Theme A: Connecting the Pearl River Delta RegionECOLOGICAL ENVIRONMENTAL BENEFITS OF POROUSPAVEMENT ------AN EXAMPLE OF ECOLOGICALCONCRETE PAVEMENTWANG BO 1 AND GAO JIANMING 21Architectural and civil engineering college of Xiamen University,Xiamen, P.R.C,3610052Material college of Southeast University,Nanging, P.R.C,210096ABSTRACT: The interior framework of the porous pavement is formed by a series of porousstructures connected with the outside air. And at the same time it can meet the requirement ofstrength and durability. With an eye to solve the environmental and ecological defects of thetraditional impermeable pavements, as an example of ecological concrete,this paper introduces thestructure of porous concrete pavement and studies the superiority of porous concrete pavement inecological protection, including such aspects as the improvement on the thermal, sound andluminous environment, the supplement of the urban groundwater, the effective utility of the rainwater, urban flood control in urban areas ,cleansing of sewage and improvement offshore ecology& fishery environments. The Application of porous concrete pavement embodies the regressionof urban pavements. Some advice is also suggested.KEYWORDS: porous pavement, Ecological concrete pavement,ecology environmentalbenefits ,ecological regression1. THE BACKGROUNDOne of important features about urbanization is that impervious pavementsreplace the original natural soil and vegetation. The permeability of natural soiland vegetation has been changed. Urban harden pavement occupies considerablyratio in urban area, so its ecology environmental benefit has an very importanteffect on urban ecological environment. Inner structure of porous pavement has aserious porous frameworks and satisfy the needs of strength and durableproperty . The interior framework of the porous concrete pavement is formed by aseries of porous structures connected with the outside air. And at the same time itcan meet the requirement of strength and durability. [1] [2] Porous pavement issimilar grassland and soil texture because of its good permeability and moistcondition. ,so it gives expression to the ideal of “sympathize with environment”and “ecological regression” awfully.
