Cobble weakens impulsive force.
Accumulating too many rainwater in place however, being preset when the circular Rain Garden, soil is difficult to receive ponding for the moment,
Air can not based on sponge city ecologic rainwater garden and wrap the soil in the ecologic rainwater garden based on sponge city
Between circulate, be easy to cause rotten of plant, and if no rainfall is also needed to manually pouring the plant in greenbelt for a long time
Water, waste of manpower cost are had no idea to realize and are efficiently used to rainwater.
On December 12nd, 2013, the Xi Jinping General Secretary exists《Central urbanization working conference》Speech in emphasize：" promote city
It to pay the utmost attention to limited rainwater to stay when city's drainage system, pay the utmost attention to that elements is more utilized to drain, build certainly
So stockpile, naturally osmotic, self-purification sponge city ", that is, wish city can as sponge, adapt to environmental change and
Coping with natural calamity etc. has good " elasticity ", water suction, water storage, infiltration, water purification when rainy, will be stored when needing
Water " release " is simultaneously used, to promote urban ecological system function and reduce the generation of Urban Flood Waterlogging.
It is of great significance based on Rain Garden to improving the ecological environment, being promoted city taste and promote economic development, because
This, designs a kind of ecologic rainwater garden based on sponge city, good life recreation space is provided to citizen, to urban rainwater
It recycles and ecology improvement is all of great advantage, to realizing Ecological Sustainable Development, there is important application value.
