本文采用层次分析法构建了土地集约利用评价指标体系,并确定了各指标权重;运用功效函数法计算了土地集约利用度(LIUI);依据探索性空间数据分析(ESDA)原理,在GEODA支持下计算了全局空间自相关Moran I指数与Local Moran I指数,分别检验土地集约利用度的全局空间相关性和局部空间相关性;最后在ARCGIS支持下绘制了陕西省土地集约利用度空间分异图与土地集约利用度LISA图,揭示了LIUI的空间分异。
This paper used AHP to construct the evaluation indicator system of land intensive use, determined the weight of every targets, and calculated the LIUI ( Land Intensive Use Index) by the method of effect function. Then it calculated the Moran I index and Local Moran I index under GEODA support based on ESDA. Finally the paper drew up the space differentiation charts of Land Intensive Use Index and LISA of Shaanxi Province under ARCGIS support.
