摘要：

Global climate change and human activities (land use change) have great effect on the hydrological circle. Land-use change has direct effect on hydrologic processes through its link with the evapotranspiration regime on one hand and sometimes extreme change in surface runoff on the other hand. MIKESHE software developed by DHI is used to establish surface water and ground water coupling model of Skjern catchment, standard parameterization and calibration of the model has been done. It is utilized to evaluate hydrologic impacts of land use changes in a watershed. The effects of land use changes were analyzed to quantitatively evaluate on watershed hydrology. The results show that the land use change may effect the water balance, especially evapor transpiration. Compared with the original model, the runoff has peak time-lags, the peak flow delays 1 day in both wet and dry year.
