The high-speed economic growth of mega city-regions in China has been characterized by rapid urbanization accompanied by a series of environmental issues ranging from widespread soil contamination to groundwater depletion. This article begins with an analysis of the interaction between urbanization and the ecological system and reviews existing frameworks for analyzing urban and ecological systems. By taking the Beijing-Tianjin-Hebei region as an example, the article introduces a conceptual framework to analyze mega city-regions and forecast possible interactions between urbanization and eco-environment by applying simulation model. The proposed framework and its components can provide guidance to identify the impacts of urbanization and external forces such as globalization on eco-environment by integrating the internal and external factors, synthesize the complex components of mega city-regions in databases, understand and diagnose the casual relationship between urban policies and ecological consequences.
中国特大城市地区的高速经济增长的特点是快速城市化，伴随着一系列环境问题，从广泛的土壤污染到地下水枯竭。本文首先分析了城市化与生态系统的相互作用，并回顾了现有的分析城市和生态系统的框架。本文以京津冀地区为例，引入了一个分析特大城市地区的概念框架，并通过应用模拟模型来预测城市化和生态环境之间可能的相互作用。所提出的框架及其组成部分可以通过整合内部和外部因素，在数据库中综合特大城市地区的复杂组成部分，理解和诊断城市政策与生态后果之间的因果关系，为识别城市化和全球化等外部力量对生态环境的影响提供指导。
