Description

Technical Field

[0001] This invention relates to the field of ecological and environmental research, specifically to a method and system for identifying the influencing factors of ecological damage events on the structure and function of ecosystems. Background Technology

[0002] With the deepening of ecological civilization construction, the scientific identification and accountability of ecological and environmental damage incidents have received increasing attention. Accurately identifying the influencing factors of ecological damage incidents on the structure and function of ecosystems is a key prerequisite for carrying out ecological and environmental damage assessment, liability determination, and restoration and governance. Currently, relevant technologies mainly rely on remote sensing monitoring, field investigations, water / soil physicochemical analysis, biological community surveys, and multi-source data fusion modeling to conduct preliminary screening and correlation analysis of potential influencing factors (such as pollutant emissions, hydrological disturbances, habitat destruction, etc.). However, existing influencing factor identification methods generally have a key deficiency: the lack of a systematic verification mechanism to verify whether the identified influencing factors actually cause damage to the structure and function of the ecosystem, especially the lack of causal verification methods based on process simulation or scenario inversion. This leads to a high false positive rate in influencing factor identification, large attribution uncertainty, and weak remediation targeting, which in turn affects the fairness of ecological and environmental damage compensation and the effectiveness of ecological restoration projects. Summary of the Invention

[0003] The purpose of this invention is to provide a method and system for identifying the influencing factors of ecological damage events on the structure and function of ecosystems. This solves the problem that existing methods lack a systematic verification mechanism to determine whether the identified influencing factors actually cause damage to the structure and function of ecosystems.

[0004] This invention achieves the above objective through the following technical solution: a system for identifying the impact factors of ecological damage events on ecosystem structure and function, used in aquatic ecosystems, comprising: The environmental information acquisition module is used to collect water quality and species information of aquatic ecosystems; The monitoring module is used to collect image information about the aquatic ecosystem. The processing module is used to receive and process the information collected by the environmental information collection module, determine whether the structure and function of the aquatic ecosystem have been damaged, and detect the information collected by the monitoring module when the structure and function of the aquatic ecosystem are damaged, and identify the ecological damage event that has caused damage to the structure and function of the aquatic ecosystem. The identification module is used to identify influencing factors based on the ecological damage events obtained by the processing module; The verification module verifies whether the influencing factors damage the structure and function of the aquatic ecosystem. An alarm module is used to issue an alert when the structure and function of the aquatic ecosystem are damaged; The verification module includes a base, a rotating frame mounted on the base, several trays mounted on the rotating frame, a lifting component mounted on the base, a simulation box mounted on the moving end of the lifting component, and an environmental control device mounted on the simulation box.

[0005] Preferably, the tray has a rotating shaft on both sides, and the rotating shaft is rotatably connected to the rotating frame.

[0006] Preferably, the outer wall of the rotating shaft is provided with a mounting ring, the rotating frame is provided with a driving component, the moving end of the driving component is provided with a limiting component, the limiting component is provided with a detection component, and the driving component is used to drive the limiting component to move and contact the mounting ring when the detection component detects that the tray is tilted, so as to limit the rotation of the tray.

[0007] Preferably, the limiting member includes an annular support block and a collar rotatably disposed on the annular support block, the annular support block being disposed on the moving end of the driving member, and a counterweight being disposed at the bottom of the collar.

[0008] Preferably, the annular support block and the collar are both fitted onto the outer wall of the rotating shaft, and the inner diameter of the annular support block and the collar are both larger than the outer diameter of the rotating shaft.

[0009] Preferably, the collar has an elastic pad on the side facing the mounting ring, and the mounting ring has a protrusion on the side facing the collar.

[0010] Preferably, the detection component includes a detector disposed on the counterweight and a detection block disposed at the bottom of the mounting ring.

[0011] Preferably, the counterweight is equipped with a vibrating element.

[0012] Preferably, a method for identifying the influencing factors of ecological damage events on ecosystem structure and function, utilizing the aforementioned system for identifying the influencing factors of ecological damage events on ecosystem structure and function, includes the following steps: S1: The environmental information acquisition module collects water quality and species information of the aquatic ecosystem in real time, and the monitoring module collects image information of the aquatic ecosystem in real time. The information collected by both is transmitted to the processing module. S2: The processing module processes and analyzes the information collected by the environmental information collection module to determine whether the structure and function of the aquatic ecosystem have been damaged. When the structure and function of the aquatic ecosystem are damaged, the monitoring module detects the information collected by the monitoring module to determine the ecological damage event that has caused damage to the structure and function of the aquatic ecosystem. The alarm module issues an alarm when the structure and function of the aquatic ecosystem are damaged. S3: The identification module identifies the influencing factors based on the ecological damage events obtained by the processing module; S4: The lifting mechanism drives the simulation box to move down and cover it above a tray. The environment inside the simulation box is controlled by the environmental control equipment to simulate the aquatic ecology. This is used to verify whether the influencing factor has damaged the structure and function of the aquatic ecosystem. If no error is found, it is confirmed that the influencing factor has damaged the structure and function of the aquatic ecosystem.

[0013] The beneficial effects of this invention are as follows: By setting up a verification module, a digital or process-based simulation environment with high similarity to the actual damaged aquatic ecosystem is constructed. Potential influencing factors (such as specific pollutant concentrations, sudden reductions in flow, and intensity of sediment disturbance) output by the identification module are quantitatively applied to the simulated ecological environment as input variables, and the response process of the aquatic ecosystem to its structure and function is dynamically simulated. By comparing the simulation results with the actual observed ecological damage status (such as species loss and functional degradation indicators), it is possible to scientifically determine whether the identified influencing factors have the ability to cause similar damage, thereby realizing the mechanism verification and quantitative confirmation of the causal relationship of the influencing factors. This verification process effectively overcomes the false positive attribution problem caused by traditional methods that rely solely on statistical correlation or empirical inference, and significantly improves the accuracy of influencing factor identification.

Detailed Implementation

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1

[0018] Please see Figure 1 An identification system for the impact factors of ecological damage events on ecosystem structure and function is proposed for use in aquatic ecological environments. The system includes: an environmental information acquisition module, a monitoring module, a processing module, an identification module, a verification module, and an alarm module. The environmental information acquisition module collects water quality information (water temperature, pH, dissolved oxygen, conductivity, turbidity, nutrients, organic pollution, toxic pollution (pesticides, heavy metals), hydrological and hydrodynamic parameters (flow rate, velocity, water depth, water level fluctuations, etc.; these parameters are obtained through detection sensors, which are existing technologies and will not be described in detail here) and species information (phytoplankton, zooplankton, benthic animals, aquatic vascular plants, fish, microorganisms, etc.). The monitoring module refers to monitoring equipment installed around the aquatic ecological environment, and the processing module refers to a remote platform (such as a computer). Please refer to Figure 2 and Figure 3 The verification module includes a base 1, on which a rotating frame 2 is rotatably mounted. Multiple trays 3 (which are open boxes) are evenly arranged on the rotating frame 2. The trays 3 are equipped with simulated aquatic ecological environments. A lifting component 4 (such as an electric telescopic rod) is provided on the side wall of the base 1. A simulation box 5 is provided on the moving end of the lifting component 4. The bottom of the simulation box 5 is open. An environmental control device 6 is provided on the simulation box 5. The environmental control device 6 includes temperature and humidity control devices and other devices that change the external environment of the aquatic area.

[0019] It should be noted that a motor is installed on the rotating frame 2, which is used to drive the rotating frame 2 to rotate different trays 3 directly under the simulation box 5, so as to quickly change the simulation environment.

[0020] A method for identifying the influencing factors of ecological damage events on ecosystem structure and function, the specific steps of which are as follows: First: The environmental information acquisition module collects water quality and species information of the aquatic ecosystem in real time, and the monitoring module collects image information of the aquatic ecosystem in real time. The information collected by both is transmitted to the processing module. Second: The processing module processes and analyzes the information collected by the environmental information collection module to determine whether the structure and function of the aquatic ecosystem have been damaged (by comparing the detected data with the set thresholds; if there is a difference between the compared data and the difference is greater than the normal fluctuation range, it is judged as abnormal; otherwise, it is normal). When parameters are abnormal, the ecological damage event is inferred based on the abnormal parameters (the time of the abnormality is inferred based on the abnormal parameters, such as the large-scale disappearance of submerged plants (Vallisneria natans, Potamogeton crispus), the complete absence of sensitive groups of benthic animals (mayflies, stoneflies), with only the pollution-tolerant species Tremella fusiforme remaining, and the chlorophyll a concentration in the water reaching as high as 80 μg / L). The normal concentration is <10 μg / L), and the transparency is only 0.3 m. A high concentration of triethyltin chloride (TETR, a component of marine antifouling paint) of 120 μg / kg was detected in the surface sediment. Based on the above parameter changes, it is preliminarily inferred that there is illegal discharge of sewage from a ship or leakage from a sunken ship. When the parameters are abnormal, the processing module detects the information collected by the monitoring module to determine the ecological damage event that has damaged the structure and function of the aquatic ecosystem (the specific time of ecological damage is confirmed by the monitoring information. When it is consistent with the inferred ecological damage event, the ecological event is confirmed as the time that caused the ecological damage). At the same time, the alarm module issues an alarm. Third: The identification module identifies influencing factors based on the ecological damage events obtained from the processing module. (For example, when the ecosystem is damaged due to illegal discharge of sewage from ships or leakage from sunken ships, it is necessary to further screen out the specific influencing factors (i.e., damaging factors) that actually cause damage to the ecosystem in the event. These factors may be a specific pollutant, physical disturbance, or a combination thereof. Specifically, this involves comprehensively collecting environmental samples from emission sources and recipients (including emission source samples (e.g., residual liquid at the leakage point, wastewater from the discharge outlet, and residues in the accident storage tank), recipient environmental samples (e.g., polluted water, surface sediment, soil, and biological tissues (fish, shellfish)), and control samples (e.g., unaffected water, soil, and organisms in the upstream / background area)), screening and quantitative analysis of all pollutant components (non-targeted / broad-spectrum screening; targeted quantitative analysis), preliminary screening based on toxicity and concentration, chemical fingerprinting and source tracing verification (e.g., using isotope fingerprinting technology), and determining the influencing factors). It should be noted that influencing factors are specific components or physicochemical properties of emitted / leaked substances that are toxic, inhibitory, or destructive to the structure or function of the ecosystem. Examples include: chemical factors such as aniline, hexavalent chromium, petroleum hydrocarbons (TPH), and ammonia nitrogen; physical factors such as high-temperature wastewater, high-turbidity sludge, and strong acids / alkalis; and biological factors such as pathogenic microorganisms. Fourth: Rotating frame 2 rotates, moving tray 3 containing the simulated aquatic ecosystem directly below simulation box 5. Lifting component 4 drives simulation box 5 to move down and cover the tray 3. Environmental control device 6 controls the environment inside simulation box 5 to simulate aquatic ecosystem. Then, it is verified whether the influencing factor has damaged the structure and function of the aquatic ecosystem (the influencing factor is applied to tray 3, and then the changes in the simulated aquatic ecosystem are detected. If the changes are the same as the damaged ecological environment in the outside world, then the influencing factor is a factor that damages the ecological environment; otherwise, it is not. Here, the influencing factor refers to the above parameters, such as aniline, high-temperature wastewater, etc.). After verification, it is confirmed that the influencing factor has damaged the structure and function of the aquatic ecosystem.

[0021] It should be noted that the lifting component 4 drives the simulation box 5 to move upward, so that the simulation box 5 is removed from above the tray 3. The rotating frame 2 is rotated so that the other trays 3 correspond to the simulation box 5. Then the lifting component 4 drives the simulation box 5 to move downward to cover the tray 3, thereby realizing the replacement of the simulation environment.

[0022] In this embodiment, as a further optimization, please refer to... Figure 3 The left and right side walls of the tray 3 are equipped with rotating shafts 301, and the two rotating shafts 301 are rotatably connected to the rotating frame 2. When the rotating frame 2 rotates to adjust the position of the tray 3, the rotating shafts 301 rotate on the rotating frame 2 to ensure that the tray 3 is in a horizontal state, so as to avoid the tray 3 being unable to rotate with the rotating frame 2 and reduce the probability of the tray 3 tilting and tipping over.

[0023] Example 2

[0024] As a further optimization of Example 1, please refer to Figure 3 , Figure 4 and Figure 5 An installation ring 8 is fixedly sleeved on the outer wall of the rotating shaft 301. A driving component 7 (such as an electric telescopic rod) is provided on the rotating frame 2. A limiting component 9 is provided on the moving end of the driving component 7. A detection component is provided on the limiting component 9. The detection component is used to detect whether the tray 3 is tilted. When it is detected that it is tilted, the external control device (such as PLC control) controls the driving component 7 to work, so that it drives the limiting component 9 to move and contact the installation ring 8, so that the rotating shaft 301 cannot rotate, thereby fixing the tray 3 and preventing it from tipping over and causing the objects inside the tray 3 to fall out.

[0025] It should be noted that when the external control device is connected to the alarm, it will also control the alarm to sound an alarm when it drives the drive unit 7 to work, so as to alert the staff.

[0026] In this embodiment, as a further optimization, please refer to... Figure 4 and Figure 5The limiting component 9 includes an annular support block 901 and a collar 902 rotatably mounted on the annular support block 901. The annular support block 901 is located on the moving end of the driving component 7. A counterweight 12 (a metal part, such as an iron block) is provided at the bottom of the collar 902. The detection component includes a detector 14 (infrared rangefinder) located on the side wall of the counterweight 12 and a detection block 10 (a metal block) located at the bottom of the mounting ring 8. The detector 14 and the detection block 10 are aligned. During the rotation of the rotating frame 2, the detection block 10 always faces downward. Since the annular support block 901 and the collar 902 are rotatably connected, the counterweight 12 also always faces downward. At this time, the detector 14 detects the distance between itself and the detection block 10. This distance is a safe distance (the safe distance is a preset number, and the driving component 7 does not work at this time). If the tray 3 is tilted, it will cause the detection block 10 and the detector 14 to be misaligned, and the distance measured by the detector 14 will increase. After receiving this information, the external control device controls the driving component 7 to start.

[0027] In this embodiment, as a further optimization, please refer to... Figure 4 and Figure 5 Both the annular support block 901 and the collar 902 are fitted on the outer wall of the rotating shaft 301. The inner diameter of the annular support block 901 and the collar 902 is larger than the outer diameter of the rotating shaft 301, so that the annular support block 901 and the collar 902 do not contact the outer wall of the rotating shaft 301, ensuring that the annular support block 901 and the collar 902 are not disturbed by the rotating shaft 301, and ensuring that the counterweight 12 always faces downward.

[0028] In this embodiment, as a further optimization, please refer to... Figure 5 The collar 902 has an elastic pad 903 (rubber material) on the side facing the mounting ring 8, and the mounting ring 8 has a protrusion 11 on the side facing the collar 902. When the collar 902 is pushed by the driving component 7, the elastic pad 903 contacts the protrusion 11, increasing the friction between the collar 902 and the mounting ring 8, which is used to prevent the mounting ring 8 from rotating with the rotating shaft 301, so that the tray 3 is fixed more stably.

[0029] In this embodiment, as a further optimization, please refer to... Figure 5 The counterweight 12 is equipped with a vibrating element 13 (such as a vibration motor); the vibrating element 13 works to make the collar 902 vibrate, ensuring that the counterweight 12 always faces downward.

[0030] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
