Research On Urban Land Classification In Liaoning Province Based On GIS Technology

In recent years, with China’s rapid social and economic development, coupled with the urbanization process significantly faster, resulting in the continuous expansion of urban construction land use range is severely degraded, land supply and demand have become increasingly prominent. This rational and efficient use of land resources, asked for a higher demand. Reform and opening up, especially since the urban land compensation for the use of the system to determine, reflect on the following micro-urban income differentials within the land grading and land classification reflect differences in the quality of land in town have emerged.The combination of Liaoning Province is located in the Bohai Economic Rim and the northeast industrial base with superior natural conditions and geographical advantages. But much less arable land scarce reserve resources and other remains the major land problems faced by the province. Under the supervision of the Government, the development of the land market is also increasingly perfect, but the price of land to determine the standards needed standardization. Meanwhile, in order to ensure the healthy development of the land market, to ensure the preservation and appreciation of state-owned land and the economic value of land brought into full play, as the benchmark premium assessment based on land division plays a particularly important role.The first chapter of this paper basis of the thesis focuses on the circumstances and context of urban land division, and the importance of China’s land classification work. Emphasis on research status analyzed and summarized from the establishment of the index system, the choice of the factors that factor, the use of technical methods and practice application of the four angles of the Work of the land classification of the comb is the topics of this article key. Theories and methods of the second article, the theoretical basis in part through the elaboration of the rent theory, land theory of value, land supply and demand theory, laid the theoretical support for research. Explore two ideas of the academic work for the land classification study to determine the ideas of this study. The core of the article, the second chapter three, four, of the index system for the establishment of specific ideas and indicators to quantify process and method, and a key part of the technical aspects are described. Chapter III takes Liaoning Province as an example, the grading of the integration process as a whole elaborate, and other division results were analyzed and discussed.The paper divides the275grading objects into eight land grating. It is important to balance the practical significance of research results for the benchmark premium space in Liaoning Province in the future, the land classification work in other regions of the country also provides a reference. Article innovation lies in the GIS technology to participate in the work of urban land and indicators system presented the original proposal, while the article in practical application there are certain limitations and the need to improve the part. Overall, this paper has a certain academic value and practical significance.
