种7种,计2 517只;国家Ⅰ、Ⅱ级重点保护鸟类6种,计116只。Shannon-Wiener指数和Pielou指数显示,三江湖、古宇湖、兴隆湖、邛海、构溪河、岷江眉山段以及长江泸州段7个湿地的多样性和均匀度较其他湿地高,面形湿地水鸟的种类和数量均大于线形湿地。10月与11月,水鸟数量与湿地面积成正的线性关系,水鸟种类与湿地面积无明显线性关系。干扰因子调查统计发现,旅游开发因子在全部调查湿地中占最高比例,在自然河段中采砂业占比高且威胁强度大。以上研究发现可为四川秋冬季湿地水鸟自然保护与生态监测提供借鉴与参考。更多还原

【Abstract】 Sichuan Province is abundant in wetland resources and diversity of wetland birds.To reveal the composition of winter wetland birds in Sichuan Province,the birds of 16 wetlands(13 natural wetlands,and 3 artificial wetlands) in Sichuan province were investigated in January,October and November of 2016.A total of 74 species are recorded with a total number of 47 984,belonging to 8 orders and 13 families.Among them,there are 7 species of IUCN red list with the number of 2 517,and 6 species with the number of 116 classified intoⅠ and Ⅱ level nationally protected birds.The shannon-wiener index and Pielou index show that the seven wetlands of Sanjiang Lake,Guyu Lake,Xinglong Lake,Qionghai Lake,Gouxi River,Meishan section of Minjiang River and Luzhou section of Yangtze River are higher in diversity and evenness than other wetlands,and its waterfowl species and quantity of regular wetland are larger than that of linear wetlands.In October or November,a positive linear relationship between waterfowl quantity and wetland area is detected while no obvious linear relationship between the waterfowl species and the wetland area is found.According to the statistics of disturbance factors,tourism development factors account for the highest proportion in all surveyed wetlands,and sand mining industry with a high threat intensity account for a high proportion in the natural river reach.The above findings can provide some guidelines for the natural protection and ecological monitoring of waterfowls in autumn and winter at the wetlands of Sichuan Province.更多还原
