Abstract

The relationship model between chlorophyll-a in water body and sediment nutrients in Xiangxi Bay of Three-Gorge Reservoir was established using support vector machine (SVM) method. In surveys, six stations have been investigated on 29 March 2009, 28 March 2010 and 17 August 2010. Using stepwise multiple linear regression method, the important variables (sediment total nitrogen and bioavailable phosphorus) were selected. The parameters in SVM were optimized by leave one out cross validation. The cross validated squared correlation coefficient obtained based on leave one out method (\( Q_{LOO}^{2} \)) of the optimal SVM model is 0.7577. The SVM method has been shown to be a useful and powerful tool to construct the relationship model.
