| 摘 要： | 在对冬小麦单产农业气象预测方法研究中，将空间插值技术应用到单产预测中，即对降水量、温度等农业气象因子进行空间插值。不仅将单产预测区域的气象因子从点数据插值成面数据，而且解决了单产预测中农业气象模型空间外推问题，从而提高了冬小麦单产预测的精度，具有一定的实用性。

| Abstract: | The spatial interpolation technology was applied on forecasting winter wheat yield in the study of agro-meteorology forecasting.That was to say,spatial interpolation of agro-meteorology factors included precipitation and temperature.This technology not only interpolated the regional meteorological factors from point data into polygon data,but also solved the spatial extrapolation of agro-meteorology model in yield forecasting.As a result,the study could improve the precision of forecasting winter wheat yield and had some practicability. |
