对油菜的冠层温度特征进行了研究,并在此基础上建立了油菜的冠气温差模型和CWSI模型。利用建立的CWSI模型对植株含水率进行预测,结果表明:油菜含水率预测值与实测值的平均相对误差小于9.2%;CWSI模型能够实现对油菜含水率的定性和定量分析。
It was developed that using rape canopy temperature characteristics to analyze the rape moisture content.Temperature differences between canopy-air model and CWSI model are builded which based on correlativity and action rule.The CWSI model is used to predict the moisture content of rape.The result shows that average relative deviation between the estimated values and the real values less than 9.2%,the CWSI model can be use to qualitative and quantitative analyze the rape moisture content.
