The suburbs are emerging with the development of urbanization to in special geographical entity between rural and urban, is affected by urbanization, industrialization process most significant, the most sensitive, the most acute contradiction between people and land area. From the urban and rural suburb subject to various forces, it is also the specific location of this area makes it the most significant characteristics of land use is different from other regions is a complex structure of land use, extremely unstable, always is in constant flux. At present, China has entered a stage of rapid urbanization, suburban land use changes in the structure will be increasingly keen as the socio-economic development, the accelerated process of urbanization. Land resources is the resource base for sustainable socio-economic development in the entire region the land resources directly related to the sustainable use of regional socio-economic strategy of sustainable development could be achieved. The outskirts of the city yesterday, the village tomorrow, accelerated urbanization, industrialization process of China's social and economic development of the inevitable, as the most significantly affected areas, the suburbs of big cities in the process of urbanization in how to maintain the sustainable development of the regional economy resource base, to achieve the goal of sustainable use of land resources, and played draw with the demonstration of the role of the other regions, \Therefore, the dynamic mechanism of suburban land use structure change and land resources for sustainable use evaluation study has important practical significance. The suburbs is a new geographical entity, domestic and foreign scholars have different views its conceptual and geographical space defined, the paper first summarizes the different understanding of the respective school and academics on the outskirts of, on this basis, to explore the suburbs different land use and structural characteristics with other regions. Then through the transverse the contrast and longitudinal analysis of several typical big city suburbs land use data, summarized, summarize, reveals a number of general characteristics of the different the Typical Year suburban land resources in the process of urbanization configuration, so as to arrive urbanization land use structure change in the outskirts of the general law, pointed out that the agricultural land, especially the sharp reduction of arable land resources has become the most significant features of the suburban land use structure change. This suburban land use structure variation generated not by chance, but a deep inner motivation mechanism, this mechanism were discussed from the micro and macro levels. Through micro-economic analysis of suburban land use structure change, reveals a marginal revenue driven by the change of the structure of suburban land use; macro reveals the economic development of the urban area, the transfer of population and industrial space, improve transportation conditions, land management system the role and influence of factors such as peri-urban land use change, the system demonstrates the dynamic mechanism of peri-urban land use change. Then from the connotation of sustainable use of land resources, combined with the characteristics of the suburb itself, Suburban Land sustainable use evaluation index system is constructed from three sides of the ecological, economic, social. Finally, Jiangning District, for example on the basis of theoretical analysis empirical research. Quantitative depth analysis of the mechanism of the interaction of suburban land use structure and its driving force, the use of multiple regression analysis model and the use of CM (1,1) model fitting analysis of land use structure change of Jiangning District, the establishment of the city process of change of land use structure in Jiangning District, CM (1,1) prediction model, the model predicted results show that the Jiangning District of reducing the speed of the arable land in the future urbanization will accelerate, Jiangning will continue to face, especially agricultural land sharp drop of arable land resources. Use of the theoretical part of the build sustainable land use evaluation index system of Jiangning District of evaluation results also show that land use in the late 20th century, Jiangning District by unsustainable use of to reach barely sustainable use of state from 1995 to 2000, and the sustainable utilization levels have been increased, but the ecological land use reasonable index is very low, while the arable land also dropped. From the organization on the basis of the above theoretical and empirical analysis, innovation, technological innovation, management innovation, and policy innovation perspective, sustainable utilization of land resources, such as urbanization and industrialization policy, land economic (price) policy.
