摘要
2006年8月至2007年7月,采用系统抽样技术和样带法,对广东省江门市新会区银湖湾湿地鸟类群落进行研究,共记录70种,隶属13目28科48属。新会银湖湾湿地带鸟类平均密度356只/hm2,鸟类物种多样性指数3.690 2、均匀度指数0.875 6、优势度指数0.25。芦苇红树林潮间湿地、鱼塘莲藕湿地和农田果园是新会银湖湾湿地典型的生境,各生境的鸟类种类、密度和多样性差异较大。其中芦苇红树林潮间湿地55种,平均密度338只/hm2;鱼塘莲藕湿地有40种,平均密度279只/hm2;农田果园有38种,平均密度247只/hm2。3种生境中芦苇红树林潮间湿地鸟类的生物多样性最高,农田果园最低。
The bird community in Xinhui Yinhuwan wetland,Jiangmen City,Guangdong Province was studied from August 2006 to July 2007 with the systematic sampling and line transects.The results showed that there were 70 species,belonging to 13 orders,28 families and 48 genus.The average density of birds in Xinhui Yinhuwan wetland was 356 ind./hm2.The Shannon-wiener index(H′) was 3.6902,species evenness(J) was 0.8756,and superiority index was 0.25.The species richness,density and diversity index were significantly different among habitats.55,40 and 38 species were recorded in reed mangrove inter-tidal wetland,fishpond lotus root wetland and farmland orchard habitats;and the average density of birds was 338 ind./hm2,279 ind./hm2 and 247 ind./hm2,respectively.The diversity index of the avian community in reed mangrove inter-tidal wetland was the highest while that in farmland orchard habitats was the lowest.
