摘要
以浙江省野生动物疫源疫病日常监测数据为基础,选取常见候鸟白鹭Egretta garzetta为研究对象,通过分析近5 a的监测数据,从统计学角度研究白鹭在浙江境内的分布特点和迁徙规律。结合K-means聚类分析,初步绘制了白鹭在浙江省内的2条迁徙路线,春季北上迁徙的路径:宁波鄞州—绍兴上虞—杭州余杭—湖州德清,宁波鄞州—海上,台州三门—海上;秋季南下迁徙路径:湖州德清—杭州余杭—绍兴上虞—宁波鄞州—台州三门。以德清监测站为例探索了环境因子对区域白鹭数量变化的影响,得到气温级别的回归关系方程。总结得出白鹭在浙江省的迁徙时序、数量变化活动规律。
To study distribution characteristics and migration laws of Egretta garzetta from the angle of statistics and to plot migration routes, daily monitoring data of wild animal epidemic sources and disease systems for birds of Zhejiang Province were collected. Monitoring data for the five years from 2010-2014 were analyzed by combined K-means clustering distribution to preliminarily plot two migration routes. Results indicated a northward migration path in spring of Yinzhou, Ningbo—Shangyu, Shaoxing—Yuhang, Hangzhou—Deqing, Huzhou;Yinzhou, Ningbo—over the sea; Sanmen, Taizhou—over the sea. The Southward migration path in autumn was Deqing, Huzhou—Yuhang, Hangzhou—Shangyu, Shaoxing—Yinzhou, Ningbo—Sanmen, Taizhou. Then data from Deqing Monitoring Station was selected to develop a regression equation of environmental factors that influenced changes in the number of E. garzetta. Above analysis of E. garzetta activities showed patterns of migration timing, migration paths, and quantity changes in Zhejiang Province.
