Amphibious floating island suitable for riparian zone and construction method of revetment of floating island

Abstract

The invention discloses an amphibious floating island suitable for a riparian zone. The amphibious floating island comprises floating bed units and fixing devices, wherein the fixing devices are fixedly arranged along the embankment direction, a plurality of floating bed units are longitudinally and horizontally arranged along the bank, and adjacent floating bed units are in flexible connection with each other through a rope lock. The invention also discloses a construction method of a revetment applying the amphibious floating island. The construction method mainly comprises the steps of fixing the floating island at the highest water line in the riparian zone of a reservoir, and arranging emergent aquatic plants which accord with the regional characteristics of the Three Gorges reservoir region on the floating island. The floating island is simple in structure and flexible in application, and can produce a corresponding 'bending' phenomenon in the process of matching with the increase amount of water level. The emergent aquatic plants on the floating island can satisfy the requirement on improvement of the ecological environment of a water body, and afforest the bare riparian zone when the water level falls without secondary pollution, so that the amphibious floating island has an eco-friendly effect, and is especially suitable for littoral zones with great water level fluctuation.

Description

technical field [0001] The invention belongs to the fields of water conservancy, environment and ecological restoration, and in particular relates to an amphibious floating island suitable for a water-fluctuating area and a bank revetment construction method thereof. Background technique [0002] Water-fluctuation zone refers to the alternating wet and dry zone formed by seasonal fluctuations of water bodies such as reservoirs, rivers, and lakes, and the periodic inundation of land at the junction of water and land; as a buffer zone between water bodies and land shores, it has the ability to intercept agricultural non-point source pollution on the banks of reservoirs. , water body protection, maintaining ecological environment diversity and landscape aesthetic functions. [0003] At present, the largest drawdown area in my country is the drawdown area of ​​the Three Gorges Reservoir. The Three Gorges Reservoir operates in accordance with the water level operation mode of low...

AI Technical Summary

Problems solved by technology

However, the existing floating islands are all aimed at water bodies such as ordinary rivers, rivers, and lakes, and the floating islands that can be applied to the special water-land alternating environment of the sinking zone are still in their infancy; Restoration of ecosystem revetment is still in a blank stage
