摘　　要：草原虫害发生流行是造成草地生态系统恶化的一个主要原因,同时也是草场生产经营过程中比较容易出现的一种自然灾害。近年,生态环境保护日趋严峻,国家大力倡导绿色环保理念,致力于对生态环境有效治理。草原害虫的发生,通常和不科学的草原利用、草原管理有密切联系。由于受到不科学放牧、干旱、草地植被退化及沙漠化等多方面因素影响,使草场生态功能逐渐减弱,抵抗能力逐渐变差,给草原害虫繁殖生长提供条件,造成草原害虫大规模发生流行。该文主要结合内蒙古化德县草原害虫发生现状,论述草原虫害生态治理措施。The prevalence of grassland pests is one of the main reasons for the deterioration of grassland ecosystem,and it is also a kind of natural disaster in the process of grassland production and management.In recent years,eco-environmental protection is becoming more and more severe.The state advocates the concept of green environmental protection and devotes itself to the effective management of eco-environment.The occurrence of grassland pests is usually closely related to unscientific grassland utilization and grassland management.As a result of unscientific grazing,drought,grassland vegetation degradation and desertification and other factors,the ecological function of the grassland gradually weakened,the resistance gradually became worse,providing conditions for the reproduction and growth of grassland pests,causing an epidemic of grassland pests.This paper mainly discusses the ecological control measures of grassland insect pests in Huade county,Inner Mongolia.
