中文摘要	利用NOAH(The Community Noah Land Surface Model)、SHAW(Simultaneous Heat and Water)和CLM(Community Land Model)3个不同的陆面过程模式及兰州大学(Semi-Arid Climate Observatory and Laboratory, SACOL)2007年的观测资料,对黄土高原半干旱区的陆面过程进行了模拟研究。通过与观测值间的对比,考察不同陆面过程模式在半干旱区的适用性。研究结果表明:3个模式在半干旱区的模拟性能有较大差异。其中,CLM模式模拟的20 cm以上的浅层土壤温度最优,SHAW模式模拟的深层土壤温度最优;SHAW模式模拟的土壤含水量与观测值最为接近,而NOAH和CLM模式模拟值有较大偏差;3个模式均能较好地模拟地表反射辐射,其中 SHAW模式模拟值与观测值的偏差最小;对地表长波辐射的模拟,CLM模式的模拟最优;3个模式均能较好地反映感热、潜热通量的变化趋势,其中CLM模式对感热的模拟性能优于其他两个模式,在有降水发生后的湿润条件下,CLM模式对潜热的模拟性能最优,而无降水的干燥条件下,CLM模式的模拟偏差最大,NOAH模式对冬季潜热的模拟最优。总体而言,CLM模式能够更好地再现半干旱区地气之间的相互作用,但模式对土壤含水量及干燥条件下的潜热通量的模拟较差,模式对半干旱区陆气间的水文过程还有待进一步的研究和改进。
英文摘要	Single point simulation experiments have been conducted using NOAH (The Community Noah Land Surface Model), SHAW (simultaneous Heat and Water) and CLM (Community Land Model) respectively. Results are compared with observed data from Semi-Arid Climate Observatory and Laboratory (SACOL) to study the land surface process in the Loess Plateau. The goal of this paper is to evaluate the simulation capability of different models in semi-arid areas by comparing model simulations with observations. The results show large differences in the performance of the three models. For soil temperature at the top 20 cm, the simulation capability of CLM 4.0 is the best, while the performance of SHAW is the best for simulation of temperature in deep soil layers. For soil water content, the simulated results of SHAW are the closest to observed values, while large biases are found in simulations of NOAH and CLM. All the three models can well simulate upward shortwave radiation, and the performance of SHAW is the best. The performance of CLM for upward longwave radiation simulation is the best. All the three models can simulate variations of sensible and latent heat fluxes, and the performance of CLM for sensible heat flux simulation is better than that of NOAH and SHAW. As to latent heat flux, CLM performance is the best under wet condition after precipitation, whereas there are large biases in CLM simulation under dry condition without precipitation. The performance of NOAH for latent heat flux simulation is the best in the winter. Relatively, CLM can better represent the interaction between land and atmosphere in semi-arid areas, but its performance for soil water content and latent heat flux simulation under dry condition is not ideal. Further research and refinement for the hydrological process between land and atmosphere described in CLM is needed in semi-arid areas.
