摘　　要：通过设置样方,采用Vanderloeg和Scavia选择指数对四川南充市北湖公园夜鹭生境选择行为进行了初步研究.结果表明,夜鹭喜欢选择离湖面水平距离较近,乔木郁闭度较大,保护较好而少受人为干扰的"鸟乐国"岛枸树林觅食、栖息和繁殖.By setting the sample and using the optional index of Vanderloeg and Scavia, we have had a preliminary study on the habitat selection of Nycticorax nycticorax at Beihu Park in Nanchong City. The results showed：Nyc-ticorax nycticorax at the Beihu Park preferred the island named as “Niaoleguo” with Bbroussonetia papyrifera woods to look for food, reside and reproduce, which was closer to the lake level, larger canopy density and protected better, less interfered with the human being.
