| 摘 要： | 结合庆阳市西峰区土地利用现状,遵循一定的科学原则和相关理论,建立了以土地利用综合效益为总目标,土地利用经济效益、社会效益和生态效益为子目标,包括24个评价指标的土地利用综合效益评价指标体系。以庆阳市西峰区的土地利用变更数据以及西峰区统计年鉴的各项数据为基础,采用变异系数法确定指标权重,运用TOPSIS评价模型对1996～2008年庆阳市西峰区的土地利用效益进行评价。结果表明,西峰区土地利用综合效益、经济效益和社会效益呈逐年上升趋势,生态效益呈现先下降后上升的变化趋势。

| Abstract: | Based on the analysis of land use status in Xifeng District of Qingyang City and according to related scientific principles,the evaluation indicators system was established for land use efficiency from the aspects of economy,society and ecology which consists of 24 evaluating indicators.The land-use data and socio-economic statistical data of Xifeng District form 1996-2008 was used in the paper.With the variation coefficient methods,the weight of every index was calculated,and the land use efficiency in Xifeng District were evaluated and analyzed by the TOPSIS model.The results showed that land use efficiency of Xifeng District kept growing from 1996 to 2008.Economic and social efficiencies had the same trend as comprehensive efficiency,while the ecology efficiency decreased at first and increased later. |
