The Analysis Of The Potential Of The Urban Land And The Study On The Appropriate Deployment Of The Urban Land

On the background of the scarcity of the earth resources in our country, with the fast development of urbanization and industrilization the demand for the land, especially non-agricultural land increases a lot .As a result, the plowland in a certain region decreases, and the contradiction between man and the land is standing out. According to these above, how to enhance the efficiency in utilizing the urban land to evaluate the reasonable dimension and boundary in the new constructional land, to reduce the pressure of plowland resulted from the dilatation of the land with blindness, becomes a new problem to research on.The essay takes Deyang city as an example.

It investigates in the factors of affecting the utilizing efficiency and benefit of the urban land. It aims at establishing the evaluation means and target system on the potential of utilization intensity of the urban land by the establishment of math matrix on the utilization intensity of city earth, adopting GIS technique to make quantitative analysis on the utilization potential of land in Deyang city ,in order to find out the potential of the utilization of the urban land in this city. At the same time, according to the present condition of the earth potential in Deyang city, it advocates the ways and strategy in developing the earth potential of this city. All these above are to change the extensive condition in using the urban land in constructions, make the city land efficiently deploy and appropriately utilize.The essay divides up in eight parts: part one to part four mainly discuss the utilization of city land, which is the basic economic theories; part five to part six mainly probe in the analytic approaches and applicable technique on the potential of city land; part seven ,which is the emphases, taking Deyang city as an example,analyze and evaluate the earth-developing potential in cities; part eight advocates a way in appropriately deploy urban land.
