| Abstract: | Based on the analyses of water quality monitoring data of over 120 hydrometric stations in the Yangtze River System during the last 30 years,the effect of lithology and climate (rainfall) on major ion chemistry of the river water has been studied by means of statistical approaches such as principal component analysis (PCA) and correlation analysis. |
