- More population and less land is the main contradiction in the process of urbanization in China. Residential buildings developing upward and downward, such as the underground structure, not only made the impervious surface area increased, increasing more surface runoff, but also the underground impervious area increased, jointly cutting the connection between the rainfall infiltration and groundwater recharge and further reducing groundwater recharge and enhancing the heat island effect of the city. A case study of the construction of Jinan urban district puts forward the concept of underground impervious rate, evaluated effect of underground impervious rate on recharge of karst groundwater, analyzed the relationship between the actual impervious surface rate, calculating impervious surface rate and runoff. The result shows the impervious area after construction is an important factor which causes 93% of the loss of surface water recharging into karst groundwater compared with before construction. Finally, the concept of construction and development of water ecological community in Jinan was proposed according to the special geographical features and the construction of the pilot project of the sponge city in Jinan.
