5、arn more through the standard articleAbstract The plateau lakes （高原湖泊）of Yunnan are important both ecologically and economically in China. Nevertheless, the human impact on water quality in these lakes has become increasingly highlighted. The water quality of 10 plateau lakes was monitored regularly

6、 over the period of 2000 through 2004 for 24 parameters(因素，特征). Multivariate statistical techniques, including cluster analysis (CA), factor analysis (FA), and principal component analysis (PCA), were employed to better interpret information about the water quality and its pollution sources. continu

9、TRODUCTION MATERIALS AND METHODS RESULTS AND DISCUSSION CONCLUSIONS INTRODUCTION Yunnan lakes, described as the pearls on the plateau, play a crucial role in water supply, fishing, waste disposal, lake reclamation, agriculture, and industry However, the catchment area of these lakes has been subject

For example, several water-q

These programs raise a novel issue, that is, how people should make good use of a huge and complex data set containing a large number of physicochemical parameters.

13、n Province have been examined by unsupervised pattern recognition (hierarchical cluster analysis) and display methods (PCA) to obtain correlations between variables and water quality similarity in groups of lakes. Cluster analysis confirmed the existence of three types of water quality (i.e., low-,

14、medium-, and high-polluted lakes). Although three PCs needed 14 variables to explain 85.01% of the original data set, which indicated that no obvious data reduction was obtained, three latent factors can identify different pollution sources: agricultural and industrial activities, residential activi

Box-whiskers plots of water quality variables showed visually the spatiotemporal variations of water quality variables, which may help further analyze the pollution sources loading into these lakes.
