摘要
以柑桔潜叶蛾 9个世代的生命表资料和稻纵卷叶螟 6个世代的生命表资料作为例证研究 ,首次将灰色系统理论中的斜率关联度分析法 ,应用于昆虫生命表关键因子的确定 ,收到了理想的效果。作为一种简便、科学、可靠的量化方法 ,在正确地判明关键因子的同时 ,还向我们提供了各亚致死力按其作用强度大小排序的有用信息 ,可在生命表研究中推广应用。
In this paper, by using life table materials of 9 generations of Phyllocnistis citrella and of 6 generations of Cnaphalocrocis medinalis as example illustrations, the optimal results were obtained when the slope association analysis method in gray system theory was applied on key factors ascertainment in life table of insect for the first time. The slope association analysis method was of a handy, scientific and reliable quantization method and ascertained the key factors correctly; meanwhile, it provided us with serviceable information of each sub lethal force arranged in order according to the action intensity and may be spread in life table researches.
