摘　　要：本文提出长尾黄鼠密度调查的又一方法一定点观测法,并与常规的一日弓形夹法作了对照比较。结果表明:该法调查的结果较一日弓形夹法显著地偏高1/3(P<0.05),与实际密度更为接近;两种方法的调查结果具有显著地线性相关性(r=0.9403,P<0.01),相关式为y=0.7727x-1.0909。A new method of determining the density of C. undulatus, fixed spot observation, is introduced in the present paper and compared with the routine one-day bow-clip method. Results showed that the density determined with the new method, which was more coincident with the actual density, was higher than that obtained with the routine method by 1 / 3 (P<0.05). There was an apparent linear correlation between the results obtained with the 2 methods (r = 0.9403, P < 0.01), the correlative equation being y = 0.7727-1.0909.
