Abstract:

Based on the review of relevant theories and practices in river conservation and restoration all over the world, the authors proposed that a proper ecological target should be set up to meet the primary need in river conservation and restoration. The target should be quantified for practical direction for river management and restoration. For this purpose, a recently developed method of DRIFT is briefly introduced in the paper, and the classification of ecological conservation level or grade was also analyzed. In consideration of the present situation in China, it is suggested that we should make out the ecological functional division of rivers,plan and set various conservation targets for different rivers,and confirm corresponding conservation levels so as to enforce river conservation and restoration.

Key words: conservation and restoration, ecological target, quantification, river
