摘要
本文应用模糊聚类分析方法对稻粉虱Aleurooybotus indicus David of Subramanias种群系统动态进行模糊聚类分析,模糊聚类分析结果表明,在置信水平0.9640≤λi<0.9880的情况下,该种群系统分为6个亚系统:SS1、SS2、SS3、SS4、SS5和SS6。文中对各个亚系统的动态规律进行特征描述,以期为稻粉虱的综合防治提供理论依据。
Population system dynamics of Aleurooybotus indicus David et Subramanias were analysed with fuzzy cluster theory. It indicated that the populalion system could be divided into six subsystems:SSI ,SS2,SS3 SS4 SS5 and SS6 if the degree of confidence was 0. 9640(?) (?)(?) 0. 9880. Dynamic properties of the subsystems v/ere characterized respectively as to provide sci-entific basis for the controlling of Rice Whiteflies.
