Description

Technical Field

[0001] This invention belongs to the field of ecological environment monitoring and assessment technology, and in particular relates to a method and system for assessing the stability of wetland ecosystems. Background Technology

[0002] As one of the world's three major natural ecosystems, wetlands play an important ecological role in regulating runoff, purifying water quality, maintaining biodiversity, and regulating microclimate. The stability of wetland ecosystems is directly related to regional ecological security and sustainable development. The stability of wetland ecosystems is affected by multiple factors such as hydrology, soil, meteorology, and biology. It is necessary to collect, analyze, and evaluate data from multiple dimensions to accurately grasp their stability and trends.

[0003] Existing wetland ecosystem stability assessment systems mostly rely on manual sampling and offline analysis, resulting in low monitoring efficiency and data lag. Furthermore, they lack specialized protective designs for wetland environments characterized by high humidity, abundant humus, and easy corrosion, making equipment prone to damage and data loss. This necessitates data collection again, thereby reducing the assessment efficiency of the wetland ecosystem stability assessment system.

[0004] To address these issues, we propose a method for assessing the stability of wetland ecosystems and a systematic approach. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of poor data acquisition efficiency and easy damage of detection probes in the prior art, and to propose a method and system for assessing the stability of wetland ecosystems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A method and system for assessing the stability of a wetland ecosystem includes a wetland ecosystem stability assessment system, which comprises a data acquisition module, a data transmission module, a data processing and assessment module, and an early warning module. The data acquisition module is connected to the data processing and assessment module via the data transmission module, and the data transmission module is connected to the early warning module via the data processing and assessment module. The data acquisition module includes a fixed-point acquisition unit and a mobile acquisition unit. The fixed-point acquisition unit includes a mounting bracket, a multi-parameter sensor group, and a data acquisition device. The mounting bracket is made of hot-dip galvanized metal, with an anti-settlement base at the bottom and a waterproof mounting box at the top. The multi-parameter sensor group includes a water quality sensor, a soil sensor, a meteorological sensor, and a biological sensor. All sensor probes are equipped with anti-corrosion coatings and protective nets. The data acquisition device has a built-in storage module, supports multiple protocol compatibility, can receive data from each sensor in real time and perform preliminary preprocessing, and also has a local data backup function to prevent data loss due to network interruption. The mobile data acquisition unit includes a drone and a portable monitoring terminal. The drone is equipped with a remote sensing sensor and a high-definition camera. The remote sensing sensor uses multispectral imaging technology to collect ecological pattern indicators such as wetland area, natural shoreline ratio, and riparian ecological land ratio over a wide area. The high-definition camera is used to patrol wetland vegetation destruction and illegal sewage discharge ecological stress behaviors. The portable monitoring terminal can manually collect supplementary data for local wetland areas and can interact with the fixed-point data acquisition unit.

[0007] Preferably, the data transmission module includes a wireless transmission unit and a wired transmission unit. The wireless transmission unit includes a LoRa module and a 4G / 5G module. The LoRa module is used for short-range transmission of real-time data from the fixed-point acquisition unit, adapting to the signal transmission requirements of complex wetland terrain. The 4G / 5G module is used for long-range transmission of all acquired data to the data processing and evaluation module, supporting rapid transmission of large amounts of data.

[0008] Preferably, the wired transmission unit is used for a stable connection between the data processing and evaluation module and the early warning module to avoid early warning delays caused by wireless signal interference.

[0009] Preferably, the data processing and evaluation module includes a data calibration unit, an indicator weight calculation unit, a stability evaluation unit, and a data storage unit. The data calibration unit is used to remove outliers and correct errors in the collected multi-dimensional data, and to calibrate the data in combination with the characteristics of the wetland environment to improve data accuracy.

[0010] Preferably, the indicator weight calculation unit adopts the analytic hierarchy process (AHP) and, in combination with the ecological characteristics of different types of wetlands, assigns weights to hydrological, soil, meteorological, biological, and ecological pattern assessment indicators. Specifically, marsh wetlands are assigned weights primarily for wetland area and biodiversity indicators, lake wetlands are assigned weights primarily for water resources and water system connectivity indicators, and coastal wetlands are assigned weights primarily for climate change-related indicators.

[0011] Preferably, the stability assessment unit has a built-in improved ecological stability assessment model, which calculates the comprehensive index of wetland ecosystem stability by combining calibrated data and indicator weights. The data storage unit uses a combination of cloud storage and local storage to store collected data, calibration data, assessment results and historical data, and supports data query, export and traceability.

[0012] Preferably, the early warning module includes a graded early warning unit and an early warning output unit. The graded early warning unit sets four levels of early warning according to the stability assessment results, corresponding to four stability levels. The early warning output unit includes an audible and visual alarm, an SMS push module, and a display terminal. The audible and visual alarm is installed at the wetland management station. The SMS push module is used to push early warning information to management personnel. The display terminal is used to display monitoring data, assessment results, and early warning status in real time, supporting management personnel to keep abreast of the wetland's ecological stability.

[0013] A method for assessing the stability of a wetland ecosystem includes the following steps: Step 1: When using this wetland ecosystem stability assessment system, the system includes a data acquisition module, a data transmission module, a data processing and assessment module, and an early warning module. These modules facilitate the assessment of wetland ecosystem stability. The system uses fixed-point and mobile acquisition units to form a structure that allows for both fixed-point and mobile data collection. This enables comprehensive data collection from multiple perspectives, reducing manual sampling and automatically analyzing the data. Step 2: The wireless and wired transmission units of the data transmission module are used to facilitate stable transmission of data collected over long and short distances. The data calibration unit, index weight calculation unit, stability assessment unit, and data storage unit of the data processing and evaluation module are used to calibrate the data. The index weight calculation unit uses the analytic hierarchy process (AHP) to assign weights to the collected data. The stability assessment unit uses an improved ecological stability assessment model to calculate the comprehensive index of wetland ecosystem stability by combining the calibrated data and index weights. The data storage unit stores the data. Step 3: Finally, the hierarchical early warning unit and early warning output unit of the early warning module are used to facilitate the setting of four-level early warnings corresponding to the four stability levels. The audible and visual alarm, SMS push module and display terminal of the early warning output unit can provide real-time early warning reminders for abnormal situations, thereby improving the assessment efficiency of the wetland ecosystem stability assessment system.

[0014] In summary, the technical effects and advantages of this invention are as follows: By setting up data acquisition, data transmission, data processing and evaluation, and early warning modules for a wetland ecosystem stability assessment system, the system facilitates the assessment of wetland ecosystem stability. The data acquisition module utilizes fixed-point and mobile acquisition units to form a structure for both fixed-point and mobile data collection, enabling comprehensive, multi-directional data acquisition of the wetland ecosystem. This reduces manual sampling and allows for automated data analysis. The fixed-point acquisition unit employs mounting brackets, multi-parameter sensor arrays, and data loggers, with anti-corrosion coatings and protective nets on the sensor probes to mitigate the impact of the wetland's high humidity, abundant humus, and corrosive environment. The mobile acquisition unit utilizes drones and portable monitoring terminals to achieve large-scale, comprehensive monitoring and precise supplementary monitoring in specific areas. This addresses the limitations of existing technologies in terms of single monitoring indicators and limited scope, comprehensively reflecting the overall state of the wetland ecosystem and improving the assessment efficiency of the wetland ecosystem stability assessment system.
