摘要
笔者于1998年-2007年历时10年的时间,对喜鹊的生活习性、喜鹊巢的形态与本年降雨量进行了观察研究,其结果是喜鹊加盖巢数与6、7月份及全年总降水量呈正相关关系,加盖巢数增加,降水量就增加。
The author of this paper who spent 10 years(1998-2007) observing magpie's life habits,the formation of its nest and the amount of rainfall has arrived at a conclusion.There is a positive correlation between the building of magpie's nest and the rainfall in June and July and the whole year' rainfall.That number of building of the nest increases causes the amount of rainfall to increase.
