中文摘要	运用CoLM(CLM3.0)模式对典型干旱区(张掖站)和青藏高原区(安多站、MS3478站)进行了off-line验证试验,检验了CoLM模式在典型干旱区和青藏高原区的性能.结果表明: CoLM模式对典型干旱区绿洲灌溉农业的陆面过程模拟较好,土壤各层温度的日变化趋势和季节变化趋势都能较准确地模拟出来,模拟的地表温度与观测值相关系数为0.885,均方差为0.873;模拟的5 cm土壤温度值与实测值的相关系数为0.944,均方差为0.891.在高原地区能量平衡分量的模拟中,净辐射、感热模拟效果较好,潜热分量模拟值偏大,故将CoLM模式用于高原地区还有待进一步改进.
英文摘要	A off-line validation experiment is done with common land model (CoLM) at Zhangye station of typical arid region in Northwest China and Anduo and MS3478 stations of Qinghai-Xizang Plateau. The result show that the numerical simulation of land surface process of typical arid region is better by the CoLM. The daily and seasonally changes of vertical profile of soil temperature is exactly simulated, in detail, the correlation coefficient between simulation and observation of ground surface temperature is 0. 885. The standard error is 0. 873 > the correlation coefficient between simulation and observation of the soil temperature at 5 cm depths is 0. 944, the standard error is 0. 891. The simulations of net solar radiation and sense heat flux over Qinghai-Xizang Plateau are better, but the simulated value of latent heat flux is higher, actually, during GAME-Tibet monsoon experiment, the energy imbalance problem has been existed. So, it is not for sure to say that the model’s simulation is not good.
