摘　　要：目的对原有食饵法进行改进,创建新的鼠饵盒法对鼠密度进行监测,并对该方法的可行性进行初步探讨。方法在鼠密度较高的试验场所内,长期观察鼠类对饵料的取食情况,测定鼠饵盒阳性数及鼠饵失重量。结果在鼠密度相对稳定的状况下,鼠饵盒阳性率及日均失重量线性相关,符合逻辑斯蒂曲线,60d左右达到最高且趋于稳定。结论该方法适用于长期连续对某一地区的鼠密度进行监测。Objective To improve original bait method, establish new bait-box method for monitoring rodent density, and primarily discuss the feasibility of the methods. Methods The quantity of bait eaten by rodents was observed. The masculine rate of bait-box and the bait＇s daily-losing-weight were tested in the area where the rodent density being in a high level. Results The masculine rate of bait-box and the bait＇s daily-losing-weight were linear interrelated. Two curves were fit logistic curve in density of rodent while the real density of rodent was relatively stable. They reach maximum and tend to be stable in 60th day. Conclusion This method is tend to monitor the density of rodent long＇at the same places.
