摘要
作为建设用地的重要组成部分,工业用地的节约集约利用直接影响到建设用地特别是城市土地利用和管理的效果。基于开发区的工业用地集约利用评价能分析开发区土地集约利用现状,揭示不同区域及不同类型开发区土地集约利用的差异,为促进开发区土地资源高效利用提供参考。以江苏省为例,通过构建包含开发程度、用地结构、用地强度、用地效益和资源消耗5个子目标、14个指标的开发区土地集约利用评价指标体系,采用RAGA-AHP方法实现了江苏省134个开发区土地集约利用评价。研究结果表明:实码加速遗传算法与层次分析法的集成,能获得高精度的权数并能保证全局收敛性;江苏省开发区土地集约利用水平存在较大的区域差异性,苏北5市开发区土地集约利用的总体水平远低于苏南和苏中地区,但苏南和苏中地区开发区土地集约利用的总体水平差距较小;高新技术开发区比其他类型开发区的土地集约利用水平高;国家级开发区的土地集约利用水平按开发区类型出现较大分异。
As an important part of construction land,industrial land intensive use has effect on the management of urban land.Evaluation of land intensive use from industrial land makes for explaining the current state and differences between various industrial land intensive uses,which can provide some references for efficient land use.As a case study of development areas in Jiangsu Province,we established the index system,including exploitation level,land use structure,land use intensity,land use benefits and resource consume with 5 sub-goals and 14 indices,in order to evaluate the industrial land intensive use with RAGA-AHP.The results indicate that high weight precision and global convergence can be acquired with RAGA-AHP.The different of industrial land intensive use is remarkable as a whole in Jiangsu Province.The land use intensity of development areas in northern Jiangsu is less than that of southern and middle Jiangsu.However,there are little differences between southern and middle Jiangsu.The land use intensity of high-tech development areas is more than other kinds of development areas.In addition,the land use intensity shows remarkable differences between national development areas with regard to the kinds of development areas.
