摘　　要：2014—2018年共4年的冬季(11月至次年3月间),利用样线法、同步统计、定点观察等方法对昆明翠湖公园内越冬红嘴鸥的觅食生境选择开展调查研究。结果表明,红嘴鸥在翠湖公园水域的分布呈现出一定的规律,由西南向东北方向递减,且形成典型的聚集分布型。对水域面积、水面漂浮物、投食人数、植被和建筑物盖度4个觅食生境因子的方差分析结果表明,向红嘴鸥投食的人数(P<0.01)和水域开阔度主要决定了红嘴鸥觅食地的选择结果。其它生境因子影响不显著。针对研究结果提出开展文明喂鸥活动,倡导节约环保喂鸥等建议。The study on habitat selection of wintering Larus ridibundus in Cuihu Park of Kunming was carried out by line transect method,synchronous counting and point observation method in four winters(from November to March of next year)from 2014 to 2018. The results showed that the distribution of the gulls in each pools of Cuihu was regular, which decreased from the southwest to the northeast and formed a typical aggregation distribution pattern. The variance analysis for four foraging habitat factors of water area, floating objects, providing food population, vegetation and building coverage showed that the number of people who spilled food to gulls(P<0.01) and the size of water area mainly influenced the choice of feeding sites while the influence of the other factors was not significant.
