中文摘要 | 本研究針對龍鑾潭水澤水質作一監測,並以多變量統計方法分析水質環境之潛在因子及周遭農事活動對水質的影響。研究結果顯示:影響本水系環境主要之潛在因子包括「營養鹽」、「懸浮固體」、「溫度」和「鹽害」等。以水質理化性質作採樣點分區並對照現地農業活動情事,發現採樣點可分區分為三個分區,而這三個區域水質特性主要係受到灌排農事活動及社區民眾生活所產生、受牛羊畜牧活動所產生、受到民眾釣魚及摸蛤貝活動所產生及一般湖泊及魚塭活動所影響之水質特性。雖然本灌區主要係以農業之有機性污染為主,然本研究可說明不同之農事活動所呈現之水質特性亦有差異。 |
英文摘要 | Multivariate analysis was used to assess the water quality characteristics of Lung-Luan-Tarn swamp, the latent factors, and the affect by people activities. From factor analysis the results showed that the most important latent factors among these area are eutrophication, suspended solid, temperature, and salinity etc. Cluster analysis was performed with factor scores computed from those latent factors. Then we classified the Lung-Luan-Tarn watershed into three distinct regimes using sampling stations, it showed that irrigation water quality was influenced by agricultural activities including farm activities, domestic activities, livestock breeding activities, fishing, pick-up oyster activities, and fish farming activities. In conclusion, the use of factor and cluster analysis enabled the classification of these samples, and to determine the extent of pollution in agricultural fields remote from different kinds of agricultural activities. This method enabled the determination of the probable sources of pollution to some agricultural fields. |
