内蒙古民航机场鸟类区系组成的差异及分析

Differences and Analysis of Avifauna Composition at Civil Airports in Inner Mongolia

从2007年9月至2009年5月,利用样带法和固定半径样点法对内蒙古自治区海拉尔、乌兰浩特、通辽、赤峰、锡林浩特、包头、鄂尔多斯等7个民航机场及其周边7km范围内的鸟类区系进行了调查.共记录到鸟类234种,隶属于18目52科.通过对鸟类区系组成比较,分析了各机场鸟类区系组成差异.结果表明,赤峰机场与通辽机场的鸟类区系组成差异最小,锡林浩特机场和乌兰浩特机场的鸟类区系组成差异最大.包头机场与其他各机场相比,鸟类区系组成差异均较大,通辽机场与其他各机场的鸟类区系组成差异均较小.同时探讨了鸟类区系差异形成的原因.

From September 2007 to May 2009,the avifauna distributed in the 7 civil airports in Inner Mongolia were investigated, including Hailer, Ulanhot, Tongliao, Chifeng, Xilinhot, Baotou and Ordos. A total of 234 bird species belonging to 52 families and 18 orders were recorded. Based on the comparison of the avifauna composition, the differences of the avifauna composition in the civil airports were discussed. The results showed that the avifauna difference between Chifeng and Tongliao civil airport was the smallest, and the avifauna difference between Xilinhot and Ulanhot civil airport was the biggest. Baotou civil airport had the biggest avifauna differences among the seven airports on average and Tongliao civil airport had the smallest one. The reasons for the difference of avifauna composition were discussed.
