摘　　要：我国城市空间快速增长引发了日益加剧的区域生态风险,对实现可持续城市化构成严峻挑战。尽管从城市自身尺度的环境影响控制迈向区域整体范围的生态风险防御,已成为规划调控变革的内在需求。但建筑学等单一学科探索,难以有效应对城市—区域之间跨尺度、多要素的生态复杂性议题。通过国际经验检讨,从人地耦合系统的复杂性视角出发,立足于理论基础模型构建、区域生态风险辨识和规划方案绩效评估等3个基本模块,提出一种遵循"城市空间增长态势—资源环境压力变化—生态系统风险辨识—规划方案绩效评估"逻辑的方法模型,旨在改善城市规划实践中的区域生态风险防御能力。Abstract： Rapid spatial growth of China＇s metropolitans results in increasing hazard of regional eco-systems, which means austere challenge to sustainable urbanization in China. The transition of urban planning system is important to focus not only on environmental effect control inside cities, but also on ecological hazard defense of outside regions. However, the current research of traditional disciplines cannot deal with ecological complex of cross-scale and multi-factor between cities and their outside regions. After critical reviewing of international concerned experience, from CHANS perspective, the article proposes a methodological framework that includes building theoretical model, identifying regional ecological hazard, accessing plan＇s ecological performance; and that implies a logic connection from urban spatial growth statement, resource-environmental impact, and ecosystem hazard to ecological performance of plan. It will improve the capacity of urban planning system to defense regional ecological hazard in China＇s metropolitans.
