| 内容記述 | The water qualities of TENRYU River in NAGANO Prefecture were intended to explain by using statistical techniques. Correlation analysis and Principal components analysis were employed for this study. In correlation analysis, observed stations were divided into two parts. One is the stations where SS is correlated with organic matters and the other is not. Even in the most part of the former, the correlation coefficients between SS and BOD are different from those between SS and COD. This result indicates that composi-tion of SS is not same in each station. In principal components analysis, the communality of the first 3 principle components is about 75% of the total variance of the original data. An interpretation of each principle component is as follows: First principle component: Index of pollution by organic matters. Second principle component: Stability index of natural environment or intensity of social (human) effects. Third principle component: To our regret, this component could not be interpreted in this study. Using Factor loading, 10 observed stations were classified into 5 groups by their water qualities. And it suggests that this procedure may be useful for water qualities investigations. | |||||
