摘要
应用模糊聚类分析理论和方法 ,对武进市 1995年、1996年小麦纹枯病的发生流行动态进行预报。选取分辨力较高的聚类指标 ,截取λ=0 .6 ,可分 3类。对预测结果与实况对照进行比较 。
This paper forecasted the occurrence and epidemic dynamics of wheat sharp eyespot in Wujin by using the theories and methods of fuzzy cluster analysis from 1995～1996 Cluster indices with higher resolving power were selected and λ=0 6 was intercepted,then the epidemic dynamics of the disease could be divided into 3 types.It was proved according to the comparison between forecast and reality that the epidemic year type analyzed by means of fuzzy cluster was identical with the experiential year type.
