| 摘 要： | 利用ＩＡＰ９４陆面过程模式对淮河流域不同季节（春、夏、秋）、不同下垫面（旱地、森林、水田）进行了单点数值模拟试验，结果表明ＩＡＰ９４不但能较好地模拟出观测的地气间各种能量通量以及植被的冠层温度，同时还很好地模拟出整层土壤含水量的变化趋势，从而证实了ＩＡＰ９４陆面过程模式具有正确描述东亚半湿润季风区陆气相互作用的能力。另外比较结果还揭示了水田表面强烈蒸发作用的重要性，需要在陆过程模式中予以重视。

| Abstract: | Off-line experiments have been conducted with IAP94 land surface model on different surface types (cropland, forest and paddy field) in different seasons (spring, summer and autumn) over the Huaihe River basin. The simulated energy fluxes and canopy temperature by IAP94 agree quite well with the observations,simulation results also show that IAP94 can successfully simulate the tendency of total soil water content variation. The comparison results between simulation and observation indicate that strong evaporation at the paddy field in summer should be paid more attention to within the land surface models, and model s performance leads to the conclusion that IAP94 is capable of reproducing the main physical mechanisms governing the land-surface processes in the East Asian semi-humid monsoon region. |
