Description

Technical Field

[0001] This utility model relates to the technical field of environmental simulation and agricultural facilities, specifically a climate change simulation system for coastal tidal flat environment and intelligent regulation. Background Technology

[0002] Coastal tidal flat ecosystems, as transitional zones between land and ocean, play an irreplaceable role in global carbon cycling and biodiversity conservation. However, affected by global climate change, these regions are facing multiple pressures, including sea-level rise, temperature increases, and frequent extreme weather events. Accurately simulating and predicting the impacts of these changes on tidal flat ecosystems has become a cutting-edge topic in current ecological research. As a key interface for land-sea interaction, the environmental simulation technology for coastal tidal flat ecosystems faces unique engineering challenges and scientific requirements. Existing simulation systems have systemic defects in addressing the special environment of tidal flats, and environmental simulation technologies suffer from several key technical bottlenecks. These shortcomings severely restrict the in-depth development of research on the response of tidal flat ecosystems under the background of climate change.

[0003] The structural limitations of existing simulation systems: Traditional greenhouse systems are mainly optimized for terrestrial environments and cannot meet the special needs of coastal tidal flat environments. Specifically: 1) In terms of system structure, traditional designs fail to fully consider the dynamic characteristics of tidal flat environments, resulting in insufficient foundation stability and a lack of special consideration for periodic tidal inundation and storm surge impacts. The foundation depth of ordinary greenhouses is typically no more than 500mm. Under the soft geological conditions of tidal flats, insufficient foundation stability during storm surges leads to uneven settlement of the system on the soft tidal flat matrix. For example, during the landfall of Typhoon Bebinca, the strongest typhoon in 75 years in a certain area, the simulation system of this coastal wetland tilted by as much as 10°, severely affecting experimental data. 2) Poor material corrosion resistance: The salt spray concentration in tidal flat environments is 8-10 times that of inland areas. Ordinary carbon steel structural components, without protection, show significantly reduced durability and high corrosion rates in salt spray and high humidity environments. These structural defects directly affect the reliability of long-term experiments. The steel frames of greenhouses in typical coastal wetland stations often suffer structural damage after three years of use, with repair costs exceeding 60% of the original construction cost. 3) Low accuracy in hydrological simulation: Existing systems mostly employ fixed water level designs or periodic water storage and release, failing to simulate the periodic changes of real tides. Comparing measured tidal data, the water level control of traditional systems differs significantly from actual environmental tidal changes, resulting in large errors and insufficient capacity to meet the needs of vegetation response research.

[0004] Existing environmental control systems have significant limitations when applied to tidal flat simulations: difficulties in multi-parameter coordination. Tidal flat ecosystems require precise simulation of complex hydrological-climate coupling processes, including the coordinated changes in tidal cycles, salinity gradients, and temperature fluctuations. Existing control systems mostly employ independent parameter adjustment modes, making it difficult to achieve dynamic coupling simulation of multiple environmental factors. In particular, gas exchange and water quality control systems suffer from response lag and uneven spatial distribution, failing to meet the precise requirements of vegetation physiological research. Therefore, current tidal flat simulation research faces three major challenges in data acquisition: 1) Lack of in-situ observation: Existing systems cannot conduct continuous monitoring under flooded conditions, resulting in significant data loss of key ecological processes. Especially when simulating storm surge events, sensor failure rates are high. 2) Unclear microscopic mechanisms: Traditional data acquisition systems lack the ability to continuously observe under tidal flooding conditions, resulting in substantial data loss of key ecological processes. At the microscale, important processes such as root development and sediment microbial activity lack effective in-situ observation methods. Furthermore, traditional methods struggle to simultaneously acquire vegetation physiological responses (such as root growth) and changes in environmental parameters. 3) Low data integration: Data generated by different subsystems has inconsistent formats, requiring extensive manual processing for analysis. Furthermore, the unique environment of coastal areas poses severe challenges to the energy system: tidal flat stations are mostly located at the end of the power grid. However, coastal areas are rich in wind and solar energy resources; therefore, this system design relies on both solar energy and battery backup, and incorporates strict water release protection. This ensures the system can operate normally even under extreme weather conditions.

[0005] Current tidal flat simulation research faces severe methodological challenges in standardization and reproducibility, which has become a key bottleneck restricting the reliability of research conclusions and their widespread application. Significant scale differences exist between small-scale laboratory simulation systems and real tidal flat ecosystems, making it difficult for simulation results to accurately reflect actual ecological processes. Specifically: First, small-scale systems cannot accommodate the complete topographic gradient of the tidal flat (including the continuous transition between high, mid, and low tide sections), artificially simplifying the spatial distribution pattern of vegetation communities. Second, small-scale systems struggle to reproduce the unique hydrological connectivity of tidal flats, particularly the crucial role of tidal channel networks in material transport and energy flow. Third, boundary effects in small-scale environments (such as lateral wall reflection and uneven artificial lighting) significantly alter microenvironmental conditions. Furthermore, short-term experiments (usually less than one year) are insufficient to capture the long-term adaptation processes of tidal flat ecosystems to climate change, especially slow-moving variables involving vegetation community succession (with a cycle typically of 5-10 years) and sedimentary geomorphological adjustments. To address these issues, there is an urgent need to establish a standardized simulation system that covers multiple spatial scales (from rhizosphere to ecosystem scale) and temporal scales (from tidal cycles to decadal scales).

[0006] In summary, these technical bottlenecks make it difficult for existing simulation systems to meet the precise requirements of climate change impact assessment and ecological restoration engineering guidance. Developing a novel coastal tidal flat environment simulation system capable of overcoming these bottlenecks has become a critical technical challenge urgently needing to be addressed in current wetland ecology research. This requires fundamentally resolving key issues such as structural adaptability, control precision, monitoring comprehensiveness, and methodological standardization to provide a reliable technical platform for related scientific research. This not only relates to the accuracy of climate change impact assessment but also directly affects the scientific validity and effectiveness of coastal ecological restoration projects. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by designing a climate change simulation system for coastal tidal flat environments and intelligent regulation. The system comprises a greenhouse structure consisting of a cement column foundation, a main greenhouse unit, a water passageway, and a storm surge stabilization device. Combined with tidal hydrological control devices, storm-resistant structural design, modular environmental regulation units, and the synergistic effect of multiple interfaces between microorganisms, plants, and the atmosphere, it achieves precise monitoring and dynamic balance regulation of greenhouse gas emissions, providing accurate environmental parameter feedback for the gas cycle process. This system rationally utilizes real tidal level changes to more realistically simulate sea-level rise under global climate change, effectively solving the technical challenges of traditional greenhouses in special coastal environments, such as insufficient wind resistance, salt spray corrosion, and tidal submersion. It is particularly suitable for simulating the combined effects of sea-level rise and temperature increase under the background of global climate change, and can be widely applied to coastal wetland ecological research, salt-tolerant crop cultivation, and intertidal vegetation restoration projects, demonstrating good application prospects and practical value.

[0011] The high tide and low tide plant culture columns are set on the tidal flats inside the greenhouse by permeable bottom covers. The high tide plant culture column is buried at a depth of 400mm and the average daily flooding time is ≤2h; the low tide plant culture column is buried at a depth of 800mm and the average daily flooding time is ≥6h.

[0012] The diameter, arrangement angle, and number of the stay cables are determined based on the local maximum wind speed to ensure the stability of the system under level 10 winds.

[0020] Figure 2 for Figure 1 Top view. Detailed Implementation

[0021] See Figures 1-2 This utility model includes: a main greenhouse structure 1 and a lower mesh water passage 2, a cement column foundation 3, a greenhouse entrance 4, an inward-facing plexiglass roof 5, a storm surge stabilization device 6, a high tide beach plant cultivation column 9, a low tide beach plant cultivation column 10, and an automatic environmental monitoring device within the greenhouse. The main greenhouse structure 1 is connected to the cement column foundation 3 via a heated steel frame support. The mesh water passage 2 at the bottom of the main greenhouse structure 1 is connected to a fine nylon fishing net (mesh size ≤ 30mm) to prevent aquatic organisms from consuming the plants inside the greenhouse during high tide. The storm surge stabilization device 6 is connected to the cement column foundation 3 via a cable-stayed connection. The automatic environmental monitoring device within the greenhouse includes: light... The system includes a light-temperature monitor 7 and a water level-tide monitor 8; the light-temperature monitor 7 is connected to the top beam of the main greenhouse unit 1; the water level-tide monitor 8 is connected to the high tide tidal flat plant cultivation column 9 and the low tide tidal flat plant cultivation column 10, respectively, and is installed in the high tide simulated cultivation column 9 and the low tide simulated cultivation column 10 to precisely monitor water level differences; the upper part of the high tide tidal flat plant cultivation column 9 and the low tide tidal flat plant cultivation column 10 are provided with drainage holes 11 to prevent excessive flooding and ensure a uniform water level standard; the high tide tidal flat plant cultivation column 9 and the low tide tidal flat plant cultivation column 10 are connected to the main greenhouse unit 1 through steel frame supports, thereby ensuring the stability of the plant cultivation column under the influence of hydrodynamics.

[0022] The storm surge stabilization device 6 uses damping alloy connectors to fix the cable-stayed foundation to the concrete column. The cable diameter is Φ≥5mm, and the tension requirement is calculated based on the local maximum wind speed. It can generally withstand wind loads up to level 10. Galvanized steel wire is used to meet the high salinity and corrosion resistance requirements of seawater. Meanwhile, the concrete column foundation 2 must be at least 800mm deep underground to effectively prevent the greenhouse structure from tilting and the foundation from settling during storm surges.

[0023] The high tide beach plant cultivation column 9 and the low tide beach plant cultivation column 10 are PVC cultivation columns with adjustable diameter and height. Each column has a greenhouse gas static box matching slot 12 at the top, which can form a sealed space with the light and dark static boxes for greenhouse gas emission monitoring. The bottom of both columns is connected to a permeable bottom cover 13. The permeable bottom cover 13 has several holes with a diameter of Φ=10mm and is lined with 250-mesh nylon mesh to prevent soil loss while ensuring soil permeability. Furthermore, the cultivation columns can be adjusted in depth to simulate the sea-level rise crisis commonly faced by coastal tidal flats under the influence of global climate change. For example, the high tide beach plant cultivation column 9 simulates the high tide beach habitat environment, where the water passage time is short and the flooding depth is shallow under natural tidal action, while the low tide beach plant cultivation column 10 closely resembles the low tide beach habitat environment, where the water passage time is long and the flooding depth is deep under natural tidal action. The external greenhouse and internal plant cultivation column of the climate change simulation system can effectively simulate the combined effects of global warming and sea-level rise on coastal wetlands and monitor their impact on the stability of ecosystem functions.

[0024] To make the technical solution and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that the following embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0025] See Figures 1-2This utility model includes: a greenhouse main unit 1 and a lower mesh water passage 2, a cement column foundation 3, a greenhouse entrance 4, an inward-facing plexiglass roof 5, a storm surge stabilization device 6, a light-temperature monitor 7, a water level-tide monitor 8, high tide beach plant cultivation columns 9 and low tide beach plant cultivation columns 10. The cement column foundation 3 is made of high-strength concrete with a depth ≥800mm to ensure stability under the soft geological conditions of the tidal flat. A damping alloy connector is pre-embedded at the top of the cement column foundation 3, which is rigidly connected to the hot-dip galvanized steel plate support of the greenhouse main unit 1. This damping alloy connector has excellent corrosion resistance and elastic deformation. The system has the ability to absorb the vibration energy generated by storm surges, preventing the system from tilting. The storm surge stabilization device 6 consists of galvanized steel wire cables with a diameter of ≥5mm. The upper end of the cable is connected to the top beam of the main greenhouse unit 1, and the lower end is anchored to the cement column foundation 3. The diameter, arrangement angle, and number of the cables are calculated based on the local maximum wind speed to ensure the system's stability under level 10 winds. The mesh water passage 2 is set along the circumference of the greenhouse at the lower part of the main greenhouse unit 1, with a width of approximately 500mm. Based on the local tidal difference, it ensures smooth water flow during high and low tides, and the overall system's stability under high tide flooding conditions. The lower part is covered with a high-strength, fine-mesh nylon fishing net (mesh size ≤30mm). This nylon net uses corrosion-resistant synthetic fiber material and is connected to the passage frame via a detachable snap-fit ​​structure, ensuring natural water flow while effectively preventing fish, crabs, and other aquatic organisms from invading the greenhouse and consuming the plants. The nylon mesh can be disassembled and cleaned periodically to prevent algae from adhering and affecting permeability. The high tide tidal flat plant cultivation column 9 and the low tide tidal flat plant cultivation column 10 adopt a segmented design, and the column diameter can be adjusted according to the vegetation type (standard specifications are Φ100mm / Φ200mm / Φ300mm). The height of the soil covering area at the bottom of the cultivation column is adjustable (adjustment range 300-800mm). A drainage hole 11 (10mm diameter, 50mm height from the soil surface) is provided at the top to ensure a consistent water level in each cultivation column under flooded conditions. A permeable bottom cover 13 is connected to the bottom of the cultivation column, and the bottom cover has an array of Φ10mm permeable holes (hole spacing 20mm) lined with 250-mesh nylon mesh. This design perfectly simulates the permeability characteristics of tidal flat sediments while preventing soil erosion.By adjusting the burial depth of the cultivation column and flexibly adjusting it according to local tidal conditions, different tidal flat elevation environments can be accurately simulated. The burial depth of the high tide tidal flat plant cultivation column 9 is 400mm, with an average daily flooding time of ≤2h; the burial depth of the low tide tidal flat plant cultivation column 10 is 800mm, with an average daily flooding time of ≥6h; the light-temperature monitor 7 uses a multispectral sensor array, arranged one or a group along the greenhouse beams, to monitor PAR (photosynthetically active radiation) and temperature spatial distribution in real time; the water level-tide monitor 8 is a pressure sensor, vertically installed on the side column, with a measurement accuracy of ±1mm, and can record the complete hydrological process line of tidal rise and fall; a static box slot 12 is set at the top of the cultivation column; the static box slot 12 can be quickly docked with a transparent / shaded static box to form a sealed air chamber, and a laser gas analyzer (accuracy 0.1ppm) is used to continuously monitor CO2 / CH4 / N2O flux, and the data can be wirelessly transmitted to the central control system.

[0026] This utility model requires three levels of debugging after installation:

[0027] Structural stability test: Simulate a level 10 wind load (wind speed 28.5m / s) for 2 hours, and monitor the tilt of the main structure to be ≤1°;

[0028] Hydrological simulation verification: Compared with measured tidal data, the water level control error is ≤5%;

[0029] Ecological consistency verification: Through sediment particle size analysis and vegetation physiological index measurement, the ecological equivalence between the simulated environment and the natural tidal flats is ensured.

[0030] This invention breaks through the limitations of traditional designs and creatively solves the special engineering challenges of coastal tidal flat environments. The system forms a triple storm protection system through the rigid connection between the main greenhouse structure 1 and the cement column foundation 3, combined with the cable-stayed structure of the storm surge stabilization device 6. The cement column foundation 3 is set at least 800mm underground and uses galvanized steel wire cable-stayed structures (Φ≥5mm), capable of withstanding wind loads up to level 10. This design demonstrates excellent stability under storm surge conditions. The mesh-like water passage 2 at the bottom of the greenhouse, connected to a fine nylon fishing net, effectively prevents damage to the plants inside the greenhouse by aquatic organisms during high tide.

[0031] This invention's gas circulation system embodies the design concept of "ecological metabolism." The tops of the high tide and low tide plant cultivation columns 9 and 10 are equipped with greenhouse gas static chamber matching slots 12, which, together with the light and dark static chambers, form a sealed space, constructing a complete simulated ecosystem material cycle monitoring system. Through the synergistic interaction of microorganisms, plants, and the atmosphere at multiple interfaces, precise monitoring and dynamic balance control of greenhouse gas emissions are achieved. The coordinated operation of the light-temperature monitor 7 and the water level-tide monitor 8 provides accurate environmental parameter feedback for the gas circulation process.

[0032] This invention represents a qualitative leap in environmental control, moving from mechanical regulation to ecological simulation. The system utilizes adjustable-depth tidal flat plant cultivation columns 9 and 10, along with a permeable bottom cover 13, to accurately simulate coastal tidal flat habitats at different elevations. The permeable bottom cover 13 features 10mm pores lined with 250-mesh nylon mesh, preventing soil erosion while ensuring soil permeability. This design goes beyond simple water level control; it innovatively applies porous media and fluid dynamics to fully utilize and realistically reproduce the hydrodynamic characteristics of tidal rise and fall, including microscopic hydrological processes such as eddy formation and boundary layer effects. The tidal flat plant cultivation column 9 simulates the tidal flat habitat environment, while the tidal flat plant cultivation column 10 simulates the tidal flat habitat environment, comprehensively showcasing the gradient response of tidal flat vegetation to sea-level rise. The plant cultivation column and permeable bottom cover design not only achieve physical connection, but also promote the natural growth of roots and the organic integration of the substrate, perfectly simulating the ecological characteristics of natural tidal flats.

[0033] This invention innovatively combines external greenhouse environmental control with internal cultivation column water level regulation. Through intelligent monitoring of the main greenhouse device 1 and modular design of the cultivation column, it achieves precise simulation of the combined effects of global warming and sea-level rise on coastal wetlands. It can simultaneously monitor the combined impact of temperature increases and water level changes on the stability of ecosystem functions, providing a new technological platform for coastal wetland ecological research. Addressing the problem of interference from aquatic organisms such as fish on experimental vegetation in coastal tidal flat environments, this invention adds a high-strength, fine-mesh nylon fishing net to the mesh-like water passage 2 at the bottom of the main structure. This nylon net is made of corrosion-resistant synthetic fiber material, with precisely designed mesh sizes that ensure natural tidal flow while effectively blocking the intrusion of aquatic organisms such as fish and crabs, preventing them from grazing and damaging the plant roots inside the greenhouse. Simultaneously, the nylon net adopts a detachable installation structure, facilitating regular cleaning and maintenance, ensuring water permeability and protective effects over long-term use. This innovative design significantly improves the reliability of experimental data, providing important support for long-term simulation research of coastal wetland ecosystems.

[0034] The above embodiments have provided a detailed description of the present invention, but those skilled in the art can make various improvements without departing from the principles of the present invention. For example, replacing the nylon fishing net with a stainless steel filter screen, or integrating a root observation window into the culture column, etc., these modifications and improvements should all be included within the protection scope of the present invention.
