岷江彭山江口—乐山段梯级开发优化方案

Optimization scheme of cascade development from Pengshan Jiangkou to Leshan section of the Minjiang River

针对岷江彭山江口—乐山段原规划梯级方案间距近、电站动能经济指标差、开发难度大的问题,以全面实现岷江航道达标升级为目标,结合规划建设条件的变化情况,全面分析优化方案在通航、发电效益、环境影响等方面存在的问题和效果,得出了将岷江彭山江口—乐山段梯级开发由8级优化为6级的优化方案。优化方案为《岷江成都至乐山段航运发展规划》编制提供技术支撑,显著提升了航运效益、发电效益和水环境效益,极大提高了开发方案的可实施性,为岷江高等级航道的建设奠定了坚实的理论基础和规划指引。

The original planning cascade scheme of the Pengshan Jiangkou to Leshan section of the Minjiang River is close, the kinetic energy economic index of the power station is poor, and the development is difficult. Regarding these problems, with the goal of fully realizing the upgrading of the Minjiang River waterway, combined with the changes in the planning and construction conditions, the problems and effects of the optimization plan in terms of navigation, power generation efficiency and environmental impact are comprehensively analyzed, and the optimization scheme for the cascade development from the Pengshan Jiangkou to Leshan section of the Minjiang River is optimized from 8 to 6 levels. The optimization scheme provides technical support for the preparation of the shipping development plan for Chengdu to Leshan section of the Minjiang River,significantly improves the shipping efficiency, power generation efficiency and water environment benefit, greatly improves the feasibility of the development scheme, and lays a solid theoretical foundation and planning guidance for the construction of the Minjiang River high-grade waterway.
