The change of land utilization type caused by human activities such as the urbanization is one of major content in urban ecology study. Urban hydrology effect created by the urbanization process just belongs to its significant study fields. According to the introduction to urbanization essence and new research progress of urbanization hydrological effects in China and other countries, this paper firstly summarized the main study direction and content of urban hydrology effect, specifically including utilization’s impact on various hydrologic features and water quality, secondly made conclusions on study methods of urbanization hydrological effects which are the method of basin contrast experiment, the method of hydrology characteristic parameter and watershed hydrological model, and thirdly clearly showed problems and shortages in study of urbanization hydrological effects, and finally speculated on the future study trends.
