摘要
在内蒙古典型草原区测定秋季布氏田鼠的掘土危害量。结果表明 ,平均每只布氏田鼠的秋季掘土量为 10L左右 :其中挖掘仓库的抛土量为 8 0L·只 -1,占总体的 78% ,平均挖掘深度为 33 7cm ;窝巢抛土量为 0 6 8L·只 -1,占总体的 7% ,平均挖掘深度为 4 3 1cm ;洞道系统抛土量为 1 5L·只 -1,占总量的 15 %。
Dust damage caused by the digging behavior of Brandti's vole is studied in the typical steppe of Northern China in fall. Results have shown that during this period, the total dust damage is about 10 liters per vole. The cache damage is about 8 0 liters per vole, and the average carrying depth is about 33 7 cm. The nest damage is about 0 68 liter per vole, and the average carrying depth is about 43 1 cm. The damage of the burrow system is about 1 5 liters per vole during this period.
