[0001] The present invention relates to the technical field of ecosystem health assessment, and more particularly to a multifunctional freshwater ecosystem assessment method and system. Background Art

[0002] At present, freshwater is one of the main natural resources for human survival, and ensuring freshwater security is a common goal of mankind. However, due to the growing population, pollution of rivers, lakes and watersheds, groundwater depletion, and intensified droughts and floods caused by climate change, freshwater ecosystems and the services they provide have been degraded. Therefore, the concept of assessing the natural and ecological status of various freshwater ecosystems has emerged.

[0003] However, although the existing freshwater ecosystem evaluation process requires consideration of multiple indicators, it does not take into account the ecology and species conditions of freshwater ecosystems. In addition, the division of assessment results is mostly based on fixed thresholds, without considering the specificity of each different freshwater ecosystem.

[0004] Therefore, how to provide a freshwater ecosystem assessment method that can solve the above problems is an issue that technicians in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a multifunctional freshwater ecosystem assessment method and system, which can more accurately assess the health status of freshwater ecosystems by acquiring water quality data, ecological environment data, and human activity data and constructing a model based on the above data.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0009] Constructing a freshwater health risk assessment model, and classifying the water quality data, the ecological environment data, and the human activity data according to the freshwater health assessment model to obtain freshwater health positive indicators and freshwater health negative indicators;

[0010] A freshwater health evaluation index calculation model is constructed, and the freshwater health positive index and the freshwater health negative index are pre-processed and input into the freshwater health evaluation index calculation model for calculation to obtain corresponding evaluation results.

[0011] Preferably, it also includes:

[0012] Processing the freshwater health positive indicator and the freshwater health negative indicator to determine a plurality of actual threshold results;

[0013] The assessment results are divided according to the multiple actual threshold results to determine the health of the freshwater ecosystem.

[0014] Preferably, the specific process of determining multiple actual threshold results includes:

[0015] Extracting features of the freshwater health positive indicator and the freshwater health negative indicator respectively to obtain corresponding positive features and negative features;

[0016] Combining the positive features and the negative features to obtain corresponding comprehensive features;

[0017] An analysis model is constructed, and the comprehensive features are input into the analysis model for processing to obtain multiple threshold results.

[0018] Preferably, the specific process of constructing a freshwater health risk assessment model includes:

[0019] Constructing a corresponding ecological network module according to the ecological environment data;

[0020] Constructing an ecological knowledge graph model based on the water quality data, the ecological environment data, and the human activity data;

[0021] The ecological network module and the ecological knowledge graph model are integrated to obtain a corresponding freshwater health risk assessment model.

[0022] Preferably, the specific process of constructing the corresponding ecological network module includes:

[0023] Extracting biological logical relationships from the ecological environment data;

[0024] The biological logical relationship is mined and analyzed to obtain the corresponding ecological network module.

[0025] Preferably, the specific process of obtaining the corresponding evaluation result also includes:

[0026] Determine a corresponding biological integrity index and a biodiversity index according to the ecological network module and the ecological data;

[0027] The assessment result, the biological integrity index and the biodiversity index are weighted and fused to obtain a final assessment result.

[0029] The acquisition module is used to obtain water quality data, ecological environment data and human activity data of freshwater ecosystems;

[0030] A construction module is used to construct a freshwater health risk assessment model, and classify the water quality data, the ecological environment data and the human activity data according to the freshwater health assessment model to obtain freshwater health positive indicators and freshwater health negative indicators;

[0031] A calculation module is used to construct a freshwater health evaluation index calculation model, and pre-process the freshwater health positive index and the freshwater health negative index and input them into the freshwater health evaluation index calculation model for calculation to obtain corresponding evaluation results;

[0032] The classification module is used to classify the evaluation results according to the multiple actual threshold results to determine the health level of the freshwater ecosystem.

[0033] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a multifunctional freshwater ecosystem assessment method and system, which has the following beneficial effects:

[0034] First, water quality data, ecological environment data, and human activity data of freshwater ecosystems are obtained. By constructing a freshwater health risk assessment model, the obtained data is classified to obtain freshwater health positive indicators and freshwater health negative indicators. The freshwater health positive indicators and negative indicators are processed to determine multiple actual threshold results. The assessment results are divided according to these thresholds to determine the health of the freshwater ecosystem. This step increases the flexibility and accuracy of the assessment. When constructing a freshwater health risk assessment model, the method also involves constructing an ecological network module and an ecological knowledge graph model. The above data covers multiple aspects of the ecosystem, and the biological integrity index and biodiversity index are integrated into the assessment results. The integration of the above processes helps to have a deeper understanding of the structure and function of the ecosystem and provide stronger support for the assessment.
