Slope vegetation protection method for water body swelling and subsiding zone

Abstract

A kind of vegetation slope-protection at the water disappearing-rising strap, relates to the harness methods of water's bank erosion. The invention adopts the flood- proofing, barren-proofing, drought-defying plants, which is fit to grow at the water disappearing-rising area, to be the slope-protection vegetation; builds the barrette grass vegetation at the water disappearing-rising strap by multiplying the barrette grass seedling, preparing the radical caudexes barefooted seeding of the barrette grass which is fit to grow at the water disappearing-rising strap, planting it in high density at the certain bank slope. It adopts the radical caudexes barefooted seeding for it is low in cost, strong in bourgeon ability, swift in growth and able to become vegetation rapidly. The invention has the characteristics of afforesting the water disappearing-rising strap, rust-preventing, protecting and purifying water.

Description

technical field

[0001] The invention relates to a control method for bank slope erosion of a water body. Background technique

[0002] The water body depletion zone refers to the shore zone between the low water level and the normal high water level of a water body (reservoir, river, lake or pond). Due to the alternation of water level rise and fall, the environment changes greatly in the sub-expansion zone, and it is difficult for ordinary plants to adapt to it, and they are often exposed. Under the action of water level fluctuation and wave erosion, the erosion of the sub-expansion zone is more typical. In many large and medium-sized reservoirs, bank collapse often occurs, and the erosion of the ups and downs causes silted water bodies and damages water conservancy facilities. If engineering measures are adopted for its governance, not only the cost is high, but also the original natural slope is destroyed, so the gain outweighs the gain. However, the use of vegetation s...
