Study On Urban Land Intensive Use Potential Evaluation In Liaocheng City

With the accelerated process, and urban development on the demand for land is increasing.Our country has a large population of fewer conditions we decided to intensive land use, multisectoral increasingly aware of the intensive use of urban land importance.Town intensive land use and potential use of intensive research study not only for the development of land-use theory useful,but some of the city land-use practices have guiding significance.Urban land is urban social and economic development,and its level of use of the Town will bring different economic, social and environmental benefits.At present,China's land resources are becoming increasingly strained, and the majority of the cities intensive land-use low level, causing the waste of land and benefits. In order to raise the city's intensive land use, and realize sustainable urban land use, In this paper, learn at home and abroad advanced theory, research and practical methods on the basis of the investigation, using geographic information system as a major technical support to Liaocheng City as an example,In theory and practice of urban intensive evaluation of the potential use of the attempt made to explore.On theoretical aspect, the domestic and international research status quo and existent problem about urban land use have been discussed. The connotation and concept of urban land intensive use are given. Then the factors that affect urban land use have been analysed. After summarizing evaluating indexes and standards systematically and combining the actual condition of Liaocheng city, we make simple discuss on the present situation, potential size and intensive use tendency of urban land in districts of Liaocheng city.On practice aspect,the status quo of urban land intensive use in Liaocheng city has been evaluated for the first time.The potential of area,economic benefits and land asset in low degree use areas are also calculated. A vague method has been adopted when dividing function districts. In this way, evaluation is the first step.The second step is to divide function districts which are residential commercial, industrial and other function districts.The third step is to adjust confines. The evaluation is mainly about former three districts.A series of evaluating indexes are filtered using expert consulted method and statistical analysis method. Evaluating standards are also established according to national standards and actual conditions of Liaocheng city as well as domestic and international cities which are on equal developmental level.Every index has different weight.Four potential levels which are low, proper, intensive and exorbitant use areas are achieved with regional mark and limit methods. After comparing setted anticipant volume rate with current one, the two volume rates are pushed into the derived formula then the potential of low used districts is calculated.The economic benefit potential can be calculated combining merchandise room price and land asset potential in the same progress with standard Iand price. This model is used in calculation of commercial and industrial potential. Statistical frequency graphs on appraisement result have been generated with fan-shaped units and annular units.Based on these pictures, therestructure and regularity.some analysises of land use distribution, structure and regularity.As one of the applications, intensive use tendency of overall urban land is simply analysed with appraisement results and calculated potential size in this paper.This analysis comprises city land reserve resource amount, city population and land use increase elasticity, input and land use increase elasticity,output and land use increase elasticity. Besides, the assistant evaluation with computer especially geography information system is helpfully explored.At the end of this thesis, there is a brief summing up of this study's major contents which includes the breakthrough of theory, innovation of technology and application prospect Some deficiencies and questions that require further study put forward.
