Study On Evaluation Of Urban Land Intensive Utilization

Launching the intensive utilization evaluation of urban land, realizing the actuality and main problems of urban land intensive utilization in a quantificational way, finding out the countermeasures to improve efficiency of urban land utilization, is good for promoting rational distribution and rational utilization of the urban land resource, transform epitaxy expand to the combination of epitaxy expand and latent power expand.The meaning of urban land intensive utilization, the research contents, the research methods and the technical line were deeply researched in this paper. The basic characteristics and format of urban land intensive utilization, the relation between intensive utilization and relatable conceptions were introduced particularly. The principles, the theoretical gist of urban land intensive utilization and the basic theories of the evaluation method which included AHP, Delphi and multi-target grading method were analyzed. On the basic of general situation and the urban land utilization state of Changsha city, the index system of evaluation which include four rule layers, fifteen factor layers, thirty-one index were fixed on by the methods of Goal method and cause and effect method. The proportion of evaluation index was confirmed on using the method that combined AHP with Delphi. After dealing the evaluation index with dimensionless mode, the result of Changsha city's urban land utilization was ascertained by the multi-target grading method. The level of intensive utilization was at basic intensive stage from 2000 to 2004 at the Scores of 0.625,0.629,0.690,0.688,0.708,and it was ascending in a curvilinear way. On the basic of analyzing the evaluation results, the author advanced four hurdle factors which blocked urban land intensive utilization off. The four hurdle factors were the lack of devotion to urban land, the low output of urban land utilization, the low rationality of urban land utilization, the farther enhancement of urban land's environment. At last, the author put forward the measures to make urban land utilization in intensive way.
