摘要
综述了受都市化影响的小流域水文特征和研究途径。通过实际观测和概化模型试验,提出了反映都市化水文效应的指标,即当不透水面积比超过20％时,都市化影响表现明显。最后介绍了都市化影响的小流域雨洪计算方法。
The influences of urbanization on hydrological regimes in a sman watershed and their research approaches are reviewed. Based on the data from field observations and laboratorial modelling experiments, an index reflecting hydrologic effects due to urbanization is proposed, that is, the influences of urbanization are considered to be substantial if the impermeable area is over 20% of total catchment area. Also, the estimating method for storm floods in an small watershed due to urbanization is introduced.
