摘要:
利用大田实测数据对ORYZA2000模型中的辐射模块进行了评估与改进。结果表明:水稻产量和地上部分干质量对散射辐射比例变化敏感。但是模型模拟的1 d不同时刻太阳辐射中散射辐射比例与实测值相比存在较大误差,傍晚时刻的均方根误差可达0.15。而该模拟偏差(模拟值与观测值的差值)与大气透射系数呈二次曲线的关系,利用模拟偏差与大气透射系数之间的关系改进了模型对散射辐射比例的模拟。改进的辐射模块对1 d 3个时刻散射辐射比例模拟的均方根误差分别缩小了0.01、0.02和0.02。该结果可为ORYZA2000模型的改进提供参考。
Abstract:
The radiation module in model ORYZA2000 for rice yield simulation was assessed and improved using the observed data. The results showed that rice yield and above-ground dry weight were sensitive to the changes of diffuse radiation fraction in global solar radiation. Big errors between simulated value of diffuse radiation fraction and observed value were found in different time points of a day; the root mean square error even reached 0.15 in late afternoon. A quadratic relationship between the difference of simulated value and observed value and the atomospheric transmission coefficient improve the simulation of radiation module. The root mean square error of diffuse radiation fraction simulated by the improved model was decreased by 0.01, 0.02, and 0.02 in three time points of a day, respectively.
