Principal Component Analysis is used to reveal the mutual relationships of various factors. It is shown that there exists an obvious special and temporal variation in the main factors of water quality. Annual values of TP, TN, and Chl.a fluctuate seasonally. In addition, Chl.a has a synchronous variation with water temperature, although being lagged a little, and closely relates to TP and TN. SD has a good negative relation with Chl.a. The results from Principal Component Analysis show that SD, Ec, Tw, pH and Chl.a are the most influential factors in water quality of the West Lake., Article, 信州大学理学部附属諏訪臨湖実験所報告 11: 21-27(1999)}, pages = {21--27}, title = {DYNAMIC VARIATION OF WATER QUALITY IN WEST LAKE AND MULTIVARIATE ANALYSIS OF ITS PRIMARY FACTORS}, volume = {11}, year = {1999} }
