两种鼠密度监测仪应用比较

A comparison between two types of rodent-density-surveillance instruments in application

目的探讨2种鼠密度监测仪在鼠类监测中的优缺点。方法在可能有鼠类活动的地方布放鼠密度监测仪,监测鼠类活动。结果 2种鼠密度监测仪均可拍到了鼠类的活动照片或视频。结论 2种红外感应相机均能监测到鼠类活动。视频包含信息量大于照片的信息量,可以了解更多的鼠类生态习性、活动规律。该设备可以用于鼠密度监测。

Objective To explore the advantages and disadvantages of the two types of rodent - density - surveil- lance instruments in rodent surveillance. Methods Rodent-density-surveillance instruments were placed in the possible places to surveillance the activities of rodent. Results The photo and video concerning rodent activities were observed by these two types of instruments. Conclusion Both the two infrared sensor camera could be able to surveillance the rodent activities. The information reflected by the video is more than the information reflected by the photo, and contains more information about rodent habits and activity patterns. The instrument can be used in the ro- dent density surveillance.
