应用灰色系统灾变预测理论对汾阳市历年玉米叶螨发生量数据进行处理,建立了吕梁市玉米叶螨发生量灰色系统GM(1,1)灾变长期预测模型X=194.764 71 e0.08508(k-1)-183.764 71。经精度检验,回测值与实测值(统计值)完全吻合。
The gray system catastrophe prediction theory was used to deal with the occurrence data of maize spider mites in Fenyang City. The GM (1,1) catastrophe long-term prediction model of maize spider mites occurrence in Luliang City was established. X = 194.764 71 e0.08508 (k -1) -183.764 71. The accuracy test, back to the measured value and the measured value (statistics) exactly match.
