Abstract: To enhance the technical system for treating groundwater overextraction, four subsystems of the groundwater irrigation intake system, namely the water source system, intake system, water use system, and management system, are established by applying the principle of system dynamics. Through the analysis of the independent functions of the subsystems and their interactions, it is elucidated that the environmental conditions supporting the forward operation of each subsystem will transform into constraint conditions when the operation of each subsystem leads to the abnormal running of other systems. After the prompt feedback of the information system, the management department is required to adopt technical measures to manage and control the potential hazards during normal operation, ensuring that the environmental conditions and constraints of each subsystem remain within a reasonable range, thereby guaranteeing the normal operation of the entire system.

摘要： 为完善地下水超采治理技术体系,利用系统动力学原理,构建地下水灌溉取水系统的地下水水源子系统、动力取水子系统、灌溉用水子系统和管理子系统,通过分析子系统独立功能及其相互作用,阐述了各子系统正常运行的环境条件及其变化造成其他子系统异常时,支持其运行的环境条件就会变成约束条件。经过管理子系统及时反馈信息,管理部门需要采取技术措施控制正常运行中的潜在危害,使各子系统的环境条件和约束条件保持在合理范围,以保证整个系统正常运行。
