【摘要】 随着水环境对城市化格局约束作用的日益明显,如何在水资源与环境胁迫条件下,建设资源节约和环境友好的城市化格局已成为相关部门关注的焦点。本文把水环境胁迫作为研究条件,以其揭示环鄱阳湖区城市化格局空间分异,目的在于为该区湖域生态经济区建设和发展提供科学决策的依据。文章通过“湖泊效应”假设和Bass技术创新模型提出了湖泊影响城市经济区分异,并以环鄱阳湖区为例,利用ArcGIS的缓冲区分析方法、回归和专题地图法,将环鄱阳湖区划分为核心、边缘和外围三大影响区。在此基础上,通过统计和kennel方法,建立城市化格局的单指标和复合指标考察方法,对环鄱阳湖区人口、经济、生活、基础设施和综合城市化格局分异分别进行了分析,得到以下结论：①假设表明,在无其他地理要素影响时,从理论上看,城市经济受湖泊影响程度随城市和湖泊的距离的增大呈现出先增大后减小的趋势,存在圈层层次,由此得到环鄱阳湖区的三层层次；②环鄱阳湖区水环境胁迫下城镇分布的总体格局是环湖核心区城市分布较为密集,向边缘区和外围区逐渐稀疏：③随着与鄱阳湖水体距离的增大,三大区域的城市化水平分异总体上呈现出先增大后减小的趋势。更多还原

【Abstract】 Along with the restraint of the water environment to urbanization pattern is more and more obvious, how to construct the pattern of resource conservation and environmental friendly urbanization has become the focus of the related departments in the water resources and environmental stress condition. This paper takes the water environment stress as the study condition, for the purpose of revealing the urbanization pattern surrounding Poyang Lake and providing the basis for scientific decision of the ecological economic construction and development.The paper proposes lakes affect the city economic zone through "lake effect" hypothesis and the Bass technology innovation model,and takes surrounding Poyang Lake for an example, useing the method of ArcGIS buffer analysis, regression and thematic maps, dividing the whole area into core, edge and peripheral influence area. Then it analyses the urbanization pattern of population, economy, life, infrastructure and comprehensive according to the statistical and kennel method, a single index and composite index investigation method, and gets the following conclusions:①Hypothesis suggests that the degree of city economy influenced by lakes is increasing firstly and then increasing with the change of the distance from the city and lakes in no other geographical factors influence, which gets three layers surrounding Poyang Lake;②the general distribution pattern of towns is that the core is more intensive, the edge and peripheral are gradually sparse under water environment stress;③along with the increase of space from Poyang Lake, the urbanization level of the three regions shows increasing firstly, then decreasing.更多还原
