摘　　要：草原鼠害的发生与栖息地气候变化有密切联系。将2009—2019年内蒙古自治区兴安盟科尔沁右翼前旗草原鼠害发生面积与气象数据进行Pearson相关性分析,得到与发生面积具有显著相关性的3个气象因子:温度、风速、降水;发现与草原鼠害发生有着显著的相关性的有:上年10月下旬、11月上旬、12月上旬,当年1月下旬、2月下旬、3月上旬、5月中旬、7月下旬的最大风速;当年4月下旬的降水量;当年3月下旬、4月下旬、5月下旬、6月下旬、7月中旬的最低气温。通过相关分析,以期为科尔沁右翼前旗的草原鼠害防治提供参考。The occurrence of grassland rodents is closely related to the climate change of habitat.Based on the Pearson correlation analysis of grassland rodent area and meteorological data in Horqin Right Front Banner of Hinggan League of Inner Mongolia from 2009 to 2019,three meteorological factors closely related to the area were obtained:temperature,wind speed and precipitation,the results showed that the maximum wind speed in late October,early November,early December of last year,late January,late February,early March,middle May and late July of that year had significant correlation with the occurrence of grassland rodent;The precipitation in the last ten days of April of that year;The lowest temperature in late March,late April,late May,late June and mid July.Hope that through these analysis,we can provide reference for the grassland rodent control in Horqin Right Front Banner.
