Ecological bag based ecological three-section treatment method for river-lake side slope

Abstract

The invention relates to an ecological bag based ecological three-section treatment method for river-lake side slopes, which comprises the following steps: dividing into three slope sections, namely an underwater protection slope, a water-level-fluctuating zone protection slope and a revetment protection slope; carrying out ecological restoration of an underwater protection slope section, a water-level-fluctuating zone protection slope section and a revetment protection slope section aiming at different slope sections; paving ecological bags in a step-shaped laminated stagger way; and planting plants on the ecological bags. The ecological three-section treatment method disclosed by the invention can be used for treating the water conservancy side slope in sections by separating the water conservancy side slope into three slope sections,namely an underwater slope section, a water-level-fluctuating zone slope section and a revetment slope section, ensures the requirement for flood discharge and takes the landscape diversity and ecological diversity as a treatment target on the basis of the structural safety of the river-lake side slopes and also utilizes the cooperative treatment capacity of the river-lake side slopes on water bodies.

Description

technical field [0001] The invention relates to an environmental treatment method, in particular to an ecological three-stage treatment method for river and lake slopes based on an ecological bag, and is a flexible ecological slope engineering system. Background technique [0002] The traditional water conservancy slope protection scheme mainly focuses on the functional requirements of flood discharge and shipping. For the revetment and slope protection works of rivers and lakes, the safety and durability of the engineering structure are mainly considered. Therefore, the governance model mostly adopts linear rivers and river channels. However, hardened materials such as masonry, concrete or reinforced concrete are used, and the ecological function of the river is rarely considered. [0003] The above-mentioned channelized and hardened water conservancy slope blocks the communication between river water and groundwater, and at the same time causes the soil behind the hardened...

AI Technical Summary

Problems solved by technology

[0003] The above channelized and hardened water conservancy slopes block the communication between river water and groundwater, and at the same time cause the soil behind the hardened slope to become alkaline, become dead soil, lose nutrients, lose the growth environment for shore plants, and lose the growth and reproduction environment of microbial communities , aquatic animals disappear or even become extinct due to the loss of the ecological chain, the underwater biological community disappears, and the self-purification ability of the river channel disappears. Coupled with the joint action of rural domestic sewage and urban sewage, rivers and lakes enter a vicious cycle of black and foul odor
