摘要
从亚洲飞蝗在新疆发生基地的生境特点、形成和消退过程,分析亚洲飞蝗灾害发生消退的原因。自然条件变化和人们经济活动常改变亚洲飞蝗发生基地的生态条件及环境,并诱发或抑制飞蝗灾害的发生。文章指出根治亚洲飞蝗灾害的有效途径是贯彻“改治并举、根除蝗害”的方针;加强蝗情监测;适时防治以及通过水利建设和农田开垦,改变飞蝗发生基地的生态条件等。
he paper deals with circumstances of the asiatic migratory locust that occurred during the 1950s to present and analyzes the characteristics of habitat,the changes of natrural condi- tions,the influences on the ecological environment by human activities,and control measures.The main distribution areas of the locust in Xinjiang are the marshes around overflow belt of the preatic water and lakes,and the marshes along wide river valley plain.The rainfall of mountains determines the discharge of river,in turn,influences the water of marsh,ecological environment and the population density of asiatic migratory locust.During the drought year,or the following one or two years,the harmfulness of locust will be very serious.On the other hand,through the reclaimation for farming and water conservancy construction,which change the ecological habitat,will have different results,that is to say,it maybe of benefit or harmful to the locust.The effective measures of administering the pest problem are to carry out the guiding principle“reform and control simultaneously”,strengthen prediction,control the locust timely change ecological habitat of the locust outbreak center by water conservancy Construction.
