本研究以棲流棲地量化評估為重點，採4種方法探討棲地品質的變化，以花蓮縣荖溪中游整治工程河段區域為研究場址，進行魚類調查、無人機空拍河段並解算數值地表地形及綠覆率分析，並以二維水理模式CCHE-2D計算模擬範圍流速水深，流量採1.0 cms與514 cms（Q50），以模擬的各網格流速水深，判釋各水域型態多樣性指數變化，再以臺灣白甲魚及大吻鰕虎之適合度曲線資料，計算魚類棲地適合度、權重可用棲地面積，並以福祿數評估魚類的適合區域面積占比。

This paper focuses on the methodology used in quantitative stream habitat assessment. For the Lao stream, we investigated presence of fish and UAV photographs and calculated green coverage by using the Visible Atmospherically Resistant Index (VARI). The National Center for Computation Hydro-Science and Engineering 2D (CCHE-2D) model was used to simulate the velocity and depth of water in the river segment. The discharges were 1.0 and 514 cubic meters per second (m^3/s). We used the simulated velocity and water depth values of each element to identify the aquatic habitat type and calculate Shannon's diversity index. Based on the habitat suitability curve for Onychostoma alticorpus and Rhinogobius gigas, we calculated the habitat suitability indices and Weighted Usable Areas (WUA) for different sites along with discharges. The Froude numbers were simulated by the CCHE-2D model, which we used to identify suitable areas of the river segment for fish habitats.
