Tengzhou City Land Expand Evaluation Research

Over the past20years, the rapid advance of urbanization in our country and the accelerating development of social economy make the city space expanded sharply, caused the urban space disorder, lack of land used for urban internal environmental degradation, structural, inefficient land use change, the lack of urban space characteristics and a series of urban problems.At home and abroad in terms of how to objectively evaluate the quality of urban land expansion research is weak. Scientifically establishing urban land expansion, therefore, evaluation standards and contents, and build up a set of relatively perfect and reasonable evaluation index system, timely analysis of the past mistakes, urban construction and guide the expansion of the urban land more reasonable correctly, has great practical significance and theoretical significance.Summary is presented in this paper, carding domestic and foreign authoritative research theory and the relevant evaluation method, on the basis of combining the present situation of our urban land expansion in recent years, puts forward how to urban land expansion is reasonable, and establish the connotation of urban land expansion rationality. According to the existing problems and the connotation of urban land expansion rationality step by step to establish evaluation criteria, evaluation index and index selection factors, build system, perfecting the evaluation index system of as much as possible.In tengzhou, for example, the selection status of urban land use extension evaluation index, using the appropriate evaluation method to su made an evaluation of the rationality of urban land expansion, in view of the problems exposed in the evaluation results of the corresponding planning countermeasures are put forward. This thesis is divided into four parts altogether, a total of six chapters:The first part contains papers of the first and second chapter, carries on the evaluation system of urban land expansion research background, purpose, significance, research contents, research methods and research framework, and the relevant evaluation index system and evaluation method of research at home and abroad were reviewed.The second part includes the third and fourth chapter of the paper, based on the current mainstream of urban development, combined with China’s specific national conditions, puts forward the concept of urban land expansion rationality:"as long as conducive to sustained economic prosperity, social harmony and stability, promoting city environment comfortable, space characteristic of urban land expansion of urban land expansion is reasonable. Its basic performance is:ensure that the quality of the urban quality continued inheritance in the time dimension, the new function can timely find suitable land for development." Then from the economic, social, environmental and space layout of the four aspects respectively expounds the connotation of urban land expansion rationality. According to the connotation of urban land expansion rationality, established the urban land expansion of the evaluation principles, evaluation index system, and select the appropriate evaluation method. In addition, the meaning of every evaluation factor and measure has carried on the detailed explanation, also provide the basis for the empirical evaluation.Chapter5of the third part is the thesis, first of all, from the overall to tengzhou in1995-2012, the urban land expansion situation were summarized, and for residential and industrial land extension process and public center shift process are analyzed. Then according to tengzhou development characteristics and existing research data access to select suitable for su evaluation index system of urban land expansion, to su in1995,2006and2012, three years of urban land assignment of each index factor was calculated, points, and the score of every index layer is obtained. According to the scores obtained for17years to analyze pros and cons of urban land expansion, and needle problems put forward the corresponding countermeasures.Fourth part is the thesis of the chapter6, to summarize the study, inductive paper innovation points, pointed out the deficiency, the thesis reference for later research.
