Subregion Research Of Urban And Rural Construction Sites Linked To Potential In Zhuzhou City

China’s land resources are abundant, but the obvious contradiction between the people and land. Mainly for a large population, low per capita arable land, arable land reserve resources; Second, with the process of urbanization, rapid economic growth trend of building occupation of agricultural land increases, especially the occupation of cultivated land. Land resources are non-renewable resources, the material conditions necessary for human survival and coordination of land use, economic, social, ecological relationship between the three, to improve their efficiency, to go the route of sustainable development, society as a whole needs major reality. Zhuzhou City, Hunan Province, the old industrial city and commercial center, transportation hub,"City Group" in key areas, on the one hand, accelerated the Zhuzhou city’s rapid economic growth, while the radiation effects on the surrounding areas; will inevitably lead to urban construction land occupation of cultivated land, increasing demand and shortage of arable land contradictions intensified. How in the case of a limited supply of land resources, coordination of arable land and urban development, has become an important concern of the government and many researchers. The number of new urban construction land in the planning is difficult to meet the circumstances of urbanization and economic development, and tap the urban and rural construction sites linked to the potential basis for the potential partition is particularly important to explore all levels of hook run. According to domestic and international urban sprawl, finishing rural settlements, urban and rural construction land increase or decrease linked to the research and theoretical basis, a regional overview of Zhuzhou City, rural residential land consolidation potential, linked to demand for urban construction land, urban and rural construction sites linked to potential, urban and rural construction land linked to changes in the partition, the urban and rural construction sites linked to the implementation of countermeasures analysis, paper core as follows:Chapter Ⅳ, according to the2001-2010Zhuzhou City land use status quo annual change survey and the2002-2011Zhuzhou City Statistical Yearbook data, choose one:urban construction land, rural residential land, mining land, transportation, water conservation land, other construction land, GDP, the secondary industry, tertiary industry, investment in fixed assets, the population size class10data, constitute the model output and input indicators. Programming software using Matalb2010, C2R and DMU model is invalid in the DEA model to improve the various construction sites, urban counties2001-2010; all types of construction sites will be improved, the use of RBFNN estimates the urban counties2008-2010, all types of construction estimated value of land and the relative error, confirmed the authenticity of the RBFNN in computing; RBFNN in the sim () function estimates the size of the various types of land for construction of urban counties in2020; estimated that after2020, urban construction land, rural residential land in the scale of urban construction land in2010, the difference of the size of the rural residential land, with the planning of urban construction land, comparison of the incremental control indicators of rural residential land, urban land for construction of the urban counties linked to demand and rural residential land consolidation potential; based on the difference between the above estimates the counties and urban and rural construction land linked to changes in potential, Zhuzhou City, the total potential of519.97hectares.Chapter V, linked to changes in urban counties and rural construction land potential, Zhuzhou City is divided into three urban and rural construction land linked to changes in area, are as follows: first-grade integrate region, two-grade integrate region, three-grade integrate region, corresponding to propose suitable for all levels of district, urban and rural construction sites linked to the run plan. Linked to changes in the implementation of urban and rural construction land, district at all levels were as follows:the integration of urban and rural areas, the village system of integrated planning, market-oriented, off-site linked; shrink and scattered villages, the construction of the village center, the entire village to move out a strange land, a combination of government-the market; control within the village land, local adjustment, the government-led type.
