Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology. More specifically, this invention relates to a rhomboid-shaped ecological buffer zone and its construction method. Background Technology

[0002] Rainwater runoff carries pollutants from the ground and soil into surface water bodies, leading to a deterioration of water quality. Establishing a diamond-shaped ecological buffer zone composed of trees, grasses, and shrubs between water bodies and land is an effective means of intercepting pollutants from rainwater runoff and protecting the water environment. However, in existing diamond-shaped ecological buffer zones, the plant layers are arranged in a straight line, resulting in clogging and low utilization rates due to prolonged interception in a single direction. Therefore, it is necessary to design a technical solution that can overcome these shortcomings to some extent. Summary of the Invention

[0003] One objective of this invention is to provide a rhomboid-shaped ecological buffer zone and its construction method, which can alleviate clogging of the vegetation layer and improve the utilization rate of the vegetation layer.

[0004] To achieve these objectives and other advantages of the present invention, according to one aspect of the present invention, a rhomboid ecological buffer zone is provided, comprising multiple rhomboid regions covering a slope, the multiple rhomboid regions being seamlessly connected to each other, the multiple rhomboid regions forming low-lying areas near their four sides, the multiple rhomboid regions comprising at least a tree and grass layer, a shrub and grass layer and a pebble layer from top to bottom, the rhomboid regions contained in the tree and grass layer, the shrub and grass layer and the pebble layer being approximately at the same height, the rhomboid regions of the pebble layer being filled with pebbles, the rhomboid regions of the tree and grass layer being planted with *Cymbidium* plants, and the rhomboid regions of the shrub and grass layer being planted with shrub and grass plants.

[0005] Furthermore, it also includes: a water collection ditch, which is disposed above the plurality of said rhomboid areas and along the length direction of said slope.

[0006] Furthermore, it also includes a purification layer disposed below the plurality of said rhomboid regions, wherein functional aquatic plants are planted within the purification layer.

[0007] Furthermore, the two axes of symmetry of the rhombus containing the rhombus region are approximately along the length direction of the slope and perpendicular to the length direction of the slope, respectively.

[0008] Furthermore, the apex angle of the rhombus facing upwards toward the slope is 80 to 120 degrees.

[0009] Furthermore, a wire mesh cage matching the rhomboid region is provided within the pebble layer, and the pebbles are filled in the wire mesh cage.

[0010] According to another aspect of the present invention, a method for constructing a rhomboid ecological buffer zone is also provided, comprising: S1: measuring the slope; S2: designing rhomboid regions according to the size of the slope, such that multiple rhomboid regions can be seamlessly spliced ​​together to cover the slope; S3: dividing the multiple rhomboid regions into at least a tree and grass layer, a shrub and grass layer, and a pebble layer from top to bottom according to height, wherein the rhomboid regions contained in the tree and grass layer, the shrub and grass layer, and the pebble layer are approximately at the same height, filling the rhomboid regions in the pebble layer with pebbles, planting *Cyperus rotundus* in the rhomboid regions of the tree and grass layer, and planting shrubs and grasses in the rhomboid regions of the shrub and grass layer.

The multiple rhomboid areas include at least a layer of trees and grasses, a layer of shrubs and grasses, and a layer of pebbles from top to bottom. Each rhomboid area can receive rainwater from at least two directions, thereby alleviating blockage within the rhomboid area and achieving rainwater interception from two directions, while also improving the utilization rate of plants or pebbles within the rhomboid area.

[0017] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of a rhomboid region structure according to an embodiment of this application. Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0021] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0022] like Figures 1-2 As shown, embodiments of this application provide a rhomboid-shaped ecological buffer zone, including multiple rhomboid areas covering the slope. The multiple rhomboid areas are seamlessly connected to each other, and the multiple rhomboid areas form a low-lying area 201 near the four sides. The multiple rhomboid areas include at least a tree and grass layer (2, 3, 4), a shrub and grass layer (5, 6), and a pebble layer 7 from top to bottom. The rhomboid areas contained in the tree and grass layer (2, 3, 4), the shrub and grass layer (5, 6), and the pebble layer 7 are approximately at the same height. The rhomboid areas in the pebble layer 7 are filled with pebbles. The rhomboid areas in the tree and grass layer (2, 3, 4) are planted with grass plants, and the rhomboid areas in the shrub and grass layer (5, 6) are planted with shrubs and grasses.

[0023] In the above embodiments, the slope refers to the slope of a river or lake, which has a certain inclination. The entire slope is covered by rhomboid areas, with no gaps or small gaps between the rhomboid areas. The arc-shaped areas near the four sides of the rhomboid areas form low-lying areas 201, while the center and the areas near the four corners form raised areas (202, 203), so that rainwater enters from two sides of the rhomboid area as much as possible and flows out from the other two sides. Preferably, the height of the center is slightly higher than the low-lying area 201, such as 5-10 cm higher, and slightly lower than the four corners by 10-15 cm, so that rainwater can more easily enter another low-lying area 201 through the center without reaching the raised areas. See [reference needed]. Figure 2Preferably, the raised areas (202, 203) and the low-lying areas 201 transition smoothly; the tree and grass layer (2, 3, 4), the shrub and grass layer (5, 6), and the pebble layer 7 each include multiple rhomboid areas at the same height, with the height decreasing sequentially; the pebble layer 7 is composed of pebbles stacked within the corresponding rhomboid areas, used to filter large particles of rainwater and slow down the flow rate of rainwater; the tree and grass layer (2, 3, 4) is planted with trees such as metasequoia and mulberry, and the shrub and grass layer (5, 6) is planted with shrubs such as paper mulberry and iron holly; the gaps between the trees and shrubs are filled with herbaceous plants such as foxtail grass and tall fescue to reduce space waste; the tree and grass layer (2, 3, 4) Due to the low-lying area 201 and the raised area of ​​the rhomboid region, rainwater can more easily flow in from the two sides of the rhomboid region. This allows the tree and grass layer (2, 3, 4), the shrub and grass layer (5, 6), and the pebble layer 7 to intercept rainwater from two directions, avoiding long-term interaction with rainwater in the same direction. This improves the utilization rate of plants or pebbles. Moreover, when one direction is blocked or clogged by mud or other impurities, the rainwater flow in the other direction can wash away the mud or other impurities to a certain extent, reducing the possibility of plants or pebbles being blocked in the tree and grass layer (2, 3, 4), the shrub and grass layer (5, 6), and the pebble layer 7.

[0024] Optionally, the tree and grass layers (2, 3, 4) can have multiple layers, and each layer (2, 3, 4) can be planted with the same or different trees, so that the width of the tree and grass layers (2, 3, 4) meets the requirements, such as... Figure 1 It has three layers of trees and grasses (2, 3, 4);

[0025] Optionally, the shrub and grass layers (5, 6) can have multiple layers, each layer (5, 6) can be planted with the same shrubs, so that the width of the shrub and grass layers (5, 6) meets the requirements, or each layer (5, 6) can be planted with shrubs of different planting densities and different planting depths, such as... Figure 1 It has two layers of shrubs and grasses (5, 6);

[0026] Optionally, the two axes of symmetry of the rhombus containing the rhombus are approximately along the length of the slope and perpendicular to the length of the slope, respectively. That is, the two adjacent sides of the rhombus containing the rhombus are used to collect rainwater from above the slope, and then the rainwater flows out from the other two adjacent sides.

[0027] Optionally, the apex angle of the rhombus facing the slope is 80 to 120 degrees. This angle range allows for a larger angle between the two inflow directions of rainwater, enabling full utilization of both directions of vegetation or pebbles.

[0028] As can be seen, this embodiment utilizes rhomboid regions to construct a tree and grass layer (2, 3, 4), a shrub and grass layer (5, 6), and a pebble layer 7. By specially designing the rhomboid regions, each rhomboid region can receive rainwater from at least two directions, thereby alleviating blockage within the rhomboid regions and achieving rainwater interception from two directions, while also improving the utilization rate of plants or pebbles within the rhomboid regions.

[0029] In another embodiment, it further includes: a water collection ditch 1, which is disposed above the plurality of rhomboid areas and along the length of the slope; the water collection ditch 1 is used to initially collect rainwater and then allow it to flow into the plurality of rhomboid areas, thereby reducing the disorder of rainwater and improving the interception effect of rainwater; preferably, the rhomboid areas of the uppermost layer of grass 2 extend into the water collection ditch to facilitate the entry of rainwater from two adjacent sides of the rhomboid areas.

[0030] In another embodiment, it also includes a purification layer 8, which is disposed below the plurality of rhomboid regions. The purification layer 8 is planted with functional aquatic plants, including aquatic canna, reed, and yellow iris, which act as wetlands to purify rainwater and reduce the pollution of river and lake water by heavy metals and other pollutants.

[0031] In another embodiment, a wire mesh cage matching the rhomboid region is provided within the pebble layer 7, and the pebbles are filled in the wire mesh cage; optionally, the wire mesh cage is a wire frame set at the edge of the rhomboid region to prevent the pebbles from tipping over.

[0032] Embodiments of this application also provide a method for constructing a rhomboid-shaped ecological buffer zone, including:

[0033] S1: Measure the slope to determine its length, width, and gradient;

[0034] S2: Design rhomboid regions according to the dimensions of the slope, so that multiple rhomboid regions can be seamlessly spliced ​​together to cover the slope; the size and distribution of the rhomboid regions need to match the tree and grass layer (2, 3, 4), shrub and grass layer (5, 6), and pebble layer 7, and in accordance with... Figure 2 Delineate the uplifted and low-lying areas;

[0035] S3: Divide the multiple rhomboid regions from top to bottom into at least a tree and grass layer (2, 3, 4), a shrub and grass layer (5, 6), and a pebble layer 7 according to their height. The rhomboid regions contained in the tree and grass layer (2, 3, 4), the shrub and grass layer (5, 6), and the pebble layer 7 are at approximately the same height. Construction is carried out on each rhomboid region to form a low-lying area 201 near the four sides, and a raised area (202, 203) at the center and near the four corners. Then, pebbles are filled into the rhomboid regions of the pebble layer 7. Bridge grass plants are planted in the rhomboid regions of the tree and grass layer (2, 3, 4), and shrubs and grasses are planted in the rhomboid regions of the shrub and grass layer (5, 6), thus realizing the construction of a rhomboid ecological buffer zone.

[0036] In another embodiment, the method further includes: setting up a water collection ditch 1, which is located above the plurality of rhomboid areas and extends along the length of the slope, with the rhomboid areas of the uppermost grass layer 2 extending into the water collection ditch; the water collection ditch 1 is used to initially collect rainwater and then allow it to flow into the plurality of rhomboid areas, thereby reducing the disorder of rainwater and improving the interception effect of rainwater.

[0037] In another embodiment, the method further includes: setting a purification layer 8, which is located below the plurality of rhomboid regions, and planting functional aquatic plants, including aquatic canna, reed, and yellow iris, in the purification layer to act as a wetland, purify rainwater, and reduce the pollution of river and lake water by heavy metals and other pollutants.

[0038] In another embodiment, the two axes of symmetry of the rhombus containing the rhombus region are approximately along the length of the slope and perpendicular to the length of the slope, respectively, and the apex angle of the rhombus facing upwards from the slope is 80 to 120 degrees. That is, two adjacent sides of the rhombus containing the rhombus region are used to collect rainwater from above the slope, and then the rainwater flows out from the other two adjacent sides. The 80 to 120 degree angle range makes the two inflow directions of rainwater relatively large, allowing both directions of the plants or pebbles to be fully utilized.

[0039] In another embodiment, a wire mesh cage matching the rhomboid region is provided within the pebble layer 7, and the pebbles are filled in the wire mesh cage; optionally, the wire mesh cage is a wire frame set at the edge of the rhomboid region to prevent the pebbles from tipping over.
