目的：研究使用２４ｈ弓形夹法和５米夹线法调查鼠类的关系。方法：对察哈尔丘陵、锡林郭勒草原和鄂尔多斯荒漠草原的监测数据，用配对资料的ｘ２校正公式进行比较。结果：在察哈尔丘陵，除四种少见种外，两种方法调查的鼠类是相同的；在锡林郭勒草原和鄂尔多斯荒漠草原，使用５米夹线法捕到的鼠类均在２４ｈ弓形夹法调查的啮齿动物中。结论：在原始面貌未改变地区，可以不做５米夹线法监测；若采用单公顷一日弓形夹法调查黄鼠数量，可以改为使用２４ｈ弓形夹法调查啮齿动物数量。
Objective: To investigate the relationship between the use of 24h bow clip method and 5 m clip line survey of rats. Methods: The monitoring data of Chahar Erh, Xilin Gol Grassland and Erdos Desert Steppe were compared with x2 correction formula of paired data. Results: In Chahar Huron, except for four rare species, the two types of rodents were the same; in the Xilin Gol Grassland and Ordos Desert Grassland, the rats caught by the 5-meter thread-holding method were all in 24h Law investigation of rodents. Conclusion: In the unaltered area, the 5-meter wire-line method can not be used for monitoring. If the number of yellow-haired rats is investigated by single-bow-and-a-single-clip method, the number of rodents can be investigated by using the 24h-clip method.
