历史地理数据的GIS应用处理——以清时期的陕西为例

GIS Data Processing of Historical Records--The Case of the Qing Dynasty in Shaanxi

基于 GIS数据处理技术 ,对清时期陕西省内的县级政区境界做出数字化建库 ,并链接历史文献中的县级人口、耕地等专题数据 ,进行了人口分布与人口密度、耕地分布与垦殖密度等方面的数据分析和制图。

With GIS data processing, the historical records of county boundary, population distribution, farmland statistics and cultural phenomenon in Shaanxi Province during the Qing Dynasty were transformed into digital database which is composed of the GIS analysis platform for further study of the man-land relationship during historical period.For county level historical boundary, there are several guidance to follow, such as the records of major rivers, towns and residencial areas; the compilation of ancient maps; the watershed divide, etc. For the population distribution data, the number was linked to the county's name, and with the careful evaluation, the data on each county of Shaanxi province in the late Qing dynasty was credible for GIS processing.For the farmland records, the unit of mu(one mu equals to 1/15 ha) is a variance in different regions. While,there are only the raw records for processing, from which, reasonable analysis could be achieved with local geographical ideas.
