甘肃省全国重点文物保护单位时空分布及其成因

Spatio-temporal distribution and forming factors of national key cultural relics protection units in Gansu Province

以甘肃省全国重点文物保护单位为研究对象,基于地理信息空间分析技术,借助GIS等工具,对甘肃省国保单位的时间演变与空间布局及其影响因素进行了探究。结果表明,甘肃国保单位的分布整体呈集聚分布类型,密集区主要分布于丝绸之路沿线地区;在时间上则主要集中于魏晋南北朝与明清时期;就时空演变而言,分布重心显现出东南—西北—东南迂回移动的趋势。分析其布局成因,发现自然因素与社会因素的交互对国保单位时空类型格局的形成具有协同驱动的作用。据此对文物保护和开发利用提出了针对性建议。

Taking the national key cultural relics protection units in Gansu Province as the research object,based on the spatial analysis technology of geographic information,the time evolution,spatial distribution characteristics and influencing factors of cultural relics in Gansu Province is studied through GIS and other quantitative analysis tools.It presents that the distribution of cultural relics in Gansu Province is in the form of aggregation distribution as a whole,which has significant regional differences in regional space,and there are also significant stage characteristics in each historical period.By analyzing the causes of its layout,it is found that the interaction of natural factors and social factors has a synergistic driving effect on the formation of the spatio-temporal pattern of national key cultural relics protection units.Based on this,some suggestions are put forward for the protection and utilization of cultural relics.
