On Eco-hydrology,A New Interdisciplinary Field of Coping the Environment Crisis;

Overview on application of fractal theory to eco-hydrology

The reasonable allocation of water resources in inland water basin should be based on the principle of eco-hydrology, since the transformation of surface water and ground water for many times in a year, and the ecology system is controlled completely by water.

Now the ecohydrology has been paid great attention in academic circles in China, but the research is just on its beginning stage.

A core content of ecohydrology is the study of ecohydrolo gical processes under multiple temporal and spatial scales and under various env ironmental conditions.

Ecohydrology has experienced considerable development since the original conception was promoted by Ingram HAP in 1987.

Based on the development background of eco hydrology, several considerations of eco hydrological concept are introduced, and the framework and system of eco hydrology are given.

Eco hydrology focuses on studing the relationship between vegetation and water under various environmental conditions and revealing the eco hydrological processes of different plants.

In addition,the paper discusses basic research contents of the eco hydrology,and puts forward main eco hydrological problems which have threatened human life.
