Land use in urban development plays an important role, and land use inputs and outputs are the core of land use. After summarizing results of previous studies on land use, this paper attempts to analyze the condition of land use in inputs and outputs in Wuhan city from the urban land intensive use. First, according to the characteristics of land intensive use, we built a set of land intensive use evaluation system; second, we used entropy techniques to determine the weights of index, and calculate the cities’ evaluation value of intensity of land investment and land-use efficiency. Finally, we compared the evaluation values of Wuhan city in 2003-2007 with Chongqing, Nanjing and Shanghai city. The results showed that Wuhan land use input and output levels are significantly higher than the overall average and it is an upward trend. However, Wuhan land use output levels decreased by 20.70% in 2006 compared with 2005, and increased by 21.63% in 2007 compared with 2006 but still slightly below the level of 2005. Units of the total land area of fixed assets and unit of added values of lands used for industry and servica sector are the largest contribution in land use inputs and outputs of Wuhan city.
