Problems solved by technology

The above methods only repair the slope from the perspective of plants or structures, and cannot form a stable composite structure that can simultaneously carry out plant greening on the basis of a stable slope structure. loss and revegetation restoration
[0004]The hard water level slope can effectively prevent the slope from collapsing and maintain the stability of the slope, but it cannot provide the growth space for green plants. It is easy to form a large area of ​​concrete coverage, which affects the appearance; and for the restoration of the water-fluctuation zone by pure plant methods, although it can meet the greening function of the water-fluctuation zone, the slope is not stable enough, and it is easy to cause collapse and landslides

Embodiment 1

[0030] 5) Install bermudagrass concrete lawn: Install bermudagrass concrete lawn in the lattice frame backfilled with planting matrix, and use cement mortar above M10 to joint;

[0031] 6) Maintenance: After installation, the slope of the water-fluctuation zone of the vegetation concrete shall be watered, fertilized, weeded, and pest control and management shall be carried out daily to promote the rapid recovery of the slope landscape; When it falls back, it is necessary to closely observe the regreening situation, water and maintain it in time, and remove the inflorescence in time to promote the vegetative growth of the stem.

[0032] Example 2

[0033] 1) Prefabrication of concrete modules capable of planting bermudagrass: choose diabase aggregate with a particle size of 0.8-1.0cm, cement, inorganic mineral powder, water reducing agent, and water according to the weight ratio of 1600:260:30:3.5:68 and mix It is made by pouring. The raw materials are washed or sieved before ...

[0037] 5) Install bermudagrass concrete lawn: Install bermudagrass concrete lawn in the lattice frame backfilled with planting matrix, and use cement mortar above M10 to joint;

[0038] 6) Maintenance: After installation, the slope of the water-fluctuation zone of the vegetation concrete shall be watered, fertilized, weeded, and pest control and management shall be carried out daily to promote the rapid recovery of the slope landscape; When it falls back, it is necessary to closely observe the regreening situation, water and maintain it in time, and remove the inflorescence in time to promote the vegetative growth of the stem.

[0039] Example 3

[0040] This example is to sow bermudagrass on site in the water-fluctuation zone, which requires a long construction time, and it is necessary to choose an appropriate time to ensure that the restoration project will not be affected by the water level.

Embodiment 3

[0044] 4) Install the concrete module: install the concrete module in the lattice frame backfilled with the planting matrix, and point the joints with cement mortar above M10;

[0045] 5) Plant bermudagrass lawns on concrete modules: when the average temperature is above 18°C, sow bermudagrass seeds on the concrete on the side slope of the water-fluctuation zone. No substrate is required for sowing; cover non-woven fabrics after sowing (reveal after germination) open), watering and maintenance every day, spraying foliar fertilizer once a week (0.1wt% compound fertilizer or urea), 40-50 days after lawn can be formed; about 20 days after germination, sprinkle crushed cake fertilizer before the lawn becomes lawn to promote growth Ping.

[0046] 6) Maintenance: Daily watering, fertilization, weeding, and pest control and management shall be carried out on the slope of the water-fluctuating zone after sowing, so as to promote the rapid restoration of the slope landscape; When it f...

Abstract

The invention relates to an ecological restoration method of a hydro-fluctuation belt. The ecological restoration method comprises the following steps of: firstly prefabricating a concrete module on which Bermuda grass can be planted; planting the Bermuda grass resistant to flooding on the concrete module; flattening and tamping a side slope of the hydro-fluctuation belt, and constructing a reinforced concrete lattice frame; backfilling a planting matrix; and finally constructing and curing concrete blocks of a Bermuda grass lawn so as to form a complete full concrete-covered greened side slope of the hydro-fluctuation belt. The ecological restoration method has the beneficial effects of forming a stable side slope protection structure, preventing the side slope of the hydro-fluctuation belt from being directly washed by water waves, and protecting the soil of the hydro-fluctuation belt against erosion, thus achieving the purpose of conserving water and soil; and meanwhile a complete vegetation-covered landscape is formed, thus improving an ecological environment and achieving a wide application prospect and good environmental, social and economic benefits.

Description

technical field [0001] The invention relates to an ecological restoration method of a water-fluctuation zone, belonging to the technical field of ecological environment protection and management. Background technique [0002] After the completion of large and medium-sized reservoirs, the scheduling mode of storing in winter and releasing in summer is often adopted, thus forming a drawdown zone with a water level drop of ten meters or even tens of meters around the reservoir. Water-fluctuation zone or water-fluctuation zone is a unique phenomenon of reservoirs, which refers to the area where the reservoir area is submerged and exposed to the water surface periodically due to seasonal fluctuations in the water level of the reservoir. Its inundation period can be as long as half a year, usually in winter. Due to the change of summer flood and winter dew in the natural environment, the original plant ecosystem has been greatly damaged. If the water-fluctuation zone is not ha...
