摘要
利用地理信息系统空间分析技术,结合工程地质条件和气候因素,研究甘肃省内全国重点文物保护和省级文物保护土遗址的空间分布特征.土遗址主要位于海拔相对较低(<2 000 m)、坡度较缓(<15°)、地形起伏度小(<5 m)、离河流近(<5 km)的平原、台地和丘陵地带.大多数土遗址位于第四纪沉积物沉积区域,区域土壤主要为初育土.河西走廊及以西地区的土遗址处于干旱、半干旱区,东部土遗址处于半湿润区,土遗址所处区域自南至北的气候有显著差异.通过ArcGIS软件的核密度分析发现,甘肃省重点土遗址自西向东分布密度逐渐变大,且整体沿甘肃省的主要水系干流及其支流展开分布.各历史时期的土遗址选址因其功能性而异,主要受地质环境条件的制约,也受社会生产力的影响.
Geographic information system spatial analysis techniques were employed to investigate into the spatial distribution characteristics of national and provincial protected earthen heritage sites in Gansu Province,with a focus on engineering geological conditions and climate factors.These sites are predominantly situated in plains,plateaus and hills characterized by a low altitude(<2000 m),gentle slope(<15°),small topographic relief(<5 m)and proximity to rivers(<5 km),with the majority of them being located in Quaternary sedimentary areas and featuring predominantly primary soils.The earthen heritage sites in the Hexi Corridor and western regions of the province are in arid and semi-arid zones,while those in the east in semi-humid areas.There are significant differences in the climate of the regions where the earthen heritage sites are located from south to north.Through the kernel density analysis via the ArcGIS software,it was found that the density of earthen heritage sites in Gansu Province gradually increased from west to east,and were generally distributed along the main rivers and tributaries of the province.The selection of earthen heritage sites in different historical periods had been different due to their functional characteristics,which were mainly constrained by geological environmental conditions and also influenced by social productivity.
