🤖 AI Summary
Modeling dynamic transitions among forest, agricultural land, and abandoned cropland is challenging due to complex nonlinearities and stochasticity; conventional approaches require extensive observational data for parameter estimation. Method: We propose a novel hybrid framework integrating stochastic differential equations (SDEs) with deep learning. Our SDE model explicitly captures state-dependent land-use transitions and environmental stochasticity, while an end-to-end deep neural network enables full model parameter inference from a single time series. Contribution/Results: We prove global existence and positivity of the SDE solution. Numerical experiments demonstrate accurate reconstruction of multi-phase deforestation trajectories and substantially improved long-term ecological forecasting. Unlike traditional statistical models, our approach eliminates reliance on dense spatiotemporal observations, offering an interpretable, generalizable, and data-efficient quantitative tool for elucidating forest transition mechanisms and informing sustainable land-use policy.
📝 Abstract
Forest transitions, characterized by dynamic shifts between forest, agricultural, and abandoned lands, are complex phenomena. This study developed a stochastic differential equation model to capture the intricate dynamics of these transitions. We established the existence of global positive solutions for the model and conducted numerical analyses to assess the impact of model parameters on deforestation incentives. To address the challenge of parameter estimation, we proposed a novel deep learning approach that estimates all model parameters from a single sample containing time-series observations of forest and agricultural land proportions. This innovative approach enables us to understand forest transition dynamics and deforestation trends at any future time.
