摘　　要：以国家战略地区鄱阳湖生态经济区为研究区域,将建成区面积作为城市规模的测度指标,确定了城市规模与经济绩效的耦合匹配分析模型,并以规模—经济匹配值的时空差异分析作为切入点,研究城市规模与经济绩效的耦合情况。研究表明:鄱阳湖生态经济区城市规模的增长逐年加快,尤其是在2010-2012年期间,交通干线经过地区的城市规模有了明显扩张;从2001年到2012年,城市规模与经济绩效偏离理想状态较多的地区明显减少,耦合情况的区域差异有所缩小,且每个时段均存在规模主导区域多于经济主导区域的情况;城市规模与经济绩效耦合程度的改善在2001-2005年和2010-2012年这两个时间段最为明显,并且规模主导区域的面积呈向西部递减的趋势。This essay takes Poyang Lake Eco -economic Region as the research area, using SPSS to analyze typical indexes about urban size and economy achievement. After building up a model to research the coupling degree between urban size and economy achievement, this essay conducts the analyzing process according to the coupling degree changing in temporal and regional dynamic. The result shows that： the expanding speed of the proportion of built - up region is increasing year by year, especially from 2010 to 2012, and the region which traffic lines pass by is spreading significantly; from 2001 to 2012, the region which deviated from ideal state has markedly been re- duced, and the regional difference has narrowed. Also, there are more size - dominating regions than economy - dominating ones; the coupling degree between urban land and economy achievement has greatly improved from 2001 to 2005 and from 2010 to 2012, and the proportion of size - dominating regions tends to as the tendency to decrease westwards.
