Example Embodiment

[0015] Example 1

[0016] Such as figure 1 As shown, in the quasi-ecological lake bank slope constructed by the present invention, the embankment adopts a combination of embankment and road, the embankment body is a homogeneous earth dam, and the construction of the bank protection is located above the pavement of the river bed. The trenches excavated on the slope are grid-like, with a width of 30cm-40cm and a depth of 25cm-30cm. For sandy soil slopes, the area within the frame formed by the ditches is 3m 2 ~4m 2 , For the slope of clay soil, the area can be appropriately increased to 5m 2 ~6m 2 . Such as image 3 As shown, high-density root systems are used to plant wet plants such as willow and tamarisk in each ditch. The plants are planted by transplanting. We take 60cm-80cm wet plants and cut them to a height of 50cm. The plant spacing is 2.5cm-3.0cm, the roots are interlaced and planted in the ditch, covered with soil, watered enough, and watered again the next day. After the...

Example Embodiment

[0017] Example 2

[0018] Such as figure 2 As shown, the trench excavated on the slope in this embodiment is fish-scale, and wet plants such as chinensis and tamarisk are planted by cuttings in the trench. The plant spacing of the wet plants is 1.5cm—2.0cm, and the cuttings are 30cm long, and are inserted into the soil. 20cm. The cutting date is March 10-20, the south of the Yangtze River can be advanced appropriately (March 10), and the north of the Yangtze River can be postponed appropriately (March 20). Plant high-density wet plants in the ditch, cover with soil, water enough water, and water again the next day. After the water penetrates into the soil layer, cover with soil as a ridge, the ridge height is 20cm--30cm. Cut it once in the autumn of the first year. During the 15th-20th of August, lightly cut it 30cm-35cm above the ground. After the first year, it can be cut twice a year, early spring on March 10-15 or at the turn of autumn and winter on November 15-30, re-cut to ...

Abstract

The invention provides a protection method for an inclined slope on a river bank of a quasi ecological lake. Ditches are dug on the sloping surface of the inclined slope on the river bank and made to be lengthways and widthways connected to form a network shape, each ditch has a width of 30 cm to 40 cm and a depth of 25 cm to 30 cm. For an inclined slope on a river bank made of sandy soil, the area in a shell frame formed among the ditches is from 3m to 4m. For an inclined slope on a river bank made of viscous soil, the area in a shell frame formed among the ditches is from 5m to 6m. A mode of permanent planting with high density is adopted, hygrophytes are planted in the ditches, cover plants are planted in the shell frame formed among the ditches, and emergent aquatic plants and submerged plants are planted at the lower part of the sloping surface. The invention has simple construction and low cost, can have the action for preventing flushing and protecting an earth mound, is propitious to conserve water and soil and lower the sloping surface flushing degree, provides the living environment for animals, plants and microorganisms, enables the ecological system on the sloping bank to keep stable, and has the action for beautifying the environment.

Description

technical field [0001] The invention relates to a protection method for quasi-ecological embankment slopes of lakes and rivers, and belongs to the technical field of ecological embankment protection slopes. Background technique [0002] Bank embankment, also known as revetment or bank belt, was originally defined as a vegetation area on land that interacts with water flow. The bank slope is mainly composed of three parts, namely the top, the slope and the foot of the slope. Among them, the top of the slope belongs to the terrestrial ecosystem, the foot of the slope is not underwater all the year round, and is part of the river ecosystem, while the slope surface is the transition zone of the water and land ecosystem, that is, the water and land ecotone, which has the dual characteristics of the water and land ecosystem and function. [0003] The embankment slopes of lakes and rivers are lush plants in the waterfront area, providing habitats for river amphibians, insects and...
