| 摘 要： | 在封闭种群中,通过标记重捕和标记夹捕法对农田害鼠的种群数量N,捕获率P和密度D进行了估计.分别为72,0.1528,42只/公顷和85,0.1882,55只/公顷.两种方法间结果差异不大.使夹捕法可用以估计害鼠种群数量,扩大其应用前景.

| Abstract: | In a closed farmland rodent population,Sizing is carried out by both capture-marcking-recapture and marckingdead trapping methods.(?)and (?) are found to be 72,0.1528,42/hec,and 85,0.1882,55/hec.respectively.There is no distinct difference between this two methods.This makes it possibile to size rodent population by deadtrapping. |
