中文摘要 | 大鵬灣水域環境影響因子暨初級生產力評量因子透過典型相關分析,可知本水域環境影響因子:水溫、鹼度、氯鹽、電導度、總氮、總磷、UV-254、氫離子濃度指數、總菌落數、溶氧等10個變項,與評量初級生產力最常用之藻數及葉綠素-a兩目標函數變項間有相關性存在。在兩組典型變項因素裏水域環境影響因子對初級生產力評量因子的解釋變異量為39.25%;其中絕大部份的解釋能力來自於第一組典型變量因素,相關係數為ρ=0.84。而第二組典型變量因素的解釋能力除較低外尚不顯著。第一組典型變量因素顯示初級生產力評量因子葉綠素-a受到水域環境影響因子的影響主要是總菌落數、鹼度、水溫、總氮及氫離子濃度指數等。第二個典型變項因素顯示初級生產力評量因子藻數受水域環境影響因子的影響主要是總磷、UV-254、電導度、總氮、氫離子濃度指數、水溫、鹼度及總菌落數等最深遠。透過此多變量分析方法可找出水域環境影響因子與水域初級生產力評量因子間的關係,期望此些方法及結果對資源保育及環境管理上能提供很大的助益。 |
英文摘要 | This work we use canonical correlation analysis to interpret the interrelationship between factors of water quality parameters (T, AlK, Cl, EC, TN, TP, UV-254, pH, HPC, DO) and primary production parameters (Algae, Chlorophyl-a). In these two sets of constructed canonical variables, the water quality parameters could account for 39.25% for the total variance of primary production but almost results from the first sets of canonical variables and its correlation coefficient reaches to 0.84. The main factors that controlling chlorophyll-a are HPC, AlK, T, TN, and pH. And the second sets of canonical variables shows that the main factors that controlling algae count number are TP, UV-254, EC, TN, pH, T, AlK and HPC. These methodologies and results enable to understand the interrelationship between factors of water quality and primary production and can provide useful information concerning resources conservation and environment management. |
