水利水电工程对生态环境的影响及保护对策

Impacts on the Eco-Environment of the Hydraulic and Hydropower Projects and Protection Countermeasures

水利水电工程建设在除害兴利、产生丰富可再生绿色资源的同时,也不同程度地破坏了原有生态环境的平衡。水利水电工程可以有效拦蓄洪水,提高河道过流能力,改善下游生态环境等,但同时对河流生态和社会环境产生不利影响。在水利水电工程建设过程中,应增强生态环境保护意识,进一步健全水利水电工程环境影响评价体系,建立和实施生态补偿机制等,保护生态环境。

With the benefit promotion and damage reduction, abundant renewable green resources production, water and hydropower engineering works also destroy the original ecology balances in some degree. Water and hydropower engineering works can intercept flood, improve channel flow capacity and downstream ecotype, at the same time there will be some negative impacts on fiver ecosystem and social circumstances. So some meas- ures should be done to improve the environmental awareness, perfect the environmental impact assessment system and establish ecalogical compensation mechanism in the process of water and hydropower engineering construction.
