摘要:

利用灰色关联分析法与相关分析法,分别确定与昭苏县油菜普花期关联最大的物候期和显著相关的气象因子,利用昭苏县1990—2019年物候期和气象因子分别建立回归模型,预测2020—2022年的普花期,利用均方误差和相对误差对模型的拟合结果进行评价,利用平均拟合精度对模型的预测结果进行评价。结果表明,基于昭苏油菜物候期的回归模型、基于昭苏气象因子的回归模型拟合结果相对误差分别为0.72%、2.59%,均方误差分别为2.6、6.0,预测结果平均拟合精度分别为98.9%、91.7%,基于物候期建立的昭苏油菜普花期回归模型预测结果更精准。

Abstract:

In this study, gray correlation analysis and correlation analysis were used to identify the most correlated phenological period and significantly correlated meteorological factors for the blooming period of oilseed rape in Zhaosu county, respectively. A regression model was developed using data on phenology and meteorological factors from 1990 to 2019 in Zhaosu county to predict the blooming period in 2020 to 2022. In addition, the mean square error and relative error were used to evaluate the fitting results of the model. Finally, the prediction results of the model were evaluated using the mean fitting accuracy. The results showed that the relative errors of the regression model based on phenological period of oilseed rape in Zhaosu county and the regression model based on meteorological factors in Zhaosu county were 0.72% and 2.59%, respectively, the mean squared errors were 2.6 and 6.0, respectively, and the average fitting accuracy of the prediction results were 98.9% and 91.7%, respectively. A comparison of the two models revealed that the regression model of oilseed rape blooming period in Zhaosu county based on the phenological period was more accurate in model prediction.
