Preliminary measures to restore aquatic ecological environment of Fuhe River Basin;

The assessment index system of aquatic ecological environment in Bengbu is built based on the essence of society-economy-nature of aquatic ecological environment.

So studying on the aquatic ecological environment of the subsi.

Using remote sensing (RS) data and field investigation results, the water eco-environment was analyzed in mid-eastern China.

Urbanization is the necessary course of the soc iety development, but in this course the interference of the human activity to t he nature often causes water problems such as flood overflows, water resource is deficient and water eco-environment deteriorates etc.

Using a modified method of Index of Water Supply and Demand(IWSD),this paper studies the transitional track of water ecosystem in the Hai River Basin from1960to2030.

Using diverse methods to estimate the economic losses caused by water ecosystem deterioration in the Hai River Basin and referencing the foregoing studies,this paper concludes the economic losses ranged from 0.
