Evaluation of water quality in mangrove ecosystem for the Beilun Gulf and Zhenzhu Bay: A Complex Approach

Abstract

Water quality evaluation is vital for water monitoring and management in mangrove ecosystem of Beilun gulf and Zhenzhu bay in Guangxi of china. Over the past few years, with the expansion of urbanization and economic development, the coastal water quality in mangrove ecosystem is becoming worse. This literature applied the Fuzzy C-Means (FCM) and principal component analysis (PCA) techniques to evaluate the water quality in the study area and to evaluate the overall rating of stations with respect to the 14 water quality parameters. The PCA analysis is based on the precise clustering of FCM analysis. More reasonable evaluation of water quality by PCA was obtained. Our numerical analysis has verified the result of the current paper is correct. In addition, those results can provide some selectable methods to improve station number for interrelated management department with the limit funds and resources.
