【摘要】 目的 :了解社区褐家鼠的洞系结构。方法 :在市区绿化带、路边、城乡结合部民居的墙边 ,用目测法发现鼠洞后逐一挖掘 ,观察其结构、洞道数量、走向、长短及功能。结果 :洞系大多为土质结构 ,一般建在离地表约 19cm处 ,占地面积约 2m2 ,容积约 15 92cm3。洞道的分布和走向视环境的不同而变化。每段洞道的长度约 3 0～ 5 0cm。其巢内一般都贮藏有废弃的食物和周围环境的垃圾。结论 :在社区用堵洞法灭鼠时 ,应注意 :一个完整的洞系 ,至少有 2～ 3个以上洞口 ,周围可能还有供逃避或伪装用的洞道更多还原

【Abstract】 Objective:To study the structure of Rattus norvgicus hole in communities of Nanning.Methods:To observe the rat hole by eyes, to dig and record amount, length and function of the rat hole. Results:Most of the holes were made of the soil built under the ground about 19 cm. An area of about 2 m 2 and capacity about 15 942 cm 3? Rat hole changes the distribution and trend with the change of environment. The each path of hole is 30-50 cm length. The rat hole stored rubbish and food which were given up for human being.
