Urban land is the foundation of urban social and economical development. The different degree of urban land use brings about different economical, social and environmental benefits to urban areas. Now, the land resource of our country becomes tenser day by day. The low level of urban land use has caused waste and the reduction of land benefit . To raise the intensivism and realize the sustainable use of urban land, this paper adopts geography information system as major technology to discuss the evaluation of urban land intensive use and potential. All of them are based on drawing the foundation of domestic and international advanced related theories, research technique and actual inquiry. Jinan city is the case of this study.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 Jinan city, we make simple discuss on the present situation, potential size and intensive use tendency of urban land in districts of Jinan city.On practice aspect, the status quo of urban land intensive use in Jinan 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 Jinan 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 the2derived 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 land 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, there are some analysises of land use distribution, structure and regularity.As one of the applications, the 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 are put forward.
