Riparian zone structure for ecological restoration of urban river channel and restoration method of riparian zone structure

Abstract

The invention discloses a riparian zone structure for ecological restoration of an urban river channel and a restoration method of the riparian zone structure. According to the riparian zone structure, river channel areas related to the technology comprise a deep water area, a shallow water area, a floodplain area, a revetment and a river channel side slope of the urban river channel, the riverway ecological restoration technology takes riverway habitat restoration as a core and is used as a part of a riverway ecological restoration comprehensive system, and a stable riverway ecological system and a natural landscape are recovered and formed from the four aspects of transformation of a riverway plane and section structure, control and adjustment of riverway hydrology, change of a riverway bottom matrix and introduction of fast-growing organisms, transformation of a revetment and transformation of a riverway slope. Different from a traditional engineering type riverway transformation project, the technology is mainly used for improving the function of a riparian zone serving as a habitat of aquatic, hygrophytic and terrestrial animals and plants of the riverway and restoring the biodiversity of the riverway, the ecological integrity and sustainability of the riverway can be essentially improved, and the function of a natural ecological system of the riverway can be restored.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration of urban rivers, and in particular relates to a riparian zone structure for ecological restoration of urban rivers and a restoration method thereof. Background technique [0002] With the rapid advancement of my country's urbanization process and the rapid increase of urban population, a large amount of domestic sewage is produced. Although the construction of domestic sewage treatment plants has reduced the pollutant load on urban rivers, it still causes many modern urban rivers to lose the natural purification ability and ecosystem functions of natural rivers, especially natural rivers as biological habitats It becomes a kind of "dead river" that only plays the role of drainage. And it has seriously affected the aesthetic feeling that the river should have as a part of the resident's living environment in the city. [0003] At present, most of the concepts of urban river managem...

Problems solved by technology

Moreover, in the process of governance, the "engineering" governance model is generally adopted, and the transitional pursuit of "short, flat, and fast" is adopted. A large number of building materials such as concrete and mortar blocks are used to solidify the revetment, occupying the ecological niche that originally belonged to river organisms. Habitat in the riparian zone has been destroyed, with serious consequences for the ecological restoration of the river
