2010年11月1日至2011年1月2日,采用直接计数法对洱海罗时江人工湿地和沙坪湾天然湿地的水鸟多样性进行了调查,以探讨湿地管护尤其是水生植物去除对水鸟多样性的影响。结果表明：①水生植物去除后,人工湿地和天然湿地的水鸟多样性指数分别由2.08和1.86下降至1.46和1.41,这可能是由于水鸟食物量减少所致;②水生植物去除后,人工湿地的水鸟种类和密度增加,而天然湿地却降低,这可能与水草去除后单个水鸟物种数量的急剧增多有关。最后,为了给洱海水鸟提供较好的越冬环境,提出了相关的建议。

To analyze the impact of wetland management, especially removal of aquatic plants, on waterbirds diversity, a survey of waterbirds diversity was conducted by direct count method at Luoshijiang artificial wetland and Shapingwan natural wetland in Erhai lake from November 1, 2010 to January 2, 2011. The results showed that: ①after removal of aquatic plants, the waterbirds diversity indexes of the artificial wetland and the natural wetland decreased from 2.08 and 1.86 to 1.46 and 1.41, respectively, might caused by reduction of the foods and safety of waterbirds;②in contrast with to the reduction of number of species and densities of waterbirds in the natural wetland, these parameters increased in the artificial wetland after removal of aquatic plants. This might relate with the sharply increasing of one species. Finally, suggestions for effective management and conservation of waterbirds were present.
