Abstract: With three counties and one district of Wuwei City，Gansu Province，China，based on three land use maps in 2000, 2005,and 2010 and relevant data, this paper built an urbanization level evaluation indice system from aspects of economic urbanization, population urbanization and social urbanization, and finally measureed the urbanization level of the study area with the entropy method. An evaluation indice system of water-land resources was established from aspects of social, economical, and ecological benefits, and water-land resources efficiency index was calculated by TOPSIS method. The degree of coupling coordination degree model was estimated on the basis of estimates of the level of urbanization and water-land resources efficiency index, urbanization and water-land resources effective and coordinated development degree, with reference to the type of coordinated development of criteria for the classification, to determine the three counties’development and coordination types in each year, according to the mean of the three counties and one district, the evaluation of the level of urbanization in Wuwei City, and water-land efficiency and the coordinated development degree. The results show that the urbanization level of counties and district of Wuwei City was gradually increased in 2000,2005 and 2010, however, their urbanization was carried out basically based on a lagging model of water-land resources use. The water-land resources benefits presented different variation characteristics. Among them, the values of water-land resources benefits were enhanced step by step in Liangzhou District and Minqin County and gradually went down in Gulang County and Tianzhu County. As for Wuwei City’s district and counties, the coupling level of urbanization and water-land resources benefit was in antagonistic stage. Their level of coodination development degree is not high as a whole with gradually increasing trend and the types of coodination development gradually are changed from uncoodination development to coodination development.

Key words: TOPSIS, urbanization, the effectiveness of and water-land resources, coordination degree level
