Human activities have led to changes in land use, environmental conditions and climate. Land use change has significant impacts on hydrology and other water related problems. In this study, the assessment of land use change is used to explore the effects of human activities on hydrologic response under the paleo-environment and the present conditions by using a grid-based distributed hydrologic model. According to the results of land use change analysis, forest area decreased, but the areas of building types A and B increased from 1843 to 1902. Due to increasing building area and decreasing forest area and rice fields, the peak discharge is increasing and arriving earlier. Projected rainfall-runoff hydrographs suggest that rainfall may peak early (in the third hour) leading to earlier peak discharge or rainfall could peak later (in the eighth hour), leading to larger and later peak discharge. This study offers guidance for future urban planning and flood risk management.
