摘  要:
依据云南省马龙地区2003~2012年种植季的数据资料,分别利用单一回归模型、混合模型建立预报模型,并利用历史数据资料的回代进行精度检验。结果表明:2个模型均满足精度要求,但经过改进的混合模型明显提高了拟合精度。采用混合预报模型替代传统单一预报模型,综合考虑了同时期和不同时期的因素对马铃薯晚疫病的影响,提高了模型的精度。

摘  要:
According to data of planting season in Malong region during 2003- 2012,respectively by using single regression model and hybrid model,forecast model was established,the accuracy test was conducted on historical data back generation. The results showed that the two model can satisfy the requirements of accuracy,but the improved hybrid model,the fitting precision is obviously improved. Using mixed forecasting model to replace traditional single forecast model,considering the influence of factors at the same time and different time on the potato late blight,the accuracy of the model is improved.
