The level of science and technology increase types of paving materials continuously enriched, the ecological environment-friendly pavement material new. Ecological permeable pavement including permeable asphalt pavement, pavement of water-permeable concrete and permeable brick. China's traditional for garden pavement pebble pavement is a kind of permeable pavement. Ecological permeable pavement due to its good environmental benefits more and more attention. Ecological permeable pavement function mainly has the following several points.
First of all, the ecological permeable pavement to protect groundwater resources. Ecological permeable pavement by itself and the seepage path of pavement under cushion communicated will direct infiltration of rainwater into the soil in the lower part, can effectively alleviate the negative effects of city of impermeable ground for city water resources. Secondly, ecological permeable pavement is favorable to improve the growth environment of dry. Water permeability and moisture ecological permeable pavement has good, improve soil water holding capacity, reduce soil temperature, increase utilization rate of soil nutrients, the effective protection of the ground under the animals and plants and microorganisms living space, so it is a good example of the "symbiosis with the environment sustainable development idea. Thirdly, the ecological permeable pavement can adjust the ground temperature. Ecological permeable pavement with porous structure, its a series with the outside air and lower permeable cushion connected after rain the sky looks blue. Later, layer under the water by solar radiation, evaporation, so that the surface temperature is reduced, to adjust the role of ground temperature, thereby effectively relieve the heat island effect. "". Finally, the ecological permeable pavement has the role of city waterlogging. Ecological permeable pavement surface due to permeability good, can release flood waters pressure effectively ease the city drainage system, especially for this kind of frequent flood coastal city, has a positive meaning.
In the landscape design, pavement landscape is a part can not be ignored in the whole image to create space, has the extremely important influence. In our garden pavement pay enough attention, reasonable design using a variety of art practices at the same time, also pay more attention to the ecological effects of landscape paving, achieve the perfect combination of functional, artistic and ecological, maximize the use of space landscape resources.
