Human-land coordination represents urbanization and is a key component of urban modernization. In this study, the theory of system dynamics was introduced, in which a "production-living-ecological" complex system was used based on the human-land coordination concept. Moreover, the characteristics of system dynamics of causal cycle, dynamic and sustainable development, man-land synergy, integrity and openness, and self-organization and adaptability were analyzed by dividing it into three subsystems: urban production, urban living, and urban ecological subsystems. Here, causal feedback and system structure flow diagrams were designed using causal loop diagrams and system structure flow diagrams to evaluate the causal relationships between variables and quantitatively analyzing their interactions between variables and predicting the future development of variables. Changsha City, China was selected as the case study area, where we constructed system dynamics practice equation model was then constructed to determine the interaction between the subsystems. Our findings indicate that by the year 2035 in the future, the overall trend of factors influencing the function of the subsystems such as population, GDP and built-up area are positively correlated with an increasing trend, and there are interactions between. Furthermore, these factors interact with each other, and a mutual correlation was found among the production-living-ecological functions system, Therefore, this study provides a novel perspective and exploratory practice for the study of the synergistic coupling of ecological, production, and living functions of cities and evaluating high-quality development of cities. Thus, the coupling and coordination of urban production, living and ecological functions reflects the coupling and coordination of the "people-land" relationship, which is the key to high-quality urban development.
人类-土地协调代表着城市化，是城市现代化的关键组成部分。在本研究中，引入了系统动力学理论，该理论基于人类-土地协调概念，采用了“生产-生活-生态”复合系统。此外，通过将其划分为三个子系统：城市生产、城市生活和城市生态子系统，分析了系统动力学的因果循环、动态和可持续发展、人地协同、整体性和开放性、自组织和适应性等特征。在这里，使用因果回路图和系统结构图设计了因果反馈和系统结构图，以评估变量之间的因果关系，并对变量之间的相互作用进行定量分析，预测变量的未来发展。选择中国长沙市作为案例研究区，构建系统动力学实践方程模型，以确定子系统之间的相互作用。我们的研究结果表明，到 2035 年未来，人口、GDP 和建成区等影响子系统功能的因素的总体趋势与增长趋势呈正相关，并且存在相互作用。此外，这些因素相互作用，生产-生活-生态功能系统之间存在相互关联，因此，本研究为研究城市生态、生产和生活功能的协同耦合以及评估城市高质量发展提供了新的视角和探索性实践。因此，城市生产、生活和生态功能的耦合协调反映了“人地”关系的耦合协调，这是城市高质量发展的关键。
