【摘要】：大数据时代的到来为历史学研究带来了机遇和挑战,尤其是在历史文献资料较为缺乏的西南山区,如何获取丰富的数据资料进行科学研究成为摆在历史学研究者面前的一大难题。本文综合利用文献资料和田野调查等多学科方法,以及数据库和GIS等手段,以聚落为研究西南山地小区域环境变化的载体数据,获取了丰富的多源数据,创建了具有连续时间序列的流域聚落信息数据库,量化分析了自然因素中地形和坡向对山地环境变化的影响。研究认为,在掌鸠河流域,不同地形区对聚落空间演变和环境变化的影响具有明显的时间动态性,坡向的影响则并不显著。本文为大数据时代下综合利用多学科方法和多技术手段研究西南山地小区域环境变化提供了一个典型的案例参照。
[Abstract]:The arrival of big data brought opportunities and challenges to the study of history, especially in the mountainous areas of southwest China, where historical documents were scarce. How to obtain abundant data for scientific research has become a difficult problem for history researchers. In this paper, comprehensive use of literature, field investigation and other multidisciplinary methods, as well as database and GIS, to study the settlement as the carrier data for the study of environmental change in small mountainous regions in southwest China, obtained a wealth of multi-source data. A watershed settlement information database with continuous time series was established, and the influence of topography and slope direction on the mountain environment was analyzed quantitatively. It is concluded that in the Zhangjiu River basin, the influence of different topographic areas on the evolution of settlement space and environment is obviously time-dynamic, but the influence of slope direction is not significant. This paper provides a typical case reference for the study of environmental change in small mountainous regions of southwest China by comprehensive use of multidisciplinary methods and techniques in big data's time.
