摘要
在吉林左家自然保护区对2004-2008年所悬挂的218个山雀类巢箱进行了跟踪研究,结果表明,山雀类巢箱的利用规律是:重复使用的巢箱以坡上的居多;箱口分布以北向或偏北向为主;巢箱树种的分布依次是紫椴、槐树、黑桦和槺椴.在其他变量的分析中,草本盖度、50 m内邻巢数量、箱口直径是主要影响山雀类巢箱使用频率的因子,其中草本盖度是很好的鸟类选择巢箱的指示因子.
In this paper,being hung 218 nest boxes were studied in succession from 2004 to 2008.Tits nest boxes found in the use of the law are：re-use of nest boxes on slope is in the majority.The direction distribution of nests box are mainly the right north or inclined to the north.The distribution of nest boxes tree species are Tilia amurensis,Sophora japonica,black birch,and linden Kang.In the analysis of other variables,herb cover,the number of neighbor nest boxes within 50 meters and the tree diameter of the nests box are the major influence factor of tits nest boxes using frequency.The herb cover is a good choice of bird nest boxes direct factors.
