中文摘要：

促进经济与环境协调是煤炭城市可持续发展的关键和核心。采用物质流分析、脱钩分析和分解分析等方法,深入分析了1995—2007年徐州市经济增长与资源环境之间的脱钩类型、可持续状态及驱动因素。结果表明：研究期内徐州市DMI和DPO的年均增长率分别为2.74%和0.91%,而GDP年均增长率为12.62%,二者之间呈较为明显的正相关关系,而物质代谢效率的提升又使其发展方式呈现向资源节约型、环境友好型发展模式转型的趋势;资源投入、废物排放与经济增长之间均出现弱脱钩现象,表明徐州经济系统正处于显著的弱可持续发展态势;经济规模扩大和技术效应抑制作用减弱是引起煤炭城市资源环境约束性增强、可持续发展降低的主要驱动因素。

英文摘要：

The integrated development of economy and environment is a key issue in the coal city.Based on the economic and environmental data selected from 1995 to 2007 of Xuzhou City,this paper analyzed the types of decoupling,the status of development and its driving factors between economic growth and resources environment using material flow analysis,decoupling analysis models and decomposition model.The results showed that the average annual growth rate of DMI and DPO is 2.74% and 0.91% respectively,while the average annual growth rate of GDP is 12.62%.The both present an obvious positive correlation.Moreover,the improvement of material metabolism efficiency can drive economy to a resource-saving and environment-friendly development model.Secondly,both resources input and waste emissions have the weak decoupling phenomenon with economic growth,which indicates an obvious weak sustainability of economic development in Xuzhou City.Thirdly,both the enlarging of additional economic scale and the weakening of inhibited effect of technology are the main driving factors to strengthen the constraint power of resource and environmental in the coal city.Lastly,for the past few years,the sustainability of the economic systems in the coal city has been reduced as the weakening of inhibited effect of technology.
