| 摘 要： | 基于经济、效益、效率和公平的4E土地利用绩效评价框架和ESDA-GIS空间分析方法,对甘肃省县域土地利用绩效及其协调度进行了测度,并探讨其空间格局的形成机制.结果表明,甘肃省域范围内土地利用绩效水平呈现西高东低,北高南低的格局;经济绩效与效益绩效呈现较强的空间集聚特征,效率绩效与公平绩效的空间分布趋势较为离散;土地利用绩效的空间聚类可以划分为4种俱乐部趋同类型,高绩效和低绩效趋同俱乐部的空间分布最广,稳定性最大;绩效内部的协调度体现为高值区带动下的区域整体水平趋高,但协调度并不与经济发展水平成单纯的正比关系.ESDA-GIS空间分析方法可以清楚地解释土地利用绩效水平的空间异质性问题,并且具有直观的可视化效果.

| Abstract: | The performance of county land use and its coordination degree in Gansu Province are measured,and the formation mechanism of its spatial pattern is discussed based on ESDA(exploratory spatial data analysis) methods and spatial4E(economic,effectiveness,efficiency and equity) appraisal framework.The results indicate that the spatial pattern of land use performance level in Gansu Province is more advanced in north-western region than south-eastern region.The performances of economy and effectiveness show stron... |
