碩士 / 大仁科技大學 / 環境管理研究所 / 99 / Canonical correlation analysis (CCA) method in multivariate statistics was applied to interpret the interrelationship between water quality parameters and algal indexes in Lin-Lo artificial wetland. Two items were included in this study. The first is to discuss the interrelationship between water quality parameters and algal indexes like QI and ATSI. The second is to discuss the interrelationship between water quality parameters and algal indexes such as McI and ATSI. For the relationships between water quality and algal indexes of both QI and ATSI, two sets of constructed canonical variables, the water quality parameters could account for 86.40 % for the total variance of biomarker of algae. High explanation was attributed to the first sets of canonical variables with 0.94 of correlation coefficient .The first sets of canonical variables reveals that algal index of QI are dominantly controlled by the facotrs of DO, pH, TN and TP. However, the second sets of canonical variables including DO, pH and TP could affect algal index of ATSI.
For the relationship between water quality and algal indexes of both McI and ATSI, two sets of constructed canonical variables, the water quality parameters could account for 86.66 % for the total variance of algal indexes. High explanation was mostly results from the first sets of canonical variables having 0.94 of correlation coefficient. The first sets of canonical variables, like DO, pH, TN and TP, were the main factors controlling algal index of McI. The second sets of canonical variables consiting of pH and TP could effectively control the algal index of ATSI. Based on the relationships between water quality and algal indexes using methodologies, it provides a helpful information concerning ecological conservation and wetland management.
