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
- Hydro total potential: 0.4-0.5billion kw/hrs • - Current: 0.14 – 0.2 billion kw/hrs • 12th 5 yr plan: 2/3 of 11.4% non-petro based energy
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
