Scope

Scope: This document is applicable to guiding the ecological restoration work of the recession zone of the Three Gorges Reservoir. The ecological restoration of other reservoir recession zones can be used as a reference. Main technical content: 1. For recession zones with special natural geographical conditions where any form of disturbance is not appropriate, and where the natural ecological environment conditions are still good, adopt protection and management measures to reduce and avoid human activities. The main methods include natural restoration and natural development to protect the structure and function of the ecosystem. 2. For areas suitable for natural restoration models, artificial restoration techniques can be used. The main techniques include: (1) Vegetation community construction. Generally, in the upper section, trees are the main species for community construction, forming a complex community of trees, shrubs, and grasses; in the middle section, tall grasses and shrubs are the main species, forming a mixed community of tall grasses and shrubs; in the lower section, perennial herbaceous plants are the main species, forming a low-lying herbaceous plant community. In addition, in the areas with large amounts of water accumulation after water recession in the middle and upper sections, ecological restoration can be carried out by constructing artificial wetlands. (2) Engineering techniques. For recession zones with poor foundation substrates and high human interference, such as docks and sand pits, engineering techniques are used to promote the construction of plant communities. On the basis of improving the habitat quality of the slope and bank of the recession zone by ecological slope protection techniques such as anti-scour ecological slope protection components, beaded flexible shore protection techniques, ecological bag slope protection techniques, and composite anchor pad ecological slope protection techniques, herbaceous and shrub plants are
