Abstract

Abstract: Wetland is one of the most important ecosystems in the world,due to the adverse effects of environment pollution,excessive reclamation and illegal enclosure,wetland resources are confronted with extreme threats.This paper preliminarily inquiries into the general approach and technical method of international important wetlands quality evaluation through constructing evaluation index system based on natural elements and human activities and calculating evaluation index weight by utilizing analytic hierarchy process and Delphi method.Taking East Dongting Lake as an example to verify the quality evaluation method,the result indicates that it is feasible and it can provide scientific references to the protection,management and capacity-building of fulfilling agreements of international important wetlands.

Key words: wetland resources;quality evaluation;natural elements;human activities
