马尾松毛虫的电子计算技术的定量测报,在我国还刚开始。本文应用二次判别分析,通过数字电子计算机对马尾松毛虫发生量和各种气象因子的相互关系进行分析。根据电算程序中的筛选标准自动筛选出影响马尾松毛虫发生的主要气象因子所组建的判别函数式,可作为测报数学模式。并据此测报出未来马尾松毛虫的发生量(共分为发生极轻,发生轻、发生重,发生极重四个量极)。判别分析电算定量测报方法应用于福建省连江县和浙江安吉县。
Masson pine caterpillar quantitative calculation of electronic technology, has just begun in China. In this paper, by using the second order discriminant analysis, the relationship between the amount of Dendrolimus punctatus and various meteorological factors was analyzed by digital electronic computer. According to the screening standard in the computer program, the discriminant function which is formed by the main meteorological factors affecting the occurrence of Dendrolimus punctatus was automatically screened, which could be used as the mathematical model of the report. According to this, we measured the amount of Dendrolimus punctatus in the future (divided into extremely light, mild, heavy, and extremely heavy). Discriminant Analysis The computerized quantitative forecasting method is applied to Lianjiang County, Fujian Province and Anji County, Zhejiang Province.
