中文摘要：

一个分布式的福雷斯特沼泽地 Hydrologic 模型(DFWHM ) 被构造并且过去常在三个不同分水岭(一个冷区域，一个亚回归线区域，和一个大规模分水岭) 的不同气候检验水动力学。一个 phenological 索引被用来代表季节并且当雪收拾行李的过程，结冰的土壤，和雪并且冰融化也在模拟被包括时，种类树华盖变化。在冷区域，在冬季的地下水水平的模仿的秋天与观察数据由于土壤由于融化的雪和冰在春天结冰和上升作比较很好。因为表面水和地下水的土壤水分蒸发蒸腾损失总量和相互作用在模型被包括，在亚回归线区域的地下水水平的建模的季节的趋势与观察一致。在建模并且观察的自记水位计之间的比较显示在大规模分水岭的模拟设法在不饱和、浸透的地区捕获水动力学。

英文摘要：

A Distributed Forest Wetland Hydrologic Model （DFWHM） was constructed and used to examine water dynamics in the different climates of three different watersheds （a cold region, a sub-tropic region, and a large-scale watershed）. A phenological index was used to represent the seasonal and species changes of the tree canopy while processes of snow packing, soil freezing, and snow and ice thawing were also included in the simulation. In the cold region, the simulated fall of the groundwater level in winter due to soil f~eezing and rise in spring due to snow and ice melting compare well with the observed data. Because the evapotranspiration and interaction of surface water and groundwater are included in the model, the modeled seasonal trend of the groundwater level in the sub-tropic region is in agreement with observations. The comparison between modeled and observed hydrographs indicates that the simulations in the large-scale watershed managed to capture the water dynamics in unsaturated and saturatedzones.
