云南泸沽湖省级自然保护区鸟类多样性

Bird Diversity of the Provincial Nature Reserve of Lugu Lake in Yunnan

2016年6月至2017年3月,于旱季与雨季分别开展泸沽湖省级自然保护区鸟类多样性调查,对比不同生境鸟类多样性组成,以期反应泸沽湖退耕还湿的成效。结果表明:泸沽湖现有鸟类120种,隶属15目44科。其中留鸟63种,候鸟46种。基于不同生境鸟类相似性指数,无论是旱季还是雨季,退耕还湿区和林地相似性最高;退耕还湿区在雨季形成了季节性沼泽,但水鸟却仅6种,远低于林鸟;旱季退耕还湿区因水位下降归于旱地,不利于水鸟栖息。泸沽湖实施退耕还湿工程后,目前退耕还湿区对鸟类栖息的服务功能与陆地更为相似,作为湿地的服务功能相对较弱。

We investigated the bird diversity of Lugu Lake Provincial Nature Reserve in dry and rainy seasons from June 2016 to March 2017. The diversity of birds in different habitats was compared in order to assess the effect of wetland restoration project. The results showed that a total of 120 bird species(resident birds=63;migrant birds=46) belonging to 44 families and 15 orders were recorded. No matter in dry season or rainy season, the similarity coefficient of bird communities was the highest between wetland restoration area and woodland. The wetland restoration area has became seasonal swamps in the rainy season and there are only 6 water birds, which is much less than that of forest birds. The seasonal swamps became dry land in the dry season and water birds have declined. The ecological function of wetland restoration area is more similar to terrestrial ecosystem, and regard as the wetland, the function of ecosystem is weak.
