摘　　要：草原虫害的爆发严重威胁草原生态系统的安全,草原虫害的发生趋势预测及防治工作在保护草原生态系统方面具有重要性意义。本文通过统计分析红原县2013~2021年草原虫害发生情况及其与环境温度的相关性,结果发现:红原县草原虫害年平均发生面积为6.59×10^(4)hm^(2),年平均严重危害面积2.86×10^(4)hm^(2)。其中土蝗年平均危害面积为2.41×10^(4)hm^(2),年平均严重危害面积为1.23×10^(4)hm^(2);草原毛虫年平均危害面积为4.04×10^(4)hm^(2),年平均严重危害面积为1.45×10^(4)hm^(2);其他害虫年平均危害面积为0.16×10^(4)hm^(2),年平均严重危害面积为0.03×10^(4)hm^(2);红原县2013~2021年间累计防治1.08×105hm^(2)。此外,草原害虫发生面积随温度的增加呈增加的趋势,但相关性不显著。本文的结果为草原虫害的发生机制提供参考。The outbreak of grassland pests seriously threatens the safety of grassland ecosystem,and the occurrence trend prediction and control of grassland pests are important in the protection of grassland ecosystem.Through statistical analysis of the occurrence of grassland pests in Hongyuan County from 2013 to 2021,the results found that the average annual occurrence area of grassland pests in Hongyuan County was 6.59×10^(4) hm^(2),and the annual average serious harm area was 2.86×10^(4) hm^(2).The annual average hazard area of soil locusts is 2.41×10^(4) hm^(2),and the annual average serious harm area was 1.23×10^(4) hm^(2).The average annual mean hazard area of grassland caterpillars was 4.04×10^(4) hm^(2),and the average annual serious harm area was 1.45×10^(4) hm^(2).The average annual hazard area of other pests was1600hm^(2),and the average annual serious hazard area was 300hm^(2),and accumulated 1.08×105 hm^(2).In addition,the occurrence area of grassland pests increased with temperature,but the correlation was not significant.The results of this paper provide a reference for the occurrence mechanism of grassland insect pests.
