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. |
