本文描述了一个基于能值的城市动态模型的发展，该模型能够准确地模拟观测到的北京的资源消耗、经济增长和环境影响。该模型与以往的城市能量模型不同，它监测了发展中城市系统对人类福祉和生态系统完整性的负面影响。一种新的观点侧重于将这种影响与供给侧环境成本评估（包括生态服务供应、生态和经济损失以及治理投资）联系起来的城市综合绩效。在这篇介绍性论文中，我们提出了基于能值的城市动态模型中最重要组成部分的概念考虑：城市资产、土地、资本、人口、水资源、经济和环境损失。该模型中的每个子系统都将丰富反馈动态、策略杠杆和场景后分析。在这种动态能量计算中还考虑了统计信息和校准。本研究通过整合上游和下游评估方法，通过解决对人类健康和生态系统完整性的具体损害，并将这些影响与供应侧环境成本评估联系起来，推进了能量会计的时间动态原则，以量化环境影响。
This paper describes the development of a forecasting model, named the emergy-based urban dynamic model capable of accurately simulating the observed resource consumption, economic growth and environmental impact of Beijing. This model differs from previous urban emergy models by monitoring the negative effects to human well-being and ecosystem integrity in the developing urban system. A fresh perspective focuses on urban comprehensive performance linking such impacts to a supply-side environmental cost evaluation (including ecological service supply, ecological and economic losses and investment for treatment). In this introductory paper, we present the conceptual considerations of the most important components of the emergy-based urban dynamic model: the urban assets, lands, capitals, population, water resources, economic and environmental loss. Each subsystem in this model will enrich the feedback dynamics, policy levers and post-scenario analyses. Statistical Information and calibration are also considered in this dynamic emergy accounting. This study advances the temporal dynamic principles of emergy accounting through integrating upstream and downstream evaluation methods to quantify the environmental impact by addressing specific damages to human health and ecosystem's integrity and by linking such impacts to a supply-side environmental cost evaluation.
