摘要
2012年3—11月,在山西省五台县农田调查了农田害鼠的多样性及其季节变动规律。结果表明,当地农田害鼠群落为长尾仓鼠(Apodemus peninsulae)+大林姬鼠(Cricetulus longicaudatus)群落,这可为当地在灭鼠工作中确定投饵量提供理论依据;另外,当地害鼠群落的多样性指数和均匀度指数也较低,而其优势度指数偏高,主要是由当地优势鼠种之一——长尾仓鼠所占比率过高(77.12%)所致。对农田害鼠季节变动规律的研究表明,五台县农田害鼠数量一年中有1个高峰(6月),这不仅与群落自身的生态学特征有关,而且与当地气候、各物种间的相互关系和人为干扰有一定的关联。
Diversity and seasonal variation rule of farmland rodents were studied in Wutai county,Shanxi province from March to October in 2012.The result showed that dominant species of local rodent community were Cricetulus longicaudatus and Apodemus peninsulae.This provides a theoretical basis to determine feed quantity.In addition,the local rodent community diversity index and evenness index were low,and the dominance index high,due to the local dominant species of Cricetulus longicaudatus ratio is so high up to 77.12％.Study on seasonal variation rule showed that there was one peak in June about the number of farmland rodents in Wutai county in a year.This was not only related with the ecological characteristics of the community,but also related with the local climate,and all the interactions among species and human disturbance.
