2017年春季辽河口湿地鸟类群落结构和多样性

Structure and Diversity of Bird Communities in Liaohekou Wetlands in Spring 2017

于2017年2～5月,在辽宁辽河口国家级自然保护区和盘锦辽河口省级自然保护区中,设置了15处调查小区,研究鸟类群落组成、分布和多样性。研究结果表明,在15个调查小区中,共记录鸟类72种,隶属8目13科;其中,有冬候鸟5种,夏候鸟27种,旅鸟57种;在72种鸟中,有国家一级重点保护鸟5种,二级重点保护鸟7种,列入国家重点保护野生动物名录、CITES附录I-III、中国濒危动物红皮书中的重点监测物种9种;调查区中的鸟类群落Shannon-Wiener多样性指数和Pielou均匀度指数都较大,表明该区鸟类生境质量较好。

From February to May 2017,to study the composition,distribution and diversity of bird community in Liaohekou wetlands,15 survey districts were set up in the wetlands.The results showed that a total of 72 species of birds were recorded,belonging to 8 orders and 13 families,including 5 species of winter migratory birds,27 species of summer migratory birds and 57 species of migratory birds.In the survey,a total of 5 species of national Class I protected birds and 7 species national Class II protected birds were monitored,and including 9 species listed in the National Key Protected Wild Animals List,CITES Appendix I-III,and China Red List of Endangered Animals.The Shannon-Wiener diversity and Pielou evenness indexes of bird community in Panjin Liaohekou National Nature Reserve were larger,which indicated that the habitat quality of the birds in the Liaohekou wetlands were better.
