Study On Evaluation Of Sustainable Urban Land Use

The urban land is the foundation of city forms and development, is the carrier of city society,economy,politics,culture and so on, therefore city land's rational utilization, directly related to the sustainability of city vicissitude and region economy growth. Compared with farmland use, forestland use and so on, The process of urban land use is more complicated. Except the land resource's common characters such as limited quantity, space stationary, supplies scarce, the continues use, city land has type multiplicity, in the use function structure complexity, the land position extreme importance and uses on highly intensive. Therefore, the city land sustainable use is to satisfy economic growth to the land demand, maintains and enhances land use structure and the use way with the person to occupy reasonable, the economy is feasible and the social justice. How to use the city land effectively and forms the reasonable city land spatial structure, enable the city land to tend to the sustainable use, is one of the problem that is concerned by the urban economics, the city geography and the urban sociology.This article discussed the related theory of sustainable land use, the basic connotation of sustainable land use evaluation, and to find out the sustainable development and the land utilization union way base on summarizes and analysis the research on sustainable land use in the domestic and international. Take Urumqi, which with the fast urbanization development and the prominent person-land contradictory as an example, analysis the natural environment, economy, industrial structure and population character of Urumqi. Then built the evaluating index system of sustainable land use from the resources and environment, economy, and society. Calculated weight of each index with Analytic Hierarchy Process and Delphi method, and got the level of land sustainable use of Urumqi with multi- goals linear adding weight method and the model of obstacle degree, which found out obstacle factors affecting the urban land use. Consequently puts forward several measures to the sustainable development of this city, which is based on the analysis of the evaluation results and the obstacle factors.Finally give out the conclusion of the article, points out the possible innovation and further studies.
