Optimized Approach to Setting up Water Quality Monitoring Crosssections
Optimizing of water environment quality monitoring in Chongqing section (within the Three Gorges Reservoir) of the Yangtze River was explored in order that the monitoring points could be set up in a scientific and reasonable way,and at the same time,the data obtained could better represent the water environmental quality of Chongqing section,the Yangtze River.In this study,the existing data over the past five years at 25 monitoring cross-sections of Chongqing section were collected and analysed.The optimizing process was involving the methods such as correlation analysis of the existing data,fuzzy clustering method and matter-element analysis;thereafter,the F test and t test were used to verify the results,which showed that no significant difference appeared between the two sequences,which suggested the optimization of water environment quality monitoring in Chongqing section could be subsequently achieved.
