灰色關聯理論應用新海橋人工濕地多指標水質分析

Application of grey relational theory on multi-index water quality analysis for Xinhai Bridge constructed wetlands

指導教授 : 陳鈞華

摘要


目前國內人工濕地在水質數據觀測不易,因此難以有效的使用統計進行相似度分析。灰色關聯性分析具有在有限水質數據進行灰系統參數間相似度分析的能力,本研究分別針對2009、2010年台北市新海橋人工濕地水質參數氫離子濃度pH、溫度Temp、導電度EC、懸浮固體SS、生化需氧量BOD,以灰色關聯性和加權權重進行分析比較。結果顯示:溫度對pH相似度為0.92;pH對溫度相似度為0.92;Temp、BOD對EC相似度為0.77;BOD對SS相似度為0.68;EC、SS對BOD相似度為0.685。本研究結果可提供未來規劃新海橋人工濕地改善水質之最佳參考依據。

The constructed wetlands were not general that made the data of water quality observe unchangeably, it is difficult to use statistical analysis. Limited data of water quality can be analyzed by grey relations, and be compared with similarity of parameters in grey system grey relational theory. In this paper, using grey relations and weighting to analysis the parameters of constructed which are concentration of Hydrogen ion concentration pH, Temperature Temp, Conductivity EC, Suspended solids SS and Biochemical oxygen demand BOD in Taipei city Xinhai, each for 2009 year and 2010 year. The result shows that SS to pH is the most influential, pH to Temperature is the most influential, pH to BOD to EC is the most influential, Temperature to SS is the most influential and SS to BOD is the most influential. In this study, the result can provide for planning the constructed wetlands of Xinhai to improve water quality.
