气候背景下米埔湿地水鸟种群结构变化特征分析

The Populative Structural Change Analysis of Waterfowls under Globali-zation Background in Maipo Wetlands

选取1980年—2013年每年1月份的米埔湿地内的水鸟和7种气候要素,通过灰色关联分析的方法,探讨水鸟与气候要素的响应关系.结果表明:从整体来看,水鸟对于气候要素的关联性较强.其中,留鸟对该区气候适应能力较候鸟强;随着时间推移,水鸟对于天然气候要素的适应逐年减弱,人为因素对于水鸟数量和种类变化的影响越来越大.此外,从不同种类水鸟与气候要素的关联程度来看,不同种类水鸟对于气候的适应程度具有一定的差异性,水鸟本身的生活习性特征,决定了不同种类的水鸟对气候具有一定的适应和应对的能力.

The waterfowls in the Maipo wetland and seven climatic factors closely related to the waterfowls in January,1980—2013were selected to discuss the response relationship between the waterfowl and the climatic factor through the grey correlation analysis method.The results showed that：on the whole,the waterfowls were highly correlated with climatic factors.Among them,the resident birds had stronger adaptability to the area compared with the migratory birds.As time went on,the adaptability of the waterfowls to the natural climatic factors was weakened year by year,and the influence of human factors on the number and species of waterfowls was becoming dominant.In addition,from the degree of the correlation between different species of waterfowls and climatic factors,there was a difference between the adaptabilities of different species of waterfowls to the climate.The waterfowl’s own living habits determined that the different species of waterfowls had certain adaptability to the climate and had a certain ability to deal with the climate.
