Studies On The Paving Environment Design In Urban Public Space From View Of The Ecological Significance

Urban construction not only creates the human daily life, but also changes the nature ecology environment. In the city construction, the square, the path take larger size, the permeability correspondingly is weaken; the urbanized area hot island effect; the rain island effect also gradually is revealed. The city draining water pipe network burden is overweight; the natural ecosystem balance is out of balance; the recourse waste is more serious and plant and soil living conditions has also been destructed. The city ecology environment turning worse put forward more and more ecosystem design questions.Hard pavement in the city public space although has many negative effects to the ecological environment; well it is not right to consider it unreasonable and useless. It has positive effects for the city sustainable development and the improvement of the city ecosystem. Therefore it has to be designed ecologically when being applied to the city construction. It is widely researched and confirmed that ecological effects of water permeability. It can alleviate city of stingy wait a problem, accumulate a water problem and resolve rain water to make use of again a problem through the oneself improvement road noodles. But using deeply water to spread to pack isn't enough,The paper researches about the method of pavement design in the city public opening space in the view of ecology raises the design principles. There are examples combined with the paper to analyze the pavement design, which is expected meaningful for human.
