An Evaluation of Urban Artificial Wetland Landscape Proposal Based on AHP-TOPSIS

摘要

The urban artificial wetland is an important component of an urban green space system,and the adoption of quantitative method for studying the evaluation of urban wetland landscape proposal is of great significance to promote the construction of urban artificial wetland.In this study,the evaluation system of urban artificial wetland landscape proposal was established by selecting 6 indicators such as technology,bio-diversity,landscape function,maintenance,construction cost and artistic effect,and adopting the methods of Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS),and empirical evaluations of 30 urban artificial wetland landscape proposals have been conducted to verify the feasibility of the model.The results showed that: AHP-TOPSIS model was applied to the evaluation of urban artificial wetland landscape proposal with a good differentiation degree,which can be used for a comprehensive,reasonable and accurate assessment on the comprehensive quality of an urban artificial wetland landscape proposal as a simple and effective evaluation method.This method also can be applied to evaluation and classification on landscape proposals of other types of green space.
