Evaluation of urban land use performance and diagnosis of its obstacle degree are the important basis for sustainable land use. We selected Daqing City as the study area. The evaluation index system was built based on land use input level, land use degree, land use benefit, and land use ecological sustainability. The improved TOPSIS model and obstacle degree model were used to assess urban land use performance and diagnose its obstacle indicators of Daqing City from 2001 to 2010. Results showed that,during the period from 2001 to 2010 the level of urban land use performance in Daqing was generally increasing, with the performance index increasing from 0.290 0 to 0.715 4; the urban land use performance experienced low level to good level; the obstacle degree of land use degree and land use ecological sustainability increased by the annual average of 1.91% and 1.38%, respectively, but the obstacle degree of land use benefit and land use input level decreased by the annual average of 2.52% and 0.76%, respectively. The land use degree was found to be the major obstacle degree on affecting future urban land use performance, increasing the land use degree was crucial to the urban land use performance improvement.
