Research on the water ecological planning for city environmental system

The aims,principles and requirements of the water ecological planning for city environmental system are analyzed and the ways of water eco-structure designing for cities' environment are discussed in this paper.By applying the ecological theory and methods and studying planning of the eco-function and eco-analysis,the environmental water in cities is planned with the macroscopic and microcosmic view,on the basic of maintaining the balance and intactness of the eco-system on considering the geological locations,the different requirements of function,the different ways of applications,the different development potatials of the environment water.The structure designing of the eco-system makes the ecological functions and aims of environment water in cities come true and establisles a complete and sustainable water eco-system.
