环鄱阳湖区城市化格局的空间分异分析

建立了城市化格局的单指标和复合指标测度体系,运用主成分分析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的空间分异进行了分析。研究发现:1)人口和基础设施城市化率呈现环湖边缘区最大,核心区其次,外围区最小的倒U形式的规律;经济城市化率则呈现边缘区最高,外围区次之,核心区最低的规律;而生活城市化水平呈现核心区最高,边缘区其次,外围区最低的格局。2)随着距鄱阳湖体距离的增加,城市化复合水平呈现依次下降的规律。该结果表明鄱阳湖作为一个特殊地理事物,它的存在对该区城市经济发展的空间分异具有一定程度的影响。

Spatial Variation of Urbanization in Area around Poyang Lake

A single indicator model and a comprehensive indicator model were established to study the urbanization pattern. The population, economy, lifestyle, infrastructure and comprehensive urbanization pattern in the area around Poyang Lake were analyzed with the principal component analysis method. The following conclusions were put forward in this paper ： 1 ） The population and the infrastructure urbanization rate showed a regular pattern that those of marginal zone was the highest, and the peripheral zone was the lowest. Obviously, center zone＇s was between the two zones. The economic urbanization rate showed a regular pattern that the marginal zone was the highest, and the peripheral zone was the second one, and the core area was the lowest one. However, the lifestyle urbanization and the marginal zone was between the two regions, expressed a trend that the core area was the highest one of three regions, and the peripheral region was the lowest one. 2 ） The level of urbanization for the three regions showed a trend that it reduced in return with the increasing of the distance from Poyang Lake. The result showed that as a special geographical thing, Poyang Lake with its water environment had a certain degree of influence on the space differentiation of the urban economic development.
