| 摘 要： | 利用定西综合气象试验站观测的春小麦生育期净辐射和总辐射资料，通过回归分析，发现两者之间存在很好的线性相关、进而建立适宜本地区的用总辐射估算净辐射的经验方程。利用当地的常规气象资料，对推算辐射的ＦＡＯ－ＰＭ法和Ｌ法进行对比分析表明：两种推算方法都能较为准确的推算净辐射，但是必须经过订正，从订正后的拟合误差看，ＦＯＡ－ＰＭ方法优于Ｌｉｎａｃｒｅ方法。

| Abstract: | By regression,we found the relation between net radiation(NR)and general radiation(GR) during the growing period of spring wheat in Dingxi is .So the empirical formula that estimated NR with GR and can be applied in the local region is developed.Meanwhile two results of NR by FAO-PM and Linacre models based on routine meteorological data are analyzed.It shows both models can estimated NR accurately,but must be reduced. FAO-PM model is better than Linacre model through fit error. |
