典型水土流失区地面鼠类的数量配置及季节变动规律

The Dispose of Species and Quantity of Rodent on Typical Water and Soil Loss Region

调查明确了黄土残塬沟壑区地面鼠类在不同地貌类型中的种类和数量组成 ,并分析了不同季节的数量分布特点 :长尾仓鼠、子午沙鼠和大仓鼠 3种害鼠分别为塬、沟、坡这三种地貌类型中的优势种 ;害鼠种类和数量在不同的植被和地貌类型中存在明显的差异 ,其密度季节性波动较大。本项研究为典型水土流失区害鼠综合治理对策的制定提供了科学依据。

The authors have investigated and definituded the composition of species and quantity of ground rodents in different physiognomy type in broken loess plateau gully region,analyzed the distributing characteristic of rodent on different season, Lesser long tailed hamster, Little Chinese jird and Greater long tailed hamster were superority species in 3 physiognomy type,plateau form, gully form and slope plot. The result indicated that species and quantity are different by vegetation and physiognomy, and change of density is more distinct along with changing season. It has offered scientific basis for integration control.
