摘要
土地作为城市社会经济发展的重要载体,其土地集约利用相对效率已成为制约城市可持续发展的重要问题,长株潭城市化发展对土地集约利用相对效率提出了更高的要求。引入超效率数据包络分析概念,利用投入产出指标分析了长株潭土地集约利用相对效率,阐述城市土地利用结构变化、识别与土地集约利用程度相关的问题。结果显示:(1)长株潭城市土地集约利用相对超效率值2010年都趋于高位;(2)长沙市土地集约利用相对效率变化趋势与长株潭城市群趋同。研究发现长株潭城市群土地利用相对效率还可调配至最佳状态;超效率DEA对定量刻画土地利用集约评价更具实用性。
As an important carrier of social and economic development, the relative efficiency of land intensive use which restricts urban sustainable development has became the main problem, and the urbanization development of Chang-Zhu-Tan puts forward a higher requirement to land intensive use relative efficiency. Through introducing the concept of super-efficiency data envelopment analysis, and using the index of input and output, the land intensive use relative efficiency of Chang-Zhu-Tan was analyzed, and then, the changes of land use structure, identifying some problems which related to land intensive use were expounded. The studying results are as followings： （1） the super efficiency value of intensive land use relative in the year of 2010 all tended to a high level; （2） the changing trend of Changsha city land intensive use relative efficiency was the same to that of Chang-Zhu-Tan urban agglomeration. Therefore, Chang-Zhu-Tan urban agglomeration land use relative efficiency can also allocate to the best state and the super-efficiency DEA of land use has more practicability to quantitatively describe the land use intensive evaluation.
