Study On Spatial Structure Of Chang-Zhu-Tan Urban Agglomeration Based On The Concept Of Compact City

Compact city concept in many western countries have been widely recognized as a sustainable city concept, initially as a city development strategy in the Netherlands, soon extended to many countries in Europe. The core idea is to compact the city's spatial structure, focus on the layout of the model, reducing people's dependence on private cars and promote public transport and walking. It is mainly directed against the endless expansion of the city, as a proposed urban development strategy, and also avoid a large number of loss of cultivated land, resources, uncontrolled waste and the spread of suburbanization.With the two types of society into full swing, gives Changzhutan City Group building a new meaning, its core idea is trying to break through resource and environmental constraints, and achieve the production, consumption and other economic activities and the coordination of natural ecosystems. Introduction of the concept of two types of social functions for both the government and intensive land use, industrial distribution, ecological compensation and restriction, or expansion of the City Group size, function optimization, structural coordination, quality improvement, environmental improvement and so forth have made new challenges.In this paper, from compact city concept, based on the current situation analyzing the spatial structure of Changzhutan Urban Agglomeration, build a compact spatial structure of Changzhutan urban agglomeration degree evaluation index system of fuzzy evaluation method by its spatial structure of the compact, we found that the City Cluster spatial structure of form layout is not close enough, a large regional differences in population distribution, compact low levels, land use is not intensive, extensive and even waste and also more common in secondary industry is too high, industrial awaiting adjustment, private car ownership continued to rise, public transport-oriented transport network has not yet formed, overall still in the low compact stage.Therefore, from the Compact City view, Changzhutan City Group spatial structure should be optimized several aspects:spatial distribution of urban agglomeration on the implementation of multi-center, functional groups, and decentralized centralized model; to improve the degree of population distribution of compact; handle non-construction land construction land and the relationship between control of construction land increment; coordinated development of urban agglomerations and industrial relations, accelerating the pace of development of tertiary industry; to improve the road system within the city to actively develop inter-city rail traffic, restrictions on private cars use, build green public transport corridor. In order to achieve a reasonable population density of Changzhutan urban agglomeration, balanced the rational distribution of population structure. Improving land use efficiency, measure up a high degree of spatial concentration of industrial transformation, to build the appropriate a compact space structure forms.
