Problems solved by technology

[0004] The purpose of the present invention is to provide a method for ecological restoration of flood protection and slope protection, which can more effectively solve the problem of slope protection ecological capacity decline caused by construction, restore the ecological function and landscape function of slope protection, and is suitable for the treatment of various types of slope protection. According to the characteristics of different types of slope protection, this ecological restoration method mainly considers different types of slope protection, and selects the ecological restoration process of slope protection according to various combinations to carry out scientific ecological restoration of flood protection slope protection. The method is targeted and the process selection is practical. , and can effectively restore the ecological function of flood protection and slope protection, and restore the biodiversity of its slope protection. For the decline in the ecological function of slope protection caused by flood control projects or river channel reconstruction, this process can be directly used for ecological restoration.

Embodiment 1

[0033] A method for ecological restoration of flood protection and slope protection, comprising the steps of:

[0034] A. Determine and analyze the type of flood protection and slope protection: for flood protection and slope protection under different conditions, it is classified according to four types: natural cliff, vertical retaining wall, concrete oblique slope protection and layered concrete slope protection;

[0035] B. Screening of ecological restoration plants for flood protection and slope protection: According to different flooding cycles and combined with the survey results of plants in the natural decline area of ​​the slope protection area:

[0036] The flooding period is more than 9 months, and the plant colonization adopts two different colonization methods, such as natural style or "pin" shape.

[0037] Since the plants in this section are submerged the deepest and longest by the river during the dry season of the Yangtze River, the habitat conditions are wor...

Abstract

The invention discloses a method for ecological rehabilitation of flood control revetment, which comprises the following steps: A, analysing type of a flood control revetment: analysing the flood control revetment on different conditions; B, selecting plants for ecological rehabilitation of the flood control revetment: according to different water encroachment periods and by combining with plant survey result in natural riparian zone of the revetment area, when the water encroachment period is nine months, selecting herbaceous plants which resist water encroachment; when the water encroachment period is five to nine months, giving priority to arbuscles and herbaceous plants; and when the water encroachment period is one day to five months, selecting arbors, arbuscles and herbaceous plants; C, determining ecological rehabilitation of the flood control revetment according to the type of the revetment and by combining with plant selecting for the rehabilitation and the natural precipice: sheltering the dead wall by afforesting, or protecting the slope by oblique concrete, or protecting the slope by layered concrete; and D, revegetating plants in natural riparian zone of the flood control revetment: carrying out landscape renovation and revegetation to the revetment by different techniques for ecological rehabilitation of flood control revetment. The method for ecological rehabilitation of flood control revetment can solve the problem of decreased ecological capability of a revetment caused by construction more effectively and recover ecology of the revetment, and the method is suitable for treating various kinds of revetments.

Description

technical field [0001] The invention belongs to the technical field of flood control and water pollution control engineering ecology, and specifically relates to a method for ecological restoration of flood protection and slope protection, which can more effectively solve the problem of decline in the ecological capacity of slope protection caused by construction, restore the ecological function and landscape function of slope protection, and is suitable for Treatment of various types of slope protection. technical background [0002] The combination method of ecological restoration of flood protection and slope protection is a technology that can effectively improve the ecological restoration ability of flood protection and slope protection, improve the ability of slope protection to absorb pollutants and increase the biodiversity of slope protection. It has a scientific treatment method for various types of slope protection and can be determined according to the type of slo...
