关于大坝对流域生态系统的影响及对漓江水资源管理的思考

The Effect of Dam on River Ecossystems and Management of Lijiang River

江河溪流是陆地生命的血脉,理应受到人类的珍爱。完善的流域生态系统的维持依赖于其自然动态特征的保持。人工堤坝改变了水流的自然模式,引起流域生态系统的强烈反应。人们对河流生态的恢复和管理,应模仿河流的自然动态模式。漓江是桂林旅游的“黄金水道”,对漓江水资源的管理和漓江的生态保护也应遵循其自然规律,对该流域的开发利用,要控制在其环境容量范围内,走可持续发展之路。

Rivers and streams are the blood and vein of lives on the earth. They ought to be cherished by the people. The ecological integrity of river ecosystems depends on their natural dynamic character. Artificial dams alter the nature flow regimes and ecological responses to altered flow regimes. Managing and restoring rivers should mimic a natural flow regime. The paper also puts forward that the harness of the Lijiang River must be combined with researching sustainable development countermeasures, conforming to the nature rules, considering its capacity.
