摘　　要：概述了我国蝗虫灾害气象环境成因方面的研究成果,包括气象环境条件对蝗虫发生、分布和群落组成等的影响,以及蝗虫的发生与气象条件和气候异常的关系。结果表明蝗虫的发生时期和世代及蝗卵能否顺利孵化主要是由气象环境决定的;气象环境条件的空间分异及随年度、季节的演替可能引起蝗虫发生程度的区域分布差异以及群落组成成分在年度、季节间的波动;温度和降水是影响蝗虫发生消长的主要气象要素,气候异常可导致蝗虫大发生。This paper simply summarizes the research achievements in the aspect of meteorological environment affecting the disaster caused by locusts, which include the effects of meteorological environment on the occurrence and distribution of locusts, the relation between locusts occurrence and meteorological condition as well as the relation between the occurrence and abnormal climate. The results show that the occurrence date, generations in a year and whether locusts eggs can incubate successfully are mainly determined by meteorological condition. The spatial distribution and the variation of meteorological condition with year and season may cause different occurrence degree in different region and member fluctuation of locust community within different year and season. Temperature and precipitation are key factors that affect the arising and decline of locusts. Abnormal climate can bring severe locust plague.
