Major threats to Fresh Water Fish
水利变化 Changes to hydrology– 水坝、跨流域调水、抽取地下水 水污染 Water pollution– 城市、工业点源、农业非点源 外来入侵物种 Invasive Species 栖息地破坏 habitat damage– 渠化、航道建设过度捕捞 overharvesting全球气候变化 climate change

Hydrodam and low-carbon society低碳社会中的水电水电的诱惑 hydropower’s temptation:
– 清洁的 , 可再生的能源;没有或者几乎可以忽略不计的二氧化碳排放量 clean and neglectable CO2 emission particularly in post-Copenhagen era
– 就当前的能源状况而言,水电是一个不可能回避的选择 hydropower Vs coal-based energy production;“ 清洁”水电的生态影响 : Ecological impact of
“clean" hydropower– 改变水文过程– 改变水温和泥沙量– 淹没栖息地– 洄游通道被阻断– 洪泛平原丧失
