麦蚜种群动态的模糊聚类分析
0
()
摘要:
采用模糊聚类分析方法对麦蚜种群动态进行分析,揭示出麦蚜种群的发生规律及特点。其种群动态有5个状态集。在麦蚜防治中,应注意发生盛期A_2的种群动态。当种群发展到A_4′状态时,种群将自然下降。

()
Abstract:
The occurrence charcteristics of Rhopalosiphum padi Linn. populationwas studied by the method of Fuzzy cluster analysis. The populationdynamics was divided into 5 state combinations. In the process of controllingRhopalosiphum padi,high level population in state of A_2 should be paidattentionto. In the state of A_4, population will decline.
