本文应用系统动力学原理，就太平沟小流域资源的开发利用进行了系统分析，绘制了ＳＤ模型流程图，编制了ＳＤ模型程序，经微机模拟仿真，确定了“综合型”发展为该流域资源开发利用方向，为该类型区小而域经济建设及两高一优农业发展提供了科学依据和方法。 This paper systematically analyzes the development and utilization of resources in Taipinggou watershed by using the principle of system dynamics, and draws the flow chart of SD model and compiles the SD model program. Through computer simulation, it determines that the development of “integrated type” Development and utilization of the direction for the type of small and medium-sized area of ​​economic construction and two high and one excellent agricultural development provides a scientific basis and method.
