- 摘要:
- 以济南市为例,选取与土地利用效益相关的指标,建立城市土地利用效益指标评价体系,将熵权法与综合评价法有机结合,进行济南市土地利用效益评价研究.研究中根据熵理论,采用熵权法计算各个指标的权重值.采用加权指数和法,计算出1995-200年的济南市土地利用效益综合指数.结果显示,1995年以来济南市土地利用效益基本呈上升趋势,特别是1997年以后土地利用效益出现了明显上升趋势,但是间或有小波动.通过分析济南市9a来土地利用效益的动态变化过程,为济南市的发展提供一些提高土地利用效益的有效建议.
- Abstract:
- Abstract:An index system of benifits assessment of urban land use in Ji’nan City is set up by selecting essiential certain indexes related with benifits of land use.By the combination of entropy-right method and comprehensive appraisal method,this paper makes an assessment on the urban land use benefits.The paper uses entropy-right method to calculate the weights of assessment indices and uses weighted index summation method to calculate the integration index of land use benefits at the time scale(1995-2003) in Ji’nan city.The results shows that the urban land use benefits are increasing since 1995,especially the land use benefits are clearly increasing after 1997,but with a small fluctuation sometimes.The paper analyzes the dynamic changes of the past nine years in Ji’nan city,which are useful in concluding suggestions for the further development of land use of Ji’nan city.
