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 invention relates to the technical field of ecological environment, in particular to an aquatic ecosystem evaluation system and method based on an aquatic habitat coupling mechanism model. The technical problem is that a key ecological mechanism can be fused while high calculation efficiency is maintained. The system comprises an input layer for receiving measured data related to a water environment of a target aquatic habitat; the configuration layer screens a plurality of indexes from geographic indexes, hydrological indexes, hydrodynamic indexes and meteorological indexes input by the input layer, and configures a plurality of different environmental factors; key ecological processes are coupled and integrated through a selective mechanism, interspecific competition factors are configured for algae, and biological interaction factors are configured for fishes; the simulation layer uses a differential evolution algorithm to automatically calibrate parameters configured by the optimization configuration layer; the aquatic plants, the algae and the fishes are spatially and spatially changed; and the output layer is used for outputting spatial distribution results of three species, namely aquatic plants, algae and fishes, and providing suggestions and assistance for scene analysis results and environmental economy balance decisions.
