Set Pair Analysis Method in Lake’s Eutrophication Assessment Based on Correlation Weight Method


Abstract:
In order to solve the uncertainty of the assessment index,order and the assessment standard of each order of lake’s eutrophication,a method of set pair analysis was adopted in the assessment of lake’s eutrophication in this study.Correlation theory of statistics was used in this model for lake’s eutrophication assessment.The weight of each water quality index was calculated according to the correlation coefficient between each water quality index and chlorophyll.this method only suits the lakes of phytoplankton type.By compared with fuzzy assessment method and grey assessment method using measured data in 5 lakes in China,the method is validated to be simple and practical with sound assessment results.

Key words:lake’s eutrophication assessment,fuzzy assessment method,grey assessment method,weight,correlation,set pair analysis
