Revetment structure for ecological wetland

Technical Field

The utility model relates to an afforestation technical field especially relates to a revetment structure for ecological wetland.

Background

The river bank is an important component of the river, is a link for connecting a water area ecological system and a land ecological system, and is a connection part of a river land-water crossing zone and a river bank zone. The changes of the river bank ecosystem play the functions of galleries, filters, natural barriers and the like for the logistics, energy flows and biological flows between the water and land ecosystems. The European countries generally advocate the 'natural bank protection' technology, which utilizes biological materials and the like to construct on the river bank and river channel in Switzerland, and plants trees or arranges stones in the water to provide habitat for the fishes. The concept of 'nearly natural river' in Germany is commonly maintained, and the 'natural revetment' technology is simultaneously applied to revetment, spur dikes and drop engineering. Compared with the foreign countries, the ecological restoration of rivers in China often neglects the restoration of the structure and the function of a river ecosystem and the restoration of a river bank part, and has little attention to the restoration of damaged river bank vegetation and wetland communities.

The traditional revetment is a hard revetment built by stones, bricks or concrete and the like, has large construction amount and high cost, and the integration degree of the embankment and the surrounding ecological environment is not enough, so that the hydrophilicity of river channels and the like is poor, the revetment is not suitable for small-space construction and protection of local dam slopes, and more importantly, the living space and the environment of plants, soil animals and microorganisms are not considered in the traditional concrete river bank engineering design of stone masonry and the like. In other words, the existing revetment structures are not conducive to living.
