Abstract: China is in an accelerating urbanization stage, city circle is an inevitable and higher stage. Poyang lake city circle, as the new representative in the central China, provides a good example for this study. Symbiosis theory is cooperation and coordination in essence, consistent with development concept of city circle. This paper uses symbiosis theory to analyze situation of Poyang lake city circle, and establishes an evaluation system which consists of 21 indexes in four sub-systems, economy, society, resource and environment, and scores the 8 cities inside Poyang lake circle by means of factor analysis, and finds out there are issues existing in Poyang lake city circle, such as uneven development, small radiation range, poor overall planning, and regional difference on sustainable development awareness, and presents suggestions on pushing the sustainable development of Poyang lake city circle. 

Key words: Poyang lake city circle, symbiosis theory, factor analysis, sustainable development 

摘要： 我国正处于城市化加速发展阶段，而城市圈是我国城市化发展的必经阶段，也是更高级的阶段。作为中部地区较有代表性的新兴城市圈——鄱阳湖城市圈的发展具有较强的研究意义。共生理论的本质是合作与协调，这与城市圈的发展理念是相吻合的。文章从共生理论的视角出发，首先对鄱阳湖城市圈共生现状进行了特征分析。然后，结合当前理论基础与鄱阳湖城市圈的实际情况构建了包含经济、社会、资源和环境4个子系统，21项指标的综合测度评价体系，并运用因子分析法计算出鄱阳湖城市圈所含的8个城市在各主成分上的得分以及综合得分。研究发现鄱阳湖城市圈存在发展不平衡、辐射范围小、规划整体性低、可持续发展意识地区差异大等问题。最后针对这些问题，从6个方面提出建议以推动鄱阳湖城市圈的可持续发展。
