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

Embodiment 1

[0045] refer to Figure 1-3 As shown, the present invention provides a restoration method for urban river ecology. This project case was implemented in October 2019, and it is aimed at the restoration of river ecology in a river section in Jiangning District, Nanjing City. The length of the section is about 6km , the width of the channel is 20-25m, and the deepest part of the channel is about 4.5-6m. The entire river course mainly receives rainwater from urban areas along the river and domestic sewage from residents. The ecological restoration of urban rivers this time mainly includes the overall comprehensive reconstruction of the river, the reconstruction of the deep water, shallow water and floodplain area of ​​the river, the reconstruction of the revetment belt and the reconstruction of the river slope. The comprehensive transformation of the whole river course includes the transformation of the planar and cross-sectional structure of the river course, and the control and...

Embodiment 2

[0053] refer to Figure 1-3 As shown, the present invention provides a restoration method for urban river ecology, specifically: this project case was implemented in May 2020, and is aimed at the restoration of river ecology in Yaohai District, Hefei City, with a section length of about 15km , the width of the channel is 30-35m, and the deepest part of the channel is about 3.5-5.5m. The entire river course mainly receives rainwater from urban areas along the river and domestic sewage from residents. The ecological restoration of the urban river mainly includes the overall comprehensive reconstruction of the river, the reconstruction of the deep water, shallow water and floodplain area of ​​the river, the reconstruction of the revetment and the reconstruction of the river slope. The comprehensive transformation of the whole river course includes the transformation of the planar and cross-sectional structure of the river course, and the control and regulation of the hydrology o...

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...
