祁连山自然保护区啮齿动物取食活动初步研究

Preliminary Study on Feeding Behaviour of Rodent in Qilian Mountain for Nature Reserve

研究了祁连山自然保护区内分布的36种啮齿类动物的取食活动情况.结果表明,当前对林业生产造成危害的主要为中华鼢鼠、达乌尔鼠兔、子午沙鼠和长爪沙鼠4种,灾害种为中华鼢鼠.大部分啮齿动物处在生态系统中食物链的中间环节,是许多食肉动物的食料.因此,应遵循生态学原理,充分保护利用自然界天敌动物调节鼠兔的种群数量,达到长期控制鼠兔害的目的.

The feeding behaviour of 36 species of rodents in Qilian Mountain for Nature Reserve was studied.The results showed that Myospalax fontanieri,Ochotona daurica,Meriones meridianus,M.unguiculatus cause damage for forest production.Most of rodents in the middle of food chain in ecosystem are foodstuff for many animals.According to the principle of ecology,the amount of mice and hares was controlled by protecting natural animals in nature in order to control the damage of mice and hares in the long term.
