摘要

本研究發展一套魚類環境矩陣法，以具有容易觀察、體型及棲息地敏感度適中等優點之魚類為對象，結合相關環境因子的魚類個體生態矩陣，提供了一個明確的評估方法。本研究進一步將魚類個體生態矩陣中之河川型態、流速、底質粒徑、棲地型態及水質等5大項目定量化，發展魚類環境矩陣方法，以量化研析河川棲地環境品質。並以新店溪為例進行分析，結果發現與實際趨勢吻合，由此可知本方法已能成功地量化分析河川棲地環境在時間及空間上之變化趨勢，適合作為河川復育規劃時參考運用。

Over the last few decades there has been increasing concern for the human impacts on river ecosystems. River managers are increasingly turning from hard engineering solutions to ecologically based restoration activities in order to improve degraded waterways. Although the concepts have been widely accepted by engineers in Taiwan, lack of engineer-friendly appraisal methods hindered further progress of river ecological engineering projects. In this study, we developed 'Environmental Matrix of Fish' as a quantitative tool to evaluate the change of aquatic habitat. Hsin-Dian Stream system was selected as the case study for verification. The results showed that this proposed matrix successfully captured the spatial and temporal change of the fish assemblage, and provided a better understanding of historical influences on fish community structure over watershed scale. The tool with its quantitative environmental factors can thus help engineers identify habitat requirements for the fish communities easily as well as support managing and improving river environment for future restoration applications in Taiwan.
