Recycling Study Of Influence On City Space Form Of Subsidence Area In Huaibei City

From the party’s eighteen big put forward the urbanization is an important task of the strategic adjustment of the economic structure and change the mode of economic development, to the central economic work conference and make further deployment, promote urbanization actively and steadily, and strive to improve the quality of urbanization. It can be said that China is now in an important stage of deepening reform, promote the development of the new urbanization, has been involved in the population space transfer, economic progress and social changes, cultural evolution and the change of system. A large number of city is experiencing a hitherto unknown, structural change, city spatial morphology as the urban and rural planning core areas of research and hot issues, will have a significant impact on the development and evolution.Coal resource type city is an important part of a special type of our country city and town system, the spatial form evolution process has a certain particularity. The coal resource type city, coal mining subsidence is a creature with coal mining inevitably, originally can be used as arable land or the development and use of land resources has become a wasteland, and even geological disasters, causing the city dispersed, complex boundary. In order to put this kind of land by the negative factors into the positive factors of the city, many coal resource type city of coal mining subsidence areas reclamation has conducted the research and the practice, but in this special transition period, from the space form the perspective of the coal mining subsidence area function is very few. This paper takes Huaibei city as an example, based on the platform of GIS data, by spatial analysis as the main method, the subsidence area in Huaibei city recycling effect on space form of empirical study, think the choice of "spatial form, multi center compact" should be the city of Huaibei, and from the reuse of angle to the spatial pattern of Huaibei City optimization of the recommendations put forward in subsidence area.Analysis on the time evolution of the city space development as the basis, the sector, circle ring and the office of the streets as the basic spatial unit, rate, extended from the city expansion direction, function and internal structure and many other aspects, for the reuse of subsidence area reclamation, analysis of the main construction land and waters, green two kinds of effects on city space the quantitative, establish collapse impact area space shape model, using correlation analysis of subsidence area change and spatial form, and summarize the characteristics of its influence. Finally, put forward Huaibei city space form of optimal mode selection, subsidence area in Huaibei city from the angle of space optimization proposals put forward.This thesis believes that the increase in the number of reclamation on urban space construction area plays an important impetus role; reclamation subsidence area, for the city outward expansion direction is less affected by the whole; subsidence area of land for housing in a certain range of their outward expansion of influential role; has a significant effect on urban internal industrial land layout out, this kind of influence decline in the proportion of public facilities; dispersion contribute a certain distribution effect is not very significant.The subsidence area reclamation of lakes and green to the Huaibei city building incremental intensity transfer to the East and south of the lake, the size of the water will directly affect the construction pace of growth. Increased lake green directly affects the city leisure center distribution, contact improves phase mountain and Lieshan District, Duji District space. As a result of the overall planning of the city will collapse area land reclamation for urban green heart, to optimize the pattern of urban space.By taking Fushun and Datong as an example, the objective law and combined with coal urban spatial agglomeration, obtains the choice "space morphology and multi center compact" should be the city of Huaibei, and put forward from the collapse zone reuse angle optimization of spatial form of Huaibei City: the subsidence area reclamation into construction land, to guide urban Xiangshan Lieshan group, Duji and scattered land, effective consolidation, unified planning, cultivate group center, improve the group function, timely coordination of city road network structure, through the group between the main road and the expressway, the subsidence area in group center RE development with economic growth as the goal, in group edge should be strictly controlled the development of timing; the subsidence area reclamation for green and lakes, as between groups separated and growth boundary, the formation of good urban landscape and ecological environment, according to the water body is divided into different leisure function, its development should strictly control the green heart line, specification development and construction activities, shall not be arbitrarily occupied for other purposes or for a large number of development and construction city.
