Hydro-fluctuation belt side slope ecological management method based on ecological bag

Abstract

The invention relates to a hydro-fluctuation belt side slope ecological management method based on an ecological bag. The hydro-fluctuation belt side slope ecological management method comprises the following steps of: dividing a hydro-fluctuation belt, namely taking an upper limit of a water level of a drought period as a lower boundary of the hydro-fluctuation belt; taking the highest water level line of a flood period as an upper boundary of the hydro-fluctuation belt as the hydro-fluctuation belt; and carrying out ecological repairing: treating a foundation slope surface; paving the ecological bag from the lower boundary of the hydro-fluctuation belt in a ladder-shaped layer staggered manner; and planting amphibious plants or / and hygrophytes on the ecological bag. The technical effects of the hydro-fluctuation belt side slope ecological management method are obvious, namely plant roots penetrate through the ecological bag to form an organic whole body with a slope body, so that the slope body is relatively firm and water and soil loss can be effectively prevented; and no matter whether the amphibious plants are drowned or naked, the afforesting effect and the ecological effect can be guaranteed.

Description

technical field [0001] The invention relates to an environmental treatment method, in particular to an ecological bag-based ecological treatment method for a water-fluctuation zone slope, and 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 slope to be...

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

[0004] Water conservancy slopes can be naturally divided into three slope sections: underwater, ebb zone and bank revetment. Since the three slope sections under water, ebb zone and bank revetment have different ecological functions, the ecological restoration of the three slope sections must be solved The technical problems are not the same: in the initial stage after the formation of the water-fluctuation zone, the terrestrial ecological environment, terrestrial ecosystem, especially the plant community before inundation have undergone tremendous changes, plants are drowned, and the slope consolidation effect of plant roots Disappeared, bringing security risks
