Assessment of urban wetland based on 3r framework

An assessment indictor system for management of urban wetland is established in this paper, based on the Research - Restoration - Recreation framework, which can denote the relationships between the ecological functions and the wetland healthy state. Then with the weight of each indicator decided by analytic hierarchy process, a fuzzy pattern recognition model is employed to evaluate the wetland health. Furthermore, according to the choice principles and five-grade assessment standard, the state of Qinhuai River Wetland in Nanjing and Xixi Wetland in Hangzhou are assessed. The assessment result proves that this indicator is feasible.
