乌梁素海鹳形目鸟类生态分布和动态变化研究

Study on the Ecological Distribution and Dynamics of Ciconiiformes in Wuliangsuhai

2014-2016年对内蒙古乌梁素海鹳形目鸟类种类组成、生态分布、季节动态进行了调查研究.结果:共观察记录到2科8属10种,均属于夏候鸟;有国家Ⅱ级重点保护鸟类白琵鹭(Platalea leucorodia)1种.分布生境分为湖岸浅滩地及草地、鱼池及岸边、蒲苇丛和湖中捕鱼网具,其中蒲苇丛是该10种鸟的繁殖生境.春季迁徙期为3月上旬至5月上旬,秋季迁徙期为9月中旬至11月上旬,迁徙时间和居留期因种类而不同.另外,分析了30年乌梁素海鹳形目鸟类年际动态特征.

A study on the species composition,ecological distribution and seasonal dynamics of Ciconiiformes was investigated in Inner Mongolia Wuliangsuhai from 2014 to 2016.The results showed：a total of10 species of Ciconiiformes belonging to 2 family 8 genera were recorded.All species are summer visitors.White Spoonbill is listed as grade Ⅱ national protected species.Shallow lakeshore beach,grassland,fish pond and shore,reeds and fishing nets are their mainly distributed habitats.The reeds are the nesting and breeding habitats of all species.In spring,the migration period is early March to early May,in autumn,it is mid-September to early November.The migratory time and residence period are different among species.The features of species composition and interannual dynamics of Ciconiiformes in Wuliangsuhai in the last30 years were analysed.
