冬候鸟草地鹨在大连机场内的越冬行为研究

Investigation on overwintering behavior for winter migrant(Anthus pratensis)in Dalian airport

为了解草地鹨的越冬行为和更好地对其进行保护,采用直接观察、定点观察等方法对大连机场内的草地鹨的越冬行为进行了观察研究.结果显示:草地鹨在每年的8月中、下旬到翌年的3月下旬在大连机场内越冬(越冬时间约210 d);草地鹨在越冬期内始终在机场内的地面上活动和栖息,且喜成群地在某一区域活动;草地鹨在雨雪天仍频繁活动,过夜时头部迎着风并处于深睡状态.针对草地鹨的行为特性,提出了建立生态保护区、招引区及改良机场草坪草种等建议.

In order to understand the overwintering behavior of Anthus pratensis and facilitate to protect it,the overwintering behavior of Anthus pratensis in Dalian airport was investigated by means of direct observation and fixed-point observation methods.The results demonstrated that the Anthus pratensis overwintered from the middle or late August of each year to the late March of the next year(the overwintering time was about 210 days),always moves and inhabits on the ground in Dalian airport,likes to move in groups in a certain area,still moves frequently in rainy and snowy days,and its head is facing the wind and in a deep sleep state during the night.According to the behavior characteristics of Anthus pratensis,some suggestions were put forward,such as,establishing ecological protection area,attracting area and improving airport lawn grass species.
