Agricultural Sustainability Analysis Based on Ecological Modeling: Species Restoration, Chemical Reduction, and Ecosystem Balance

Conventional agriculture poses environmental challenges, necessitating species restoration and reduced chemical inputs for sustainability. This paper develops models to analyze four key aspects: (1) native species re-emergence, (2) herbicide discontinuation, (3) the role of bats in ecosystem balance, and (4) the transition to organic farming. The Ecological Synergy Growth Model (ESGM) simulates species interactions, showing that within 12 months, plant populations recover to 40% of environmental carrying capacity, and insect populations stabilize at 300. The Herbicide Impact Dynamics Model (HIDM) reveals that weed populations surge after herbicide removal but stabilize by the 6th month, with a 15% crop yield reduction and a 10% increase in species richness. The Bat Ecological Function Model (BEFM) demonstrates that bats reduce pests by 35% and boost crop yields by 25%. The Organic Transition Benefit Model (OTBM) indicates that while organic farming initially reduces profits by 20%, long-term benefits include a 30% price premium, surpassing conventional farming after five years. These models provide insights for sustainable agriculture by balancing ecological and economic factors. Sensitivity analysis validates the models, with future improvements focusing on dynamic herbicide strategies and climate adaptation.
