摘要
利用 195 3~ 2 0 0 0年河南省东亚飞蝗的发生时间序列资料 ,做了飞蝗大发生年的游程检验 ,结果表明 ,195 3~ 2 0 0 0年间河南省东亚飞蝗的大发生年是随机出现的。
By using time-sequence data of the outbreaks of the oriental migratory locust in Henan Province from 1953 to 2000, a random walk was done to the year of the pest outbreaks. The result shows that the years of outbreak locust in Henan Province from 1953 to 2000 appeared at random.
