摘要:

针对三峡工程建设过程中可能引发的生态与环境问题,基于三峡工程建设前后库区生态环境变化,对17年工程建设过程中,库区及上游开展的各项生态环境保护措施及其效果进行总结评价。结果表明三峡库区各项生态环境保护措施有力得当,移民及工矿搬迁环境压力降低,干流水质基本稳定,地质灾害防控得当,库区及上游生态恢复加速,库底清理清漂彻底,媒介生物密度下降,人居环境逐步改善,库区生态环境质量总体趋好。鉴于库区“限制开发区域”的国家主体功能区定位、生态环境的复杂性及相关影响因素的滞后性,生态环境保护工作仍需要进一步加强,特从管理、技术与经济三方面对三峡水库运行管理期内的库区生态环境保护工作提出建议,旨在为相关管理部门提供决策参考依据

Abstract:

The construction of Three Gorges Project may lead to ecological and environmental problems.Based on ecological environment change in the 17years construction process,this paper assessed the ecoenvironmental protection measures and effect in construction term of Three Gorges Project.The results showed that the ecoenvironmental protection measures on Three Gorges Reservoir were appropriate and effective,environment pressures on migration and enterprise relocation were reduced,water quality kept stable,geological disasters were proper prevented and on control,ecological restoration in the reservoir and upstream area speeded up,drifts in reservoir bottom were cleared completely,vector density decreased,human settlement improved,overall,ecological environment quality of the reservoir area were sound.In view of the location of “limited development” functional areas,the complexity of ecological environment and the lag of relevant factors in the area,the ecological environmental protection work needed to be further strengthened.The paper made suggestions for the ecoenvironmental protection in the next operation and management period from three aspects of management,technical and economic,to make recommendations for the relevant administrative departments
