中文摘要 | 本文分二部份,第一部份採用因子分析其能將雲林沿海地區地下水質資料進行歸 納、整理和分類,提供邏輯推理方向之特性,以評估雲林沿海地區地下水質污染情形,結果 顯示影響雲林沿海地區地下水水質的主要因子有兩項,分別為出電導度、總溶解固體量、氯 鹽、硫酸鹽、鈉、鉀及鎂共七個變量所組成的「海水鹽化因子」與由總鹼度、總有機碳及砷 三個變量所組成之「砷污染因子」。以此兩項因子所代表所有 13 項地下水水質項目,具有 78% 之代表性。 |
英文摘要 | The study consists of two parts. The first part applies the multivariate factor analysis method to evaluate the groundwater pollution in the coastal area of Yun-Lin. The method provides the general direction of summarizing, trimming and classifying the original data. The results show that the seawater salinization factor including EC, TDS, Cl-, SO ����, Na ��, K ��, and Mg ��, and the arsenic pollutant factor including Alk, TOC, and As, are two major influential factors on the groundwater quality in the coastal area of Yun-Lin. The seawater salinization and arsenic pollutant factors represent 78% of the total 13 groundwater quality analysis items in Yun-Lin. |
