摘 要:研究目的:对2006年全国31个省、直辖市、自治区的交通用地集约利用水平进行综合评价,提出全国交通用地集约利用相关政策建议。研究方法:针对交通用地集约利用评价系统的多目标和指标间的不相容性,提出交通用地集约利用综合评价的遗传投影寻踪模型。研究结果:(1)全国公路与铁路用地集约利用水平以及交通用地投入产出经济效益对集约利用水平影响较大。(2)2006年全国交通用地集约利用水平呈现东南—西北依次递减趋势。研究结论:遗传投影寻踪模型采用"直接审视数据—通过计算机模拟数据结构—评价"的新途径,为交通用地集约利用研究提供了新的思路和参考依据。The purpose of the paper is to comprehensively assess the intensity of traffic land in 31 provincial level regions (including provinces, municipalities directly under the central government, and autonomous regions) in China in 2006, so as to put forward relevant suggestions for the intensive use of national traffic land. Method employed is to build a comprehensive system on intensive traffic land use assessment through the genetic projection pursuit model, aiming to solve the incompatibility between the multi-objectives and indices of the assessment system. The results include: ( 1 )the intensive use levels in China are significantly affected by the input and output economic benefit of the traffic land, and (2)the intensive levels of national traffic land use presented a decreasing trend geographically from southeast to northwest in 2006. It is concluded that the new approach of "directly surveying the data + stimulating the data structure by computer + assessing" adopted by the genetic projection pursuit model brings new ways and references for studying the intensive use of traffic land.
