Simulation is a basic method to analyze water resources system and provide information for decision-making. In this study, a framework is presented that describes the basic elements in a water resource system and a modelling technique integrating conceptual simulation and rule control. To formulate the process of the water cycle and water exploitation with a mathematical model, the water system is described based on adjustable relevant rules and respective parameters with experiences and pragmatic demands in the framework. The rule set describes the principles required to design conceptual networks and control the concrete processes of movement and conversion of different water flows. Combined with object-oriented programming, different calculation functional modules are classified based on the characteristics of water source layers, and the processes that occur in the networks are realised in the computation. The influence of the South-to-North Water Diversion project on the Haihe River basin is analysed by the rule-based object-oriented water resource allocation simulation model. According to the simulation results, groundwater extraction will be reduced by 6,181 million m3. The relationship between water source replacement and water layer exchange in the Haihe River basin is analysed, and the feasibility of the model is verified. Based on the rule-based model, the user requirements can be taken into account conveniently, and the rules are flexible to adjust with experiences and real conditions. This model can be used to simulate complex water resource systems.

基于规则的面向对象水资源分配系统仿真模型

模拟是分析水资源系统并为决策提供信息的基本方法。在这项研究中,提出了一个框架,该框架描述了水资源系统中的基本元素以及将概念模拟和规则控制相结合的建模技术。为了用数学模型来描述水循环和水的开采过程,基于可调整的相关规则和各个参数,并结合框架中的经验和实用要求,描述了水系统。该规则集描述了设计概念网络并控制不同水流的移动和转换的具体过程所需的原理。结合面向对象的编程,根据水源层的特征对不同的计算功能模块进行分类,计算中实现了网络中发生的过程。通过基于规则的面向对象的水资源分配模拟模型,分析了南水北调工程对海河流域的影响。根据模拟结果,地下水开采量将减少61.81亿平方米3。分析了海河流域水源置换与水层交换的关系,验证了该模型的可行性。在基于规则的模型的基础上,可以方便地考虑用户需求,并且可以根据经验和实际情况灵活调整规则。该模型可用于模拟复杂的水资源系统。
