【摘要】 在实地调查、资料搜集和系统分析的基础上，以典型坨沼地区甘旗卡镇的草地农业系统为例运用系统动力学方法建立了坨沼地区草地农业系统综合开发利用的系统动态仿真模型，并仿真试验了不同经营策略下未来十年系统行为与动态。通过对试验结果的多目标分析，从中优选出三套可供同类地区参考的经营模式，其中草地农业型模式是这类地区发展持续、高效农业的理想模式。更多还原

【Abstract】 This study developed a system dynamic model whichsimulated the grassland farming system in sandy hill and sandy land areas. By using the model in the typical area, Ganqika Town,the dynamics of its grassland farming system development on different conditions of management decision were simulated. And three models were selected, which were commodity grain model,combining farming and animal husbandry model and grassland farming model. Among them, the latter was optimum model.更多还原
