摘　　要：在城市道路和住宅小区的路面上,若采用透水性铺装构件,可以达到蓄渗雨水、回补地下水、涵养本地水源的目的。空洞率高的构件还可以保持铺装前的地面透水性。若在构件的空洞中植草,则可以增加城市的绿化面积、降低地表温度、提高空气湿度、净化水质。这对改善人居环境、提高空气质量、保护环境和维持生态平衡都有着重要作用。Water penetration pavement component can be used in the road surface of urban areas and residential area for storing rainwater infiltration, recovering groundwater and conserving local water source. Pavement component with high porosity will not reduce the water permeability of road surface. If grass is planted inside the empty holes of the components, the green area of the city can he increased, the surface temperature of the road can be reduced, air humidity can be increased and the water can be purified. So the permeable pavement component can play an important role in improving the living environment and air quality, protecting the natural environment and maintaining the ecological balance.
