Basic Principles of Ecological River Regulation
1. Comprehensive Principle: On the premise of guaranteeing the basic functions of flood control, waterlogging drainage and water diversion, river ecological control should fully consider the needs of river ecological functions, water purification, ecological landscape and other functions, while taking into account the safety of hydrophilic activities.
2. Coordination principle: embodying the characteristics of river course and surrounding area development, focusing on the coordination with the overall style along the line, and the coordination between river ecological landscape and surrounding landscape.
3. Principles of naturalness: Rehabilitation of natural aquatic ecosystem habitats in rivers should be adhered to, with natural restoration as the main method and artificial restoration as the supplement, taking measures according to local conditions and making full use of the morphological, topographic and hydrological conditions of the existing rivers; selection and allocation of species should be based on native species, so as to construct a strong self-sustaining and stable aquatic ecosystem. Unification.
Fourth, the principle of economy: synchronizing with economic and social development, adjusting measures to local conditions, saving energy and efficiency; coordinating early construction and late maintenance, reducing construction costs and maintenance costs as much as possible, so as to achieve sustainable development of river ecological governance.
