人工濕地是利用自然生態系統中水生植物對污染物的吸附或分解的原理達到水質淨化的效果,但人工濕地的環境和目的各有不同,所以規劃模式上各異。水生植物是人工濕地中重要的淨化元素之一,每種不同的水生植物因生理構造不同所產生淨化效果和吸附物質也不同且其適合的環境亦不同。整體的配置上,如何選用合宜的水生植物以建構出自然的生態系統達成淨化水質目的,成為人工濕地的重要課題之ㄧ。 本研究統整分析水生植物不同種類的特性,並依人工濕地系統的環境因素、人工濕地的種類、表面流人工濕地系統(free water surface flow system, FWS)、地下流人工濕地系統(subsurface flow system, SSF)、環境因素(水生植物生長的分佈地區、水生植物生長的海拔高度、水生植物的繁殖方式、水生植物生長的氣候);水生植物(外觀特徵、抗污能力、去污種類、植物特性、生態機能)等因素,作為水生植物的選用查尋因子,提供規劃人工濕地時選用水生植物的快速查詢及設計參考依據。
Artificial wetland uses characteristic of the aquatic plant to absorb and resolve pollution. Nevertheless, the goal and environment of artificial wetland are different from each other. Therefore the constructed model is based on its need. The aquatic plant is one of the most important key facts to clean the pollutant. Every different aquatic plant has its own growing environment and different capability to absorb particular pollutant. How to choose the right aquatic plant and reach the setting goal is not an easy task. This research attempts to search all the available aquatic plants in Taiwan. By analyzing the characteristics of different aquatic plant, the results are listed in the Excel file. The user can easily to check all information, such as the climate, the water level and pollutants about each aquatic plant. By trading off all facts one considered, it become easier to decide the right aquatic plant.
