群居性啮齿动物重捕取样布笼方式的比较

采用两种布笼方法即传统的方格布笼法和同心圆布笼法对典型草原区布氏田鼠野外种群进行了重捕效果的比较。结果表明，方格布笼法的重捕效果要大大低于同心，圆布笼法。对此类群居性啮齿动物进行重捕取样的实验设计时，建议采用同心圆布笼法取代传统的方格布笼法。

Comparing the Trap Patterns for Marking-Recapture Sampling Social Rodent

Two trap patterns, namely the Circle grid and the Square grid, were compared by live trapping the field population of Brandt's vole in typical steppe in Inner Mongolian grassland. Results revealed that the traditional Square gird pattern possessed much lower trappability than the Circle grid one. It might be considered to apply Circle grid instead of Square grid in the marking recapture census for social rodent.
