摘 要: | 用因子权重系数构成模糊向量,用列联表中的列联比构成模糊矩阵,采用模型预测早稻白背飞虱主害代发生量。结果表明:该法回报准确率达100%,对1993年发生量进行预测,预报与发生实况完全相符。

Abstract: | Fuzzy vector was composed of factor weight coefficient. Fuzzy matrix wascomposed of the contingency ratesof contingency table . model was employed to foreeastoeeurrence quantity of main injurious generation of generation of Sogatella furcifera in early rice. The resultsshowed that historical coincidence rate was 100%, Prognosis with this method in 1993 was completely coincident with occurrence. |
