Problems solved by technology

This utility model is mainly to weaken the non-point source pollution entering the reservoir, purify the water quality around the reservoir, and reduce soil erosion and sedimentation caused by bank slope collapse in the water-fluctuating zone. The realization of water purification is still not deep enough.

Embodiment 1

[0038] A combination planting system of coastal plants adapted to water level changes, combined with Figure 1 ~ Figure 2 To illustrate, in the direction perpendicular to the shore, a grass planting area 3, an emergent plant area 2, and several ecological floating beds 1 are arranged in sequence; the plants in the ecological floating bed 1 are emergent plants, which are a combination of barracuda, Alisma, and canna , the distance between two adjacent ecological floating beds 1 is 5m; the distribution range of emergent plant zone 2 is the bank slope between the lowest water level and the highest water level of the river and lake, and the plants in emergent plant zone 2 are wet Emerging plants are a combination of calamus, mosaic reed, and cattail; the distribution range of the grass planting area 3 is the area between the highest water level of the river and lake to the top of the bank, and the plants in the grass planting area 3 are humidity-tolerant grasses. It is clover, and...

Embodiment 2

[0040] This embodiment is further optimized on the basis of embodiment 1, combining Figure 3 ~ Figure 5 To illustrate, the ecological floating bed 1 includes a box frame 4 without a cover, and the box frame 4 without a cover includes a bottom plate 401, a front panel 402 away from the shore, a rear panel 403 close to the shore, and two side panels 404 perpendicular to the shore, The front panel 402 is semicircular; the coverless box frame 4 is provided with a water permeable hole 405, and the coverless box frame 4 is provided with a foam floating tank 5; wherein, the diameter of the front panel 402 is the same as the length of the rear panel 403, Both are 2.5m; the widths of the two side plates 404 are both 0.4m.

[0041] The foam floating tank 5 is a porous foam tank, and the both sides of the upper surface of the foam floating tank 5 are respectively provided with a groove 20 for binding, and utilize soft ropes to bind the foam floating tank 5 on the base plate 401; A subs...

Embodiment 3

[0043] This embodiment is further optimized on the basis of embodiment 2, combining Figure 6 ~ Figure 7 To illustrate, the connecting rod system 6 is made up of a concrete pile 7, a base 8, a connecting rod 9, and a floating bed connecting bracket 10, and the connecting rod 9 includes a main rod 13, a base connecting end 14 of a vertical main rod 13, and a connecting rod 13 of the vertical main rod 13. The connection end 15 of the floating bed, the length L of the main pole 13, the maximum flood level Hmax of the river and lake, the minimum water level Hmin of the river and lake, and the bank slope ratio i satisfy the following relationship: Among them, the bank slope ratio i is the ratio between the vertical height h and the horizontal width l of the slope of the emergent plant area 2, that is, the tangent value of the slope angle; the concrete pile 7 is the lower end fixed on the emergent plant area 2 with a cone point The cylinder, the concrete pile 7 is buried in the dis...

Abstract

The invention discloses a coastal zone plant combination planting system adaptive to water level change. The coastal zone plant combination planting system adaptive to water level change comprises a grass planting area, an emergent aquatic plant area and several ecological floating beds, which are arranged in sequence; the grass planting area is composed of an area between the highest water levelof a river or lake and a shore top; the emergent aquatic plant area is composed of a bank slope between the lowest water level of the river or lake and the highest water level; and the moving direction and the moving range of the ecological floating beds are limited through a connecting rod system fixed in the emergent aquatic plant area. According to the coastal zone plant combination planting system adaptive to water level change in the invention, due to the three-stage water purification system including ecological floating beds, the emergent aquatic plant area and the grass planting area,coastal zone runoff sediment and water body pollutants can be effectively decreased; the flow direction and the flow speed of a water body in a coastal zone also can be changed; therefore, the systemis adaptive to water level change of the river or lake; and dissolved oxygen of the water body in the coastal zone is increased. The coastal zone plant combination planting system adaptive to water level change in the invention is simple in structure; the shape of the coastal zone is not changed; assembly type construction is easily carried out; the landscape effect is good; and simultaneously, the coastal zone plant combination planting system adaptive to water level change also has the advantages of being low in construction cost and convenient to popularize.

Description

technical field [0001] The invention belongs to the technical field of water body ecological restoration and river and lake water quality purification, and in particular relates to a combined planting system for coastal zone plants adapted to water level changes. Background technique [0002] The pollution control of rivers and lakes has always been the focus and difficulty in the construction of water ecological civilization. Rainfall runoff, farmland receding water and other sewage discharges can easily lead to the accumulation of pollutants in the water environment, which will continuously aggravate the pollution of water bodies, causing Deterioration of water environment such as water eutrophication and degradation of water biodiversity. Biological measures are widely used in water pollution control because of their environmental friendliness and easy maintenance. It is a method that uses aquatic organisms to absorb and utilize nitrogen, phosphorus and other elements for...
