无定河上游明清时期通哈拉克泊的定位研究
首发时间:2019-05-09
摘要:通过地形分析,历史地图解读,历史文献分析,遥感影像判读,明代边墙选址讨论,结合萨拉乌苏河地层剖面的研究成果,本文对无定河上游可能存在的通哈拉克泊进行了重新定位。结果表明明清时期历史地图记载中的通哈拉克泊并非之前历史地理研究者认为的城川北侧湖泊遗迹,而是位于定边和宁条梁之间的低平地带。由于该地湖泊及南侧湿地的存在,这一区域长期以来缺少人类活动,还导致明边墙在安边向南转一个大U形弯。相应结果为重建无定河上游的历史景观提供了基本信息,改变了长期以来该区历史地理的认知,因此具有重要意义。

Relocaitong of the Ming-Qing's Lake Tonghalake
Abstract:The Lake Tonghalake was an ancient lake drawn in some Ming-Qing maps. Former studies considered that it was located at the north of Chengchuan, where a dried-up lake remains presently. However, based on the interpretation of historical map and remote sensing images, analysis of historical texts and the location of the Ming Great Wall, the authors found that it was actually located at a marsh area between Anbian and Ningtiaoliang. The result corrected former knowledge and provided good explanations for the U shape of the Ming Great Wall of the region. The methodology introduced in the paper would shed new light on the reconstruction of regional landscape of historical time
