辽宁长山群岛及东部沿海夏季水鸟资源调查

2003~2005年连续3年的夏季,对辽东半岛沿海滩涂以及长山群岛等40余个岛屿进行了夏季水鸟调查,旨在为辽宁省湿地的保护和管理提供基础资料。通过调查,在岛砣和沿海滩涂共记录到46种水鸟。多样性的分析表明,五四农场沿海滩涂水鸟的多样性最大,其次为南尖;而庄河湾的最小。调查发现,长山群岛的岛砣四周的海产养殖、捡卵以及旅游娱乐等人为干扰使水鸟无法安静地在岛砣上进行繁殖。沿海滩涂的庄河湾受到生活垃圾的大量排放,养虾所排放的化学药品,以及冷库的排污水,使庄河湾水域受到很大的污染;在五四农场沿海滩涂,虽然水鸟多样性较高,但其水域也受到污染,主要来自于养殖和孵卵厂的排污水。

Surveys on Waterbirds in Chanshan Archipelago and Eastern Mudflats of Liaoning in Summer

Field survey on current status of waterbirds in Chanshan archipelago and eastern mudflat of Liaoning were conducted in summer 2003-2005.Totally,we recorded 12 species in Changshan archipelago,and 43 species at eastern mudflat of Liaoning.The highest diversity index occurred at Wusinongchang and the lowest was at Zhuanghe Bay,in which lots of household garbages and shrimp ponds have been located.Although the bird diversity in mudflat of Wusinongchang is the higher,the environment there has been contaminated by chemicals from aquiculture and garbage.Many islands were faced some threats,such as egg collection,aquiculture and tourism in Changshan archipelago.Those problem produced seriously disturbs on breeding of waterbirds at the islands.Conservation suggestions have been put forward for management birds in Chanshan archipelago and mudflats of Liaoning.
