| 摘 要： | 土地是城市发展的基础资源，土地利用的投入与产出是土地利用效益的核心。在总结前人土地利用研究成果的基础上，尝试从城市土地集约利用的角度分析武汉市土地利用的投入与产出效益。首先根据土地集约利用的特点构建一套土地集约利用评价指标体系，其次运用熵技术确定指标的权重，计算城市土地投入强度和土地使用效益的评价值。最后把武汉市2003-2007年的评价值与重庆市、南京市和上海市进行比较分析。结果表明:武汉市土地利用投入与产出的总体水平都明显高于平均值且呈上升趋势，但是武汉市土地利用产出水平2006年比2005年下降了20.70%，2007年比2006年上升了21.63%，但仍略低于2005年的水平；单位土地面积固定资产总额和二、三产业增加值对武汉市土地利用投入与产出的贡献度最大。

| Abstract: | 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. |
