摘要

近年來根據釵h研究顯示，濕地除了具有生態多樣性之外，還具有蓄洪以及淨化水質之弁遄A水質良莠影響人類生活甚鉅，因此了解濕地的淨水能力是值得研究之環境課題。本研究以台灣北部地區淡水河之二重疏洪道濕地為例，建立一維與二維之濕地泥沙/水質模擬之架構，使用WASP水質模式與SMS水理模式，配合二重疏洪道濕地的地理條件與現場採樣資料進行水理與水質模擬，共模擬了二重疏洪道濕地的泥沙與重金屬之傳輸現象，得到初步的分析結果。此分析架構可作為濕地水質淨水能力之評估方法，以及往後水質模擬與模式應用之參考。

According to recent studies, wetlands not only have high biodiversity but also have the capability purifying water. Water quality is so important to human life. Therefore, understanding wetlands’ ability of purifying water is an worthy environmental issue to study.
This study took Erh-Chung Flood Way for example, to build up a frame of wetland sediment transportation modeling and water quality modeling. Using WASP and SMS models combined with geographic data and field sampling data to simulate hydraulic and water quality phenomenon in the Erh-Chung Flood Way. This study discussed the features of sediment transportation and heavy metal transportation in wetlands. After analysis, this study obtained some useful information form simulation results.
This frame of the analysis can be used as a tool to estimate the purify ability of wetlands. Also, it can be a reference for water quality modeling and for model application.
