Technical guidelines for river-lake ecosystem conservation and restoration engineering.

These Technical Guidelines are developed to guide the protection and restoration of river-lake ecosystems.
The main contents of the Technical Guidelines include river and Lake ecosystem investigation and evaluation, design principles, water quality protection and improvement, river and lake landform protection and restoration, biodiversity protection of important aquatic habitats, water culture inheritance and water landscape construction, materials, monitoring and management, etc.
The Technical Guidelines are applicable to the design of ecosystem protection and restoration engineering for large and medium rivers, important lakes and other waters. For the design of ecosystem protection and restoration engineering for small rivers and other lakes they may be applied by reference. They are also applicable to the design of ecosystem protection and restoration for water conservancy and hydropower engneering projects, as well as ecological transformation, ecological dispatching and management.
