Description

Technical Field

[0001] The present invention relates to marine ecological restoration projects, and specifically to a method for spatial configuration and ecological protection of salt marsh vegetation on muddy coasts. Background Art

[0002] With the increasing demand for land resources in coastal areas, in order to meet this demand, high-tide reclamation projects have been widely carried out in coastal areas. However, such engineering activities inevitably lead to a significant reduction in the area of muddy tidal flats, which in turn causes serious damage to the marine ecological environment. As a transitional zone between the ocean and the land, the degradation of the ecological functions of muddy shorelines not only affects the habitats of marine organisms but also exacerbates the problem of coastline erosion, posing a threat to the ecological security and sustainable development of coastal areas.

[0003] Traditional muddy shoreline structures are relatively simple, mainly consisting of salt flats or only having a single type of salt marsh vegetation. Although these simple ecosystem structures provide a living environment for intertidal marine organisms to a certain extent, their ecological service functions are limited and cannot provide effective protection for the area behind the shoreline. Especially when facing the impact of waves and tides, single salt marsh vegetation is often difficult to resist, resulting in damage to the vegetation community and further erosion of the shoreline. Therefore, how to solve this problem has become an urgent problem to be solved at the present stage. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for spatial configuration and ecological protection of salt marsh vegetation on muddy coasts to solve the above problems.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0009] The ground on the side of the muddy shoreline facing the ecological protection embankment and in the area between the muddy shoreline and the ecological protection embankment is paved with a composite geotextile module;

[0010] The composite geotextile module includes a grid-shaped geotextile and injection-molded cone rods. The injection-molded cone rods are inserted into the muddy beach from the meshes of the geotextile, and the geotextile is consolidated by a negative pressure component fixedly installed at the end of the injection-molded cone rods.

[0011] Preferably, the artificial tidal pool includes at least three tidal pool positions, and the three tidal pool positions increase in height from the Suaeda salsa planting area towards the muddy beach.

[0012] It also includes a wave blocking part fixedly arranged on one side of the artificial tidal pool adjacent to the Suaeda salsa planting area.

[0013] The wave-facing surface of the wave blocking part is divided into an inclined surface part and an arc part according to its structure, and the end face of the first-level tidal pool position is at the same horizontal plane as the arc top of the arc part.

[0014] A triangular flow blocking part is fixedly arranged on the inclined surface part. A plurality of water return through grooves are arranged on the triangular flow blocking part in a linear array distribution. The water return through grooves are parallel to the inclined surface part. The water return through grooves are divided into a wide mouth and a narrow mouth according to their structure, and the wide mouth is distributed towards the arc part.

[0015] Preferably, a gap flow groove extending to the arc top is arranged at the end of the arc part, and each gap flow groove is distributed between two water return through grooves.

[0016] The cross section of the gap flow groove is an isosceles trapezoid, and the lower bottom of the isosceles trapezoid faces the first-level tidal pool position.

[0017] Preferably, a backflow channel fitting the ground is arranged on the inclined surface part. There is also a cobblestone pile layer distributed at the bottoms of the three tidal pool positions, and the backflow channel is communicated with the cobblestone pile layer.

[0018] Vertical shafts communicated with the cobblestone pile layer are respectively arranged at the bottoms of the three tidal pool positions, and the vertical shafts are filled with a stream stone pile layer.

[0019] Preferably, the ecological protection revetment is an inclined slope revetment built by piling up rubble stones.

[0020] The muddy beach is divided into a first sealed pile and a second sealed pile symmetrically distributed about the center of the first sealed pile according to its structure.

[0021] The top of the first sealed pile is a plane, while the top of the second sealed pile is an arc top, and the top of the arc top is at the same horizontal plane as the center point of the first sealed pile.

[0022] The composite geotextile module is laid on the side of the first embankment and the outer side of one of the second embankments, and a steel cable tensioning member is arranged between the top of the arc top of the second embankment and the ecological protection embankment bank;

[0023] The geomembrane bag stack covers the composite geotextile module, and the horizontal plane formed at the top is at the same horizontal plane as the top of the first embankment.

[0024] Preferably, the negative pressure component is a precast concrete member, and is divided into an insertion part, an extended insertion part and an extended slot part according to the structure;

[0025] The slot opened on the extended slot part is inserted into the convex part opened on the end face of the extended insertion part.

[0026] Preferably, a perfusion interface pipe is opened on the extended insertion part, and the perfusion interface pipe is communicated with a grouting pipe fixedly arranged in the extended slot part;

[0027] The insertion part is inserted into the injection cone rod member, the inside of the injection cone rod member is a hollow structure, and the hollow structure is communicated with the grouting pipe.

[0028] Preferably, a positioning member is further included. The positioning member is inserted from the insertion part, extends into the hollow structure of the injection cone rod member, and is finally inserted and fixed with the bottom of the hollow structure;

[0029] A predetermined distance is maintained between the side wall of the positioning member and the hollow structure, and a spiral groove is opened on the side wall of the positioning member.

[0030] Preferably, a window is opened on the outer wall of the injection cone rod member, and a sealing plate is rotatably connected in the window. A channel for communicating the hollow structure with the window is opened in the injection cone rod member;

[0031] The maximum flipping angle of the sealing plate is 25° - 35°, the number of windows is several, and they are arranged in a spiral curve array along the outer wall of the injection cone rod member.

[0033] S01. As the tide rises, the tide successively covers the hibiscus planting area, the reed planting area, the salt marsh plant planting area and the suaeda salsa planting area;

[0034] S02. When the tide continues to rise, it extends to the three tidal pond positions of the artificial tidal pond to carry out stepped drainage of the tide;

[0035] S03. As the tide continues to rise, the tide flows downstream within the third-level tidal pool, and then gradually spreads to submerge the muddy beach. The geotextile bag piles are located between the muddy beach and the ecological protection embankment.

In addition, the layout of the civil air defense works system can improve the wave dissipation and wave reduction ability of the beach, and enhance the disaster reduction ability of the intertidal ecosystem;

[0038] The artificial tidal pool is built with block stones. The block stone structure can imitate the roughness and multi-porous characteristics of natural rock coasts, which is beneficial to enrich the biodiversity of the intertidal zone of muddy coasts. In addition, the height of the artificial tidal pool is lower than that of the ecological submerged dyke. When waves and storm surges come, the ecological protection structure at the front of the salt marsh vegetation on the muddy coast can play a role in wave dissipation and current weakening; when the tide ebbs, the ecological protection embankment can also play a role in storing and retaining the tide and delaying the ebb of the tide, providing a good habitat and living environment for the intertidal marine organisms on the muddy coast, and being beneficial to the restoration of the intertidal ecosystem of the muddy coast.

Detailed implementation manners

[0049] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0050] As Figures 1 - 7 shown, a spatial configuration of salt marsh vegetation on a silty coast includes:

[0051] An artificial beach belt system, which is successively provided with a Hibiscus planting area 1, a Reed planting area 2, a Salt marsh plant planting area 3, and a Suaeda salsa planting area 4 from the coastal beach to the inland;

[0052] A civil air defense works system, which includes an artificial tidal pool 5, a silty beach 6, and an ecological protection embankment 7, and a geomembrane bag stack 10 is stacked in the area between the silty beach 6 and the ecological protection embankment 7, wherein:

[0053] The ground on one side of the silty beach 6 facing the ecological protection embankment 7 and in the area between the silty beach 6 and the ecological protection embankment 7 is paved with a composite geotextile module 8;

[0054] The composite geotextile module 8 includes a grid-shaped geotextile 81 and an injection molding taper rod member 83 (a corrosion-resistant plastic part). The injection molding taper rod member 83 passes through the geotextile 81 mesh into the silty beach 6 and consolidates the geotextile 81 through the negative pressure component 82 fixedly installed at its end.

[0055] Specifically, the geotextile bag stack 10 is stacked on the geotextile 81 and is located between the muddy shore beach 6 and the ecological protection revetment 7. And the geotextile 81 has a strength of 50 kN / m and is filled with soil inside.

[0056] The ecological protection revetment 7 is constructed by piling up stones with a single weight greater than 100 kg using concrete.

[0057] Furthermore, the distance between the artificial tidal pool 5 and the Suaeda salsa planting area 4 in the above embodiment is greater than 20 m and less than 100 m.

[0058] Secondly, the artificial beach zone system can provide a habitat for marine organisms. Specifically, assuming that the average low tide level and high tide level in the sea area where the embodiment of the present invention is located are L meters and H meters respectively, the elevation of the top surface of the artificial beach zone in this area can be controlled around 0.5 m above the mean tide level. And the seaward sides of the Hibiscus syriacus planting area 1, the Phragmites australis planting area 2, the salt marsh plant planting area 3, and the Suaeda salsa planting area 4 can be set in an arc shape, a strip shape, or a continuous wavy shape.

[0059] In the above technology, the artificial beach zone system is set as the Hibiscus syriacus planting area 1, the Phragmites australis planting area 2, the salt marsh plant planting area 3, and the Suaeda salsa planting area 4 according to the terrain changes, so as to provide a good shelter, foraging, and habitat environment for intertidal marine organisms, and also provide a good foraging place for birds. In addition, the layout of the civil air defense works system can improve the wave dissipation and wave reduction ability of the shore beach and enhance the disaster reduction ability of the intertidal ecosystem;

[0060] The artificial tidal pool 5 is built by piling up stones. The stone structure can imitate the roughness and porous characteristics of the natural rock coast, which is beneficial to enrich the biodiversity of the intertidal zone of the muddy coast. In addition, the height of the artificial tidal pool 5 is lower than that of the ecological submerged dike. When waves and storm surges come, the ecological protection structure at the front of the salt marsh vegetation on the muddy coast can play a role in dissipating waves and weakening currents. When the tide ebbs, the ecological protection revetment 7 can also play a role in storing and retaining the tide and delaying the ebb of the tide, providing a good habitat and living environment for the intertidal marine organisms of the muddy coast and being beneficial to the restoration of the intertidal ecosystem of the muddy coast.

[0061] As a further embodiment provided by the present invention, as shown in combination with Figure 3 and Figure 4 the artificial tidal pool 5 includes at least three tidal pool positions 51, and the three tidal pool positions 51 increase in height from the Suaeda salsa planting area 4 towards the muddy shore beach 6;

[0062] It also includes a wave blocking part 52 fixedly arranged on one side of the artificial tidal pool 5 adjacent to the Suaeda salsa planting area 4;

[0063] The tide-facing surface of the wave-blocking part 52 is divided into an inclined surface part 521 and an arc part 522 according to its structure, and the end face of the pool mouth of the first-level tide pool 51 is at the same horizontal level as the top of the arc of the arc part 522;

[0064] A triangular flow-blocking part 53 is fixedly arranged on the inclined surface part 521. A plurality of water-return through grooves 531 distributed in a linear array are formed on the triangular flow-blocking part 53. The water-return through grooves 531 are parallel to the inclined surface part 521. The water-return through grooves 531 are divided into wide mouths and narrow mouths according to their structures, and the wide mouths are distributed towards the arc part 522.

[0065] Furthermore, in combination with Figure 4 As shown, a gap flow groove 5221 extending to the top of the arc is formed at the end of the arc part 522, and each gap flow groove 5221 is distributed between two water-return through grooves 531. The cross-section of the gap flow groove 5221 is an isosceles trapezoid, and the lower base of the isosceles trapezoid faces the first-level tide pool 51.

[0066] Specifically, the tide pool 51 in the above embodiment can be a precast concrete member or be built by piling up rubble stones. The rubble stone structure can imitate the roughness and multi-porous characteristics of a natural rock coast. And the artificial tide pool 5 in this example includes at least three tide pools 51. The height of the artificial tide pool 5 is lower than the height of the ecological submerged dyke. When waves and storm surges come, the ecological protection structure at the front of the salt marsh vegetation on the muddy coast can play a role in wave dissipation and current weakening; when the tide ebbs, the ecological protection revetment 7 can also play a role in storing and retaining the tide water and delaying the ebb of the tide water, providing a good habitat and living environment for marine organisms in the intertidal zone of the muddy coast, which is beneficial to the restoration of the intertidal zone ecosystem of the muddy coast.

[0067] Secondly, the triangular flow-blocking part 53 and the inclined surface part 521 in the embodiment cooperate to block the impact force of the waves, thereby reducing the impact force of the waves on the tide pool 51. Moreover, the water-return through grooves 531 and the gap flow grooves 5221 in the embodiment cooperate to form a scouring system, which can avoid the formation of dead corners and accumulations caused by the wave-blocking design of the triangular flow-blocking part 53 and the inclined surface part 521, so that the fish and shrimp running here with the waves can return to the water.

[0068] As another embodiment further provided by the present invention, in combination with Figure 3 and Figure 4 As shown, a backflow channel 5211 fitting the ground is formed on the inclined surface part 521, and a cobblestone pile layer 523 distributed at the bottoms of the three tide pools 51 is further included. The backflow channel 5211 is communicated with the cobblestone pile layer 523. Furthermore, vertical shafts 524 communicated with the cobblestone pile layer 523 are respectively formed at the bottoms of the three tide pools 51, and the vertical shafts 524 are filled with a stream stone pile layer.

[0069] Specifically, there are also some reverse flow channels 5211 on the inclined surface part 521, and these reverse flow channels 5211 are connected to the cobblestone pile layers 523 at the bottoms of the three tidal pool positions 51. Vertical shafts 524 are also opened at the bottoms of the tidal pool positions 51, which are filled with stream stones and are communicated with the cobblestone layer. The above structures can enhance the water circulation of the tidal pool positions 51, improve water quality, and at the same time provide a richer ecological environment for salt marsh vegetation.

[0070] As yet another embodiment further provided by the present invention, in combination with Figure 2 as shown, the ecological protection embankment 7 is an inclined slope protection embankment built by piling up rubble stones;

[0071] The muddy shore beach 6 is divided into a first sealed pile 61 and a second sealed pile 62 that is symmetrically distributed about the center of the first sealed pile 61 according to its structure;

[0072] The top of the first sealed pile 61 is a plane, while the top of the second sealed pile 62 is an arc top, and the top of this arc top is on the same horizontal plane as the center point of the first sealed pile 61;

[0073] The composite geotextile module 8 is laid on the side of the first sealed pile 61 and the outer side of one of the second sealed piles 62, and a steel cable tensioning member 9 is arranged between the top of the arc top of the second sealed pile 62 and the ecological protection embankment 7;

[0074] The geotextile bag pile 10 covers the composite geotextile module 8, and the horizontal plane formed at the top is on the same horizontal plane as the top of the first sealed pile 61.

[0075] Specifically, the ecological protection embankment 7 is an inclined slope protection embankment piled up with stones, and the muddy shore beach 6 is divided into two symmetrical parts: the first sealed pile 61 has a flat top, and the second sealed pile 62 has an arc-shaped top. The tops of these two parts are on the same horizontal line. The composite geotextile module 8 is laid on the flat top and the outer side of the arc on one side, and on the other side, between the arc top and the ecological protection embankment 7, it is reinforced with a steel cable tensioning member 9. The geotextile bag pile 10 covers the geotextile 81, and its top is also on the same horizontal plane as the flat top. This greatly enhances the stability of the shore beach, prevents soil erosion, and at the same time provides a solid foundation for the growth of salt marsh vegetation.

[0076] As yet another embodiment further provided by the present invention, in combination with Figure 6 and Figure 7 as shown, the negative pressure component 82 is a precast concrete member, and is divided into an insertion part 821, an extended insertion part 822, and an extended slot part 823 according to its structure;

[0077] The slot opened on the extended slot part 823 is inserted with the convex part opened on the end surface of the extended insertion part 822.

[0078] Furthermore, a perfusion interface pipe 824 is provided on the extended insertion part 822, and the perfusion interface pipe 824 communicates with a grouting pipe 825 fixedly arranged in the extended slot part 823;

[0079] The insertion part 821 is inserted into the injection-molded tapered rod member 83. The inside of the injection-molded tapered rod member 83 is a hollow structure, and the hollow structure communicates with the grouting pipe 825.

[0080] Secondly, it further includes a positioning member 84. The positioning member 84 is inserted into the injection-molded tapered rod member 83 from the insertion part 821, extends into the hollow structure of the injection-molded tapered rod member 83, and is finally inserted and fixed to the bottom of the hollow structure;

[0081] A predetermined distance is maintained between the side wall of the positioning member 84 and the hollow structure, and a spiral groove 841 is provided on the side wall of the positioning member 84.

[0082] Specifically, during construction, the geotextile 81 is pre-laid as Figure 2 shown, and then one side of the geotextile 81 is fixed by driving a concrete column into the top of the first seal pile 61.

[0083] Furthermore, the negative pressure component 82 applies negative pressure to the geotextile 81, that is, the extended insertion part 822 and the extended slot part 823 cover the geotextile 81, while the insertion part 821 is distributed at the center of the mesh holes of the geotextile 81 grid. Then the injection-molded tapered rod member 83 is inserted through the central hole on the insertion part 821 and implanted into the silty beach 6. Then the positioning member 84 is passed through the insertion part 821 and implanted into the hollow structure of the injection-molded tapered rod member 83. At this time, the concrete slurry is sucked by a sludge pump and then poured into through the perfusion interface pipe 824, and finally reaches the hollow structure of the injection-molded tapered rod member 83 along the grouting pipe 825, enhancing the integrity.

[0084] As yet another embodiment further provided by the present invention, in combination with Figure 6 and Figure 7 shown, a window is provided on the outer wall of the injection-molded tapered rod member 83, and a sealing plate 85 is rotatably connected in the window. A channel is provided in the injection-molded tapered rod member 83 to communicate the hollow structure with the window; and the maximum flipping angle of the sealing plate 85 is 25° - 35°, and the number of windows is several, and they are arrayed along a spiral curve on the outer wall of the injection-molded tapered rod member 83.

[0085] Specifically, after the concrete slurry in the above embodiment reaches the hollow structure of the injection-molded tapered rod member 83 along the grouting pipe 825, the concrete slurry will rotate and flow due to the spiral groove 841, and then the concrete slurry enters the window through the channel and pushes the sealing plate 85 to open, so that the concrete slurry pours into the silty beach 6, enhancing its overall stability and durability.

[0086] The ecological protection method based on the spatial configuration of the above-mentioned muddy coastal salt marsh vegetation includes the following steps:

[0087] S01. As the tide increases, the tide will successively flood the hibiscus planting area 1, the reed planting area 2, the salt marsh plant planting area 3 and the saltwort salsa plant planting area 4;

[0088] S02, when the tide continues to rise, the three tide pools 51 extending to the artificial tide pool 5 are stepped to discharge the tide;

[0089] S03. As the tide continues to rise, the tide flows down from the third-level tidal pool 51 and then gradually floods the muddy beach 6, while the geobag pile 10 is located between the muddy beach 6 and the ecological protection pile bank 7.

[0090] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
