An Evaluation Model for the Low-carbon and Intensive Urban Land Use Using Analytic Network Process
构建了基于网络层次分析法的低碳集约城市土地利用评价模型，以南京市为例进行实证分析，发现GDP、单位面积碳排放和人均建设用地是主要影响因素，1998-2009年发展水平呈上升趋势。
The purpose of this study is to build theoretical basis and practical application of intensive urban land use based on low-carbon economy.As for the mutual correlation and feedback among elements in the evaluation indicator system,Analytic Network Process was chosen to build evaluation model and determine the weight of indexes.Examination of the results provides a time series analysis of Nanjing City and uses Super Decision software to empirical calculations.Methods of system analysis and ANP method were employed.The results indicate:(1) The main factors affecting the low-carbon and intensive urban land use are GDP and carbon emissions per unit area of land,construction land per capita,etc..(2) The development level of low-carbon and intensive urban land use had a ascend trend,the index increasing from 0.41 to 0.55,with an average annual growth rate of 2.72%,during the period 1998-2009.(3) The carbon emissions and sustainability of land are the main barrier factors,which should be reformed.The conclusion of study is that ANP method and proposed model can objectively reflect the development level and trend of urban land use system.
