Study On The Evolution Of Spatial Structure Of Energy-resource Type Urban

This article takes the research object by the North Shaanxi Energy ChemicalIndustry Base' s key urban------Yulin, which is alao a emerging energy-resource typeurban.First, carries on the limit of scope to the present domestic resource type urbans. In this foundation, carries the analysis on the spatial structure type and the characteristic and the existing questions of the resource type urbans. Then, taking the resource type urbans as a whole research object and relating the urban spatial structure to the urban function type, summaries the spatial structure evolution rule of the resource type urbans from the development angle. And further, inspects spatial structure evolutionary process of two typical time's resource type urbans, carries on the ponder to the emerging resource type urban' s spatial structure development, and proposes one kind of possible spatial development pattern of the emerging resource type urbans which is Chain Type Spatial Structure.And then, carries on the analysis to the present urban developing characteristic of Yulin, points out that Yulin now belongs to the emerging energy-resource type urban. According to the leading resource which the resource type urban depends on, Yulin belongs to the coal-resource type urban. At the same time, looking from the environment that Yulin locates, it belongs to the model of the frail ecological environment area. Then, drawing on the experience of space proliferation rule of resource type urban, carries on the delimit of the regionalizing development scope of Yulin in advance when its resource industry develops to mature stable time.Furthermore, using for reference of the development and construction experienceand lesson of the resource type urbans of early time, points out that the research of urban space development strategy of future is necessary and important for Yulino At the same time, unifying to the research frame of space development strategy of resource type urbans, points out that the characteristic of this article lies in that it differents from taking the industrial development plan as the outset basis of the research as ordinary, but takes the Chain Type Space Development Pattern of the emerging resource type urbans which is proposed by the author in front asjhe logical beginning of the research o And under the instruction of the Chain Type Space Developing Pattern, carries the consideration on the urban space developmental strategy of Yulin from three region stratification plane?In this foundation, drawing on the experience of the spatial structure evolution rule of the resource type urban, points out that the spatial structure development of Yulin will also inevitably display gradual characteristic along with the unceasing evolution of the urban function type <> Then, combining the research of development stage division of the coal-resource type urban, approximately forecasts the urban function evolution stage of Yulino Further, points out that its urban spatial structure approximately will experience three development phases in the entire process of Yulin's resource industry developing to mature period, and points out the corresponding relation between the spatial structure development pattern and the urban function type at each stage oFinally, carries on the summary on the main conclusion of this article and points out the insufficiency which exists and awaits improvement °...
