Abstract: Based on the data about urban development and water environmental quality in oasis cities of Tarim Basin from 2004 to 2017, the relationship between urban development and water environmental quality was debated in this study. First, the level of urban development was charactered by sixteen indexes of population, economy, space and society, and the water environmental quality was quantified by twelve indexes of water environmental pressure, water environmental protection and urban water supply. The weights of indexes were confirmed by Coefficient of Variation (COV) and entropy theory. Second, comprehensive evaluation models were built to analyze the change of urban development level and water environmental quality. Finally, the model describing coordination degree between urban development and water environmental quality was constructed and improved repeatedly to quantitatively evaluate the coordination relationship of oasis city of Tarim Basin. The result showed that:(1)The trend of comprehensive index of urban development rose stability in oasis city of Tarim Basin, and the main development's form was economic development and urban space had been expanding. The urban population scale was increasing and the urban society also reflected the similar development trend with comprehensive index of urban development. (2)The comprehensive index of water environmental quality showed a tendency that was getting hitched. Water environmental pressure, water environmental protection and urban water supply were declining gradually. (3)Take the space analysis of coordination degree between urban development water environmental quality in oasis cities of Tarim Basin with GIS, the result shows that the coordination degree between urban development and water environmental quality systems increased first and then decreased. On the whole, the coordination degree in the past years was low and the collide between the two systems has been faced stiff competition.

Key words: oasis city, urban development, water environmental quality, coordination degree, Tarim Basin
