摘要
分析了博斯腾湖周边亚洲飞蝗的生物学特性和生存环境,研究了与之相关的气候条件。结果表明,开都河(博斯腾湖的入湖水系)上游山区降水和焉耆盆地5月份气温是影响飞蝗大暴发的主要气候因素。山区年降水量在一定范围内连续3年呈V型波动,且第3年5月份湖区气温正常(无极端低温)是飞蝗大暴发的气候成因。
The biological characteristic and living conditions of Asiatic migratory locust around Bosteng lake are analyzed and the related climatic conditions are studied. The result shows that the precipitation in mountain area in the upper reaches of Kaidu river （entering water system of Bosteng lake） and the air temperature in May in Yanqi Basin are the main climatic factors of locust firestorm. V-type fluctuation of annual precipitation in the mountain area for three years in some range and the normal air temperature in May of the third year in the area round Bosteng lake （without extreme low temperature） are the climatic causes of locusts firestorm.
