济南都市圈城市化空间分异特征及其引导策略

随着快速城市化的发展,都市圈成为我国大城市功能地域组织的重要形式。本文对济南都市圈城市化发展的空间分异特征和问题进行了分析,发现济南都市圈中虽然济南具有较高的集聚规模,但却缺乏相应的辐射带动能力,圈内多数县域尤其是黄河以北地区城市化滞后,加之其它中心城市实力不够强大,严重阻碍了济南及其都市圈竞争优势的发挥。由此提出了"强化核心、多元中心、区域联动、县域支撑"的城市化空间布局策略,并以城乡土地资源合理利用为核心,分别就土地分类管制和分区引导等两方面城市化协调引导机制进行了探讨。

SPATIAL DIFFERENTIATION FEATURES AND DEVELOPING STRATEGIES OF URBANIZATION IN JINAN METROPOLITAN REGION

In the movement of rapid urbanization,the metropolitan region becomes an important form of metropolis functional area concept in China.This paper analyses the spatial differentiation features and problems of urbanization in Jinan metropolitan region utilizing the data of the Fifth Census,and concludes that although Jinan has a large population of city agglomeration,lacking the ability of radiating and driving the other circumjacent cities or towns to develop is still a problem.On one hand,most of counties in the metropolitan region especially those lie to the north of the Yellow River hold a low degree of urbanization.On the other hand,the other central cities around Jinan do not have enough competitive power to develop more smoothly.All these problems limit the competitive strength of Jinan city and the region.The other features could be summarized as follows.First,the whole urbanized level of Jinan metropolitan region was close to that of Shandong province,but there was big disparity in the same region.Second,the urbanization of Jinan and the metropolitan region was mostly driven by the inner agglomeration of central cities,but the development of middle-small towns contributed more to those areas around the Jinan city.Third,the density of population was very high in Jinan metropolitan region,but the density of urban population was much lower comparatively.The spatial distribution of population was relatively balanced in Jinan metropolitan region,and the degree of convergency was not prominent.Fourth,industrialization accelerated the urbanization process of Jinan metropolitan region,but urbanization did not have obvious effect of increase of scale to the industrialization process.There was inconsistency between urban and industrial development in some counties.Last,immigration of population showed the same rule of gross production distribution. Considering the problems and trends,the author raises the urbanization spatial developing strategy of "Intensify the Core,Multiply the Center,Interregional Linkage,and County Underlay".
