Interface ecological regulation and control system and method for riverside hydro-fluctuation belt of three gorges reservoir area

Abstract

The invention belongs to the technical field of ecological regulation and control, and discloses an interface ecological regulation and control system and method for a riverside hydro-fluctuation beltof the three gorges reservoir area. The interface ecological regulation and control system is characterized in that a river bank forest land area, a river bank wild flower meadow area and a river bank bush area are arranged on the outer side of a multifunctional buffer area, and the multifunctional buffer area is provided with shallow water area submerged plants, emergent aquatic plant belts, a water border line emergent aquatic plant belt, a low riparian area hygrophyte meadow belt, a riparian upper open forest meadow belt and a transition highland forest belt. According to the interface ecological regulation and control system and method for the riverside hydro-fluctuation belt of the three gorges reservoir area, system structure regulation and control, biological regulation and controland environmental regulation and control are integrated together to form an integral ecological regulation and control system, so that dynamic balance of the hydro-fluctuation belt is realized; by reasonably adjusting a horizontal interface structure, a vertical interface structure, interface substance composition, an interface ecological process and the like, the ecological service function of the interface is enhanced; and through the multifunctional buffer area, the river bank stabilizing and protecting function, the surface runoff intercepting and purifying function, the biodiversity conservation function, the landscaping function, the leisure and recreation function and the like can be achieved.

Description

technical field [0001] The invention belongs to the technical field of ecological control, and in particular relates to an interface ecological control system of the riverside water-fluctuation zone in the Three Gorges reservoir area. Background technique [0002] At present: there is a most closely related and most active interface (or migration control zone) between the river and the environmental medium in the catchment area of ​​the river basin. The riparian zone refers to the area between the highest water level in the flood season and the lowest water level in the dry season on the river bank. This linear band structure is a water-land ecotone, a community ecotone, and an important link between the land catchment area and the river water body. The ecological interface has important ecological service functions such as interception, filtration, purification, habitat, and biological corridors. In addition to seasonal changes in natural dry and flood levels, the banks of...

Problems solved by technology

[0004] (1) In the water-fluctuating zone with a height difference of 30 meters in the Three Gorges reservoir area, it is generally difficult for plants to survive here

Vegetation restoration in a small number of areas but with a single species and low diversity

[0005] (2) The existing technology only designs planting and ignores terrain design and habitat design, and fails to consider the habitat of wild animals
