From NPFW to OAB: Ecosystem Impacts and Organic Agriculture Feasibility Study Based on Lotka-Volterra

In this study, we constructed a natural process food web (NPFW) model based on the Lotka-Volterra model and the Logistic growth model, and quantitatively analyzed the role of natural factors on the ecosystem by setting the period function to simulate the agricultural cycle, while introducing the relevant influence coefficients to assess the impact of the ecological purification algorithm on the stability of the ecosystem. On this basis, the human-decision food web (HDFW) model was constructed, and the regulation parameter of the ecological purification algorithm was set to zero to simulate the impact of the ecological purification algorithm deactivation on the ecosystem, and two variables, namely, the intelligent predation module and the ecological pollination module, were introduced to analyze the impact on the ecosystem. Finally, the organic agriculture benefit (OAB) model was constructed, and the hierarchical analysis method (AHP) was applied to quantitatively evaluate different organic agriculture methods. This study provides a systematic solution for ecosystem research and organic agriculture development through the quantitative analysis of multiple models.
