本文提出了一种社会生态弹性评价方法，并试图明确考察城市化对城市生态系统弹性的影响，以期探讨如何加强城市生态系统弹性的社会生态治理。运用灰色-模糊综合评价模型，以中国东部大都市区苏西长城市群为例，社会生态弹性总分总体呈上升趋势，从2001年的0.548分上升到2013年的0.760分。在同一时期，与环境质量恶化、污染排放、景观和生态治理变化有关的复原力增加，但与社会经济发展有关的复原力下降。此外，指标对其相关恢复力的贡献不同，揭示了不同扰动下恢复力的异质性。此外，还提出了几种情景，试图检测社会生态复原力与城市化之间的关系，目的是改善城市治理。结果表明，在僵化和垂直组织的治理形式下的快速城市化将导致社会生态系统失去弹性，甚至使其濒临崩溃。当城市用地扩张速度达到16%时，城市化带来的干扰会将社会生态系统推向特定的门槛，使其功能发生变化。然而，研究发现，适应性和协作性治理结合了公众参与和环境管理效率的提高，将加强具有韧性的社会生态治理，为城市系统提供广阔的运行空间，甚至加速城市化比率。
This article presents a social-ecological resilience assessment and attempts to explicitly examine the impacts of urbanization on resilience, with a view to explore how to strengthen social-ecological governance of the resilience of urban ecosystems. We use a combined Grey-Fuzzy evaluation model to discuss a case study of the Su-Xi-Chang city cluster, a metropolitan area in East China, in which total social-ecological resilience scores generally exhibited an upward trend, from 0.548 in 2001 to 0.760 in 2013. In the same period, resilience increased in relation to deterioration of environmental quality, pollution discharge, and landscape and ecological governance change, but decreased in relation to social-economic development. Besides, different contributions of indicators to their related resilience values reveal the heterogeneity of the resilience in terms of various disturbances. In addition, several scenarios are posited in an attempt to detect the relationship between social-ecological resilience and urbanization with the goal of improving urban governance. The results suggested that rapid urbanization under rigid and vertically organized forms of governance would cause the social-ecological system to lose resilience, or even to bring it near collapse. When the growth rate of urban land expansion reaches 16%, disturbances caused by urbanization would push the social-ecological system over a particular threshold, where the way it functions changes. However, it is found that adaptive and collaborative governance, incorporating increases in both public participation and the efficiency of environment administration, would strengthen social-ecological governance of resilience to provide the urban system with a wide operating space, and even with accelerated urbanization ratios.
