Abstract

The application provides a method and device for predicting changes in ecosystem stability based on interference scenario simulation, and relates to the technical field of ecological environment assessment and ecological restoration. The method comprises the following steps: constructing a species-habitat network and dividing the functional groups of the species; determining a habitat node deletion sequence; simulating the process of step-by-step deletion of habitat types in the species-habitat network according to the habitat node deletion sequence, calculating the robustness index and the functional stability index; further determining the comprehensive stability index and the stability threshold water level; realizing the transition from static assessment to dynamic process simulation, quantifying the cumulative loss trajectory of species and function in the interference process; constructing a more comprehensive ecosystem stability evaluation index by comprehensively considering the network structure robustness and the functional group stability; and automatically identifying the stability threshold water level based on the curve inflection point, providing an objective, systematic and quantitative basis for ecological water level control and restoration decision-making.
