摘要: 为了提高预测稻瘿蚊发生量的准确度,有效防控稻瘿蚊虫害成灾面积,采用基于K近邻样本拟合相对误差绝对值与时序相关系数最小原则优化的BP神经网络预测模型REMCC-BPNN,选取广为认可的气温和降水量为影响因子,对稻瘿蚊的发生量进行独立预测。通过2个实例(化州市晚稻稻瘿蚊发生程度和广西邕宁县稻瘿蚊发生程度)验证显示:REMCC-BPNN模型的独立预测精度分别为94%和100%,明显优于经典回归分析、SVR-CAR、MIV-BPNN等参比模型。可见,REMCC-BPNN模型在虫害发生量预测方面有良好的应用前景。

Abstract: In order to improve the predictive accuracy of the Orseolia oryzae emergency size and control area affected by Orseolia oryzae effectively, an improved Back-propagation Neural Network (BPNN) model named REMCC-BPNN was proposed. REMCC-BPNN optimizes the training model for BPNN based on the minimum correlation coefficient of the absolute value of the K nearest neighbor training samples’ fitting relative error and the K training samples’ time order. This study utilized air temperature and precipitation as influencing factors to forecast pest management independently. The results of two instances (Orseolia oryzae emergency size in Huazhou City and Yongning County of Guangxi Province) indicated that the prediction accuracy of REMCC-BPNN was 94% and 100% respectively, which was better than that of several traditional used models, such as SVR-CAR, MIV-BPNN. REMCC-BPNN has a promising application prospect in the forecast of pest management.
