| 摘 要： | 以35个实验小区，8个生育期的冬小麦田间测量冠层反射高光谱组成三维数据信息阵，采用多维偏最小二乘(multiway partial least squares, NPLS)算法建立了冬小麦亩产量估产模型。模型用于对13个实验小区产量预测分析，预测值与实际值的相关系数ｒ为0.936 6， 平均相对误差为4.44%，说明模型的预测效果较好，对实际的估产工作有一定的指导意义。 |

| Abstract: | The present study piled a cube array with the winter wheat's cap reflection hyperspectra sampled from 35 experimental districts during 8 growth periods,and then used a multiway partial least squares(NPLS) algorithm to establish a model to(assess) the per-mu-yield of winter wheat.The model was used to predict the per-mu-yields of other 13 experimental districts.The correlation coefficient of predicted and actual values was 0.936 6,and the mean relative error was 4.44%.These results showed a good prediction of the model.The study has guiding meaning to actual yield assessment. |
| Keywords: | Three-dimensional hyperspectrum NPLS model Product assessment of winter wheat |
