摘要
对 1996~ 1998年大方县高山姬鼠种群数量季节变化规律的研究表明 ,高山姬鼠主要分布于稻田、旱地耕作区 ,是大方县农田害鼠优势种 ,占农田害鼠总鼠数的 56 .75%。 3年平均捕获率为 (3.4 4± 2 .12 ) % ,一年中种群数量在 6月出现一个高峰 ,平均捕获率达 8.2 5%。全年种群数量消长季节曲线呈单峰型。数量峰 6月种群数量与早春 2月发生基数密切相关。
Seasonal population dynamics of Apodemus chevieri was studied from 1996 to 1998 in Dafang county.The results showcd that Apodemus chevieri is a dominant mouse species,which takes up 56.75% of total number of all mouse species in field.Annual capture rate of the mouse is 3.44±2.12% in average for ten year. There are two peaks in population development. First peak appears in March each year.The capture rates at first peak is 8.25%.
