AI Technical Summary

Technical Problem

Existing aquatic ecosystem assessment models struggle to balance computational efficiency with ecological realism. Mechanism models have numerous parameters that are difficult to calibrate, habitat suitability models lack dynamic process explanations and descriptions of interspecific interactions, and statistical learning models lack explanations of biological mechanisms.

Method used

A model based on the coupling mechanism of aquatic habitat is adopted, including an input layer, a configuration layer, a simulation layer and an output layer. The differential evolution algorithm is used to optimize environmental factors and ecological processes. Combined with hydrodynamic module, habitat module and interspecific competition ecological module, key ecological processes are integrated through selective mechanism coupling to output the ecosystem distribution results.

Benefits of technology

It achieves high-efficiency computing while maintaining ecological realism, improves computing efficiency by two orders of magnitude, and the parameters have clear ecological significance, supporting rapid scenario analysis and real-time decision-making.

Abstract

The present application relates to the technical field of ecological environment, in particular to a water ecological system evaluation system and method based on a water habitat coupling mechanism model. The technical problem is to integrate key ecological mechanisms while maintaining high computational efficiency. The system includes: an input layer that receives measured data related to the water environment of the target water habitat; a configuration layer that selects several indicators from the geographic indicators, hydrological indicators, hydrodynamic indicators and meteorological indicators input by the input layer, and configures multiple different environmental factors; key ecological processes are integrated through selective mechanism coupling, and interspecific competition factors are configured for algae and biological interaction factors are configured for fish; the simulation layer uses a differential evolution algorithm to automatically calibrate and optimize the parameters configured by the configuration layer; obtain the spatial and temporal changes of aquatic plants, algae and fish; the output layer outputs the spatial distribution results of the three species of aquatic plants, algae and fish, and provides suggestions for scenario analysis results and environmental economic balance decision-making.
