【Abstract】 The author made a summary on influencing factors of dams on fish habitat, referring to flow condition, water temperature,water quality, reservoir substrate and morphology. The author also reviewed the main methods of forecast and assessment for habitat changing due to dam construction at home and abroad and analyzed the characteristics of these methods.
