River ecological management method and system

Abstract

The invention relates to a riverway ecological management method and system, and relates to the field of riverway ecological restoration. Comprising the steps that firstly, at least two gabion gabion nets in a river channel are transversely arranged in the river channel in the flow direction of the river at intervals, a backflow pond is formed in the upstream of the gabion gabion nets in the river channel, and aquatic vegetation is planted in the backflow pond; 2, presetting a flood water level, a design water level and a normal water level; step 3, planting flood-resistant herbaceous plants and / or shrubs on the river channel or the side slope between the normal water level and the designed water level; arbor is planted on a river channel or a side slope between the designed water level and the flood water level. The method has the beneficial effects that the river channel not only can ensure proper flowing of the river, but also cannot cause siltation caused by flood scouring, and can meet the standard that the flood is encountered every ten years; the measure that trees and shrubs are matched with plants is adopted, the original monotonous concrete gray of the revetment is covered, the diversity of the ecological landscape of the river channel is achieved, and the comprehensive ecological benefits are improved.

Description

technical field [0001] The invention relates to the field of river ecological restoration, in particular to a method and system for river ecological management. Background technique [0002] The "Overall Plan for the Reform of Ecological Civilization System" clearly puts forward the concept of "establishing the concept that mountains, rivers, forests, fields, lakes and grasslands are a community of life, and comprehensively considering all elements of the natural ecology to carry out overall protection, systematic restoration, and comprehensive management, to enhance the circulation capacity of the ecosystem, and to maintain ecological balance." Require. Put the construction of ecological civilization in a prominent position, and carry out ecological protection and restoration projects of mountains, rivers, forests, fields, lakes and grasses. Rivers are important carriers of natural resources and ecological environment. Nowadays, rivers are over-exploited, water shortages ...

AI Technical Summary

Problems solved by technology

Gravity erosion in some sections of the main channel in this area is relatively serious, and the collapse area is large. The collapse will block the river channel and affect the discharge of floodwater; Migration, the river ecosystem has been severely damaged

[0004] The traditional river channel engineering design only pays attention to the function of the river itself, mostly for the purpose of river channel water delivery and flood discharge, and often uses hardened materials to support the river bed and slope, which not only makes organisms and microorganisms lose their living environment, but also Destroy the self-purification ability of the river and cause serious negative impact on the river water ecosystem
