城市土地利用效益的空间差异研究——以甘肃省为例

Study on Spatial Differences of Benefits Evaluation in Urban Land Use—Setting Gansu Province as an Example

摘要:

立足于社会、经济和生态环境等方面建立城市土地利用效益评价指标体系，并借助熵值法和聚类分析相结合的方法，探讨了甘肃省各城市土地利用效益水平现状及其空间差异。结果表明：甘肃省各城市土地利用效益水平均不高，且区域差异明显，整体呈现“西高东低，南北分化”的格局，空间上体现出“阶梯状”区域梯度递减的分异结构特征；产生空间差异的原因有自然条件、区位差异和产业结构等因素；最后，根据各城市具体情况提出针对性优化对策和建议。

Abstract:

In this paper, an indicator system is put forward to evaluate the efficiency of land use from the view of social benefit, economic benefit, and environmental benefit. By using entropy method and cluster analysis, present conditions and benefit diffenences of urban land use in 14 cities in Gansu Province have been studied comprehensively. It is showed that :there is a significant spatial difference of land use efficiency in Gansu province. The level of natural conditions, location difference and industry structure are all the indicators affecting the spatial differences. Some countermeasures and suggestions have been put forward to optimize the spatial differences of land use efficiency according to the characteristics of land use in different regions in Gansu province.
