摘要
基于系统动力学建模方法分析了循环农业动态评价问题,建立了循环农业模式的系统动力学动态评价模型。根据系统思考理论,将评价指标放入一个循环农业模式系统中进行分析,基于流程再造理论设计丘陵地区的循环农业流程,以此为据建立其SD仿真模型,分析该循环农业模式的合理性。根据丘陵地区循环农业SD模型中稻谷产量、总收入和污染量3个主要变量的分析结果,运行循环农业系统动力学动态评价模型,仿真得到评价结果,进而表明构建的丘陵地区循环农业流程合理可行,且运用系统动力学方法动态评价循环农业科学有效。
Based on system dynamics,the dynamic evaluation pommels of circular agriculture were analyzed.The system dynamic estimation model of circular agriculture model was established.All the evaluation indices were put into a circular agriculture model system according to the system thought theory.The circular agriculture flow of upland was designed based on flow reconstruction theory.On this basis,SD simulation model was set up and the rationality of the circular agriculture model was analyzed.According to the analysis results of three main variables（paddy yield,total income and pollutant amount） in SD model,the dynamic estimation model of circular agriculture system was run.And the evaluation results were obtained.The research showed that the circular agriculture mode of upland was reasonable and feasible.And the estimation of circular agriculture with system dynamic estimation model was scientific and effective.
