Study On The Change Of The Urban Layout Of The Main Urban Area In Jinan City In Recent Ten Years

China has entered a stage of stable development of urbanization. After the level of urbanization reached 45%, the urban population dominated from small cities to large cities. In 2009, the level of urbanization in China has reached 45.68%, entered a golden period for development of major cities. The rapid expansion of urban land and land size of the frequent adjustment of the layout become an important socio-economic development performance. However, the current examination of evolution for the layout of urban land yet to be improved and deepened. Based on the traditional research methods of urban planning, this paper learns spatial analysis methods of geography to construct analysis methods of the evolution of urban layout, selects the main city of Jinan over the past decade as the research object, in-depth analysis on layout evolution of the whole and the function of urban land and growth of land use.Research shows that over the past decade the main mode of the overall expansion of urban land in Jinan was filled circle, evolved into "strip" from "Point+ surface", underwent the process from the period of rapid growth experienced land to the gentle process. Orientation expansion mode changed from the significant axial expansion to slow "becoming round" extension. Over the past decade, land east of the main city was the major expansion wing, the north and west wing was the secondary expansion. Most land use growth centers concentrated in outside the central city areas, especially the east of main city.The expansion mode of main function sites were "concentric circles+axis" oriented, and the trend of expansion to the east were very significant. The most prominent of residential land extended was in the land increase capacity, the strength of expand and other. They were major force of Jinan main urban expansion for the past decade. Growth transfer of three types of main functional land was different. The specific performance was that the residential land gathered inward, industrial land migrated and dispersed and the public service area gathered steadily eastward.Based on the detailed analysis of the evolution of urban land use distribution of Jinan main city in the last decade, we superposed the three editions of land layout diagram from 1996 to 2007 and the land layout long-term diagram of Jinan City Overall Plan (2006-2020), thus intuitively compared the consistency of urban land use layout and evolution of main function land use with the overall plan over the past decade. The results showed that the evolution of layout of the total urban land, industrial land and public service area was consistent with the layout plan of the overall plan, but the overall space and public facilities sites were loose, land intensity was not high, industrial land required further relocation and integration. The evolution of layout of the living space and planning intention of the relocation type is still quite different.Although the morphology of Jinan City shows as a "band tour" mode, urban land locates outside of the circle, especially the unceasingly expansion of eastern new town, resulting in the irrationality of the main city evolution mainly oriented the "concentric circle filling" development increasingly significantly. The residential areas concentrate to the central city while the industrial and public service facilities migrate to the outside, leading to the not uniform of land distribution evolution, thus results in the space mismatch for living and employment and other a range of issues. In this regard, our paper proposes the following two control measures:transformation from the "single center" cohesive city to the "multi-center" network city and responds positively to a new round of planning guidance to promote the orderly development of city.
