Application of Grey Clustering Method in Eutrophication Evaluation of Wetland
نویسندگان
چکیده
Grey clustering method is applies to evaluate the water eutrophication of wetland, in order to propose a superior evaluation system which is suitable for wetland eutrophication assessment. Eutrophication degree is divided into 6 classifications, and threshold of each classification makes reference to eutrophication standard of Chinese lake and eutrophication characteristics of wetland. Whitenization weight function is used to describe the limit of eutrophication classification, and clustering weight is selected correctly. Finally, based on grey theory,a mathematical model for evaluating water eutrophication of wetland is proposed. The application of this method to evaluate the water eutrophication in Zhalong Wetland is given as an example for demonstration. It proves clustering model proposed is exact, comparable and applied.
