| 摘要: |
| 根据宁夏吴忠春小麦田和甘肃省民勤县棉花田的实测资料，对估算农田土壤水分状况的冠层温度模型进行了研究。结果表明采用冠层温度与气温差（Tc-Ta）可较好地用于估算土壤含水量，引入其他气象参数后模型的精度没有明显改进。 |

| Abstract: |
| Based on the field experiment of spring wheat at Wuzhong,Ningxia Hui Autonomous Region,and cotton at Minqin county,Gansu Province,several models of using canopy temperature to estimate soil water content were studied.The results showed that soil water content can be estimated successfully by using canopy-minus-air temperature,but when other meteorological factors were introduced into the models,there was no much change in the accuracy of the models. |
| Key words: infrared canopy temperature,canopy-air temperature difference, soil water content |
