Abstract

Deforestation exerts profound ramifications on soil quality and biodiversity, thereby exerting substantial economic repercussions. The depletion of organic matter and structural integrity of soil following tree removal for agricultural purposes underscores the severity of this issue. In elucidating the soil pollution stemming from deforestation, this research employs a sophisticated five-compartment SDIFR model integrating fractal dimension and fractional order dynamics. The rigorous analysis, including the application of Picard Lindelof's fixed point theorem, establishes the existence and uniqueness of explicit solutions. Furthermore, the examination of local and global stability sheds light on the system's behavior, delineating between pollution-free equilibrium and pollution-extinct equilibrium states. To regulate system behavior, an adaptive control framework grounded in fractal fractional order is proposed, leveraging the Adams-Bashforth numerical approximation scheme for implementation. Through numerical simulations, the study underscores the pivotal role of parameters, thus substantiating the significance of the proposed model in comprehensively addressing the complexities of soil pollution induced by deforestation.

摘要

森林砍伐对土壤质量和生物多样性产生深远影响,从而产生重大的经济影响。为了农业目的而砍伐树木后,土壤有机质的消耗和结构完整性的破坏凸显了这个问题的严重性。在阐明森林砍伐造成的土壤污染时,本研究采用了一个复杂的五室SDIFR模型,该模型整合了分形维数和分数阶动力学。包括应用皮卡德·林德洛夫不动点定理在内的严格分析,确定了显式解的存在性和唯一性。此外,对局部和全局稳定性的研究揭示了系统的行为,区分了无污染平衡和污染灭绝平衡状态。为了调节系统行为,提出了一个基于分形分数阶的自适应控制框架,并利用亚当斯-巴什福斯数值近似方案进行实施。通过数值模拟,该研究强调了参数的关键作用,从而证实了所提出模型在全面解决森林砍伐引起的土壤污染复杂性方面的重要性。
