Embodiment 1

[0016] Such as figure 1 As shown, in the quasi-ecological embankment slope of the lake and river constructed by the present invention, the embankment adopts a combination of embankment and road, the embankment body is a homogeneous earth dam, and the bank revetment is constructed above the paved layer of the river bed. The ditch excavated on the slope is grid-like, the width of the ditch is 30cm-40cm, and the depth is 25cm-30cm. For slopes with sandy soil, the area within the frame formed between the ditches is 3m 2 ~4m 2 , for slopes with cohesive soils, this area can be appropriately increased to 5m 2 ~6m 2 . Such as image 3 As shown, wet plants such as willow and tamarix are planted in each ditch by high-density root system interlaced colonization. Planting adopts the method of transplanting. Wet plants of 60cm--80cm are taken and cut to a height of 50cm. The distance between the plants is 2.5cm-3.0cm. After the roots are interlaced, they are planted in the ditch, co...

Embodiment 2

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

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...
