Study On Economical And Intensive Utilization Of Urban Land In Changle District Of Fujian Province

It is a basic national policy of our country to cherish and make rational use of every inch of land.With the development of our country and progress of human society,urbanization is an inevitable result.Economical and intensive utilization of urban land is an important means to cherish and utilize land rationally.However,there is a waste of land and extensive utilization in real life.Taking Changle District as the research object,and based on in-depth analysis of relevant research and cases at home and abroad,this paper analyzes the relationship between land conservation and intensive use,evaluates the degree of urban land conservation and intensive use quantitatively in Changle District,then analyzes the problems and principles,and puts forward the countermeasures and suggestions.(1)By discussing the connotation of land conservation and intensive use,the paper distinguishes the differences between economical use and intensive use of land in the aspects of concept level,pursuit goal and implementation premise.The former is aimed at land waste,rationally determines the scope of the concept model of urban land use,and reflects the concept of efficient and rational use of land under the scientific development concept.And it embodies the concept of efficient and rational land use dominated by the scientific concept of development;The latter is aimed at the extensive use of land,and it takes the rational layout of urban land as the precondition,reflects the input of funds,technology and other production factors,and increases the ratio of output to input of the unit land.Therefore,it is necessary to construct two sets of evaluation systems to evaluate land economical and intensive use respectively.(2)This paper establishes two sets of index system for land economical evaluation and intensive evaluation respectively.The ideal values of each index are determined by the target value method and the relative city comparison method,and then the weights of relevant indexes are determined by Delphi method.Finally,we use the ideal value proportion method to standardize the index.The comprehensive evaluation indexs of economical using land and intensive using land in Changle is 61.17 and 79.16 respectively.(3)According to the evaluation results,the paper quantitatively analyzes the level of land economical and intensive use in Changle from three aspects as follow:the present situation of land economical and intensive use,the trend of dynamic change and the level of management performance.Except for the intensity of use,the indicator of the rate of decline in the gross output of the unit area and the land supply ratio of the city,all other indicators are at a lower level.It shows that the level of intensive use of land in Changle is still at a low level,and there is extensive utilization of urban land.(4)There are some problems in the economical and intensive use of Changle's land,such as the lack of awareness of the economical and intensive use of land,the imperfect policy of the economical and intensive use of land,the imperfect supervision mechanism and the lax enforcement of law.In view of the problems of economical arid intensive land using in Changle District,the following countermeasures are put forward in this paper:to ordinate and optimize the layout of land use;to implement land quota standards of the construction project strictly,to control the increment of construction land;to promote three-dimensional development,to improve efficiency,to strengthen the management of village land,and to promote the construction land consolidation of countryside actively.
