大连地区鸟类迁徙规律探讨

Migration laws of birds in Dalian areas

通过以往环志5万余只鸟类的资料统计分析,结合多年来对大连地区的生态环境及鸟类资源调查,对大连地区鸟类迁徒规律进行了研究。文章介绍了大连地区的主要鸟类停歇地有3个:蛇岛老铁山、庄河滨海湿地和四湾滨海湿地;提出了大连地区的鸟类主要迁徙路线有3条:东部沿海、西部沿海和中部丘陵山地;概述了主要的迁徙种类和部分迁徙鸟类的数量。通过对环志中常见种类的观察、比较,对大连地区的鸟类迁徙的时间顺序、迁徙的集群情况及迁徙与天气的关系等鸟类迁徙规律进行了简要的论述和初步的探讨。

By statistic analysis of data about 50,000 foot-marked birds, and combining surveys of ecological environment in Dalian areas and birds' resource, this paper concluded that in Dalian areas, major resting places for birds were Shedaolaotie Mountain, Zhuanghe seacoast marshland and Siwan seacoast marshland, major migrant routes were along eastern seashores, western seashores and central hills. Major migrant species and quantities were summarized. By observation and comparison of common birds foot-marked, this paper expounded and studied such migrant laws for birds as time, flock and relationship of migrant and weather.
