Abstract: Environmental and ecological data in Nan-Shih stream were investigated in this study to comprehend the ecological demands. Based on the data collected, the IBI index (Index of Biotic Integrity) which takes fish species as the major target, the FBI aquatic insects Hilsenhoff index (Family-level Biotic Index) and the GI (Genus Index) index of algae were thus analyzed to quantify Nan-Shih stream’s ecological system. The indices above were then applied on ISC index (Index of Stream Condition) to describe the overall river condition, including the hydrology, physical form, streamside zone, water quality, and aquatic life. The priority of the river corridor restoration or the habitat improvement was thus proposed for government as a reference for river management.
