摘要
以甘肃省为例,根据其14个地州市2000-2007年土地利用变更数据和有关社会经济数据,从土地集约利用和经济发展角度构建评价指标体系,通过基于熵权法的多因素综合评价方法,对甘肃省八年间的土地集约利用水平和经济发展水平进行评价,并运用统计方法,对比分析了甘肃省土地经济集约利用和经济发展水平的时空差异特征以及二者的相关度。结果表明:①从时间变化特征来看,甘肃省总体上表现为经济发展稳定上升,地区发展趋势一致,而土地集约利用度整体上呈现波动上升;②从空间变化特征来看,土地集约利用程度和经济发展水平整体上都表现为河西地区>陇中地区>陇东地区>陇南和甘南地区的特点。
Taking Gansu Province as an example,based on the data of land use and economic statistics from 2000 to 2007 of 14 cities of it,the paper investigated land intensive use and local economic development.By constructing evaluation system from perspective of land intensive use and economic development,and entropy-based multi-factors comprehensive evaluation,the level of land intensive use and economic development of this 8 years was evaluated.In addition,statistical method was used to compare and analyze the spatial-temporal variation of land intensive use and economic development,and the correlation between them in Gansu province.The results indicated that： ①in the aspect of temporal characteristics,it showed a steady increase in economic development in general the whole province and regional economic development trends in line.But the level of land intensive use had a fluctuant increase and regional differences were significant.②in the aspect of spatial characteristics,the trait of the level of land intensive use and economic development were both that Hexi regionLongzhong regionLongdong regionLongnan region and Gannan region.
