历史时期高原浅水湖泊变迁的复原方法研究———以明清以来嘉丽泽演变为例

历史时期云贵高原遍布浅水湖泊,这些湖泊的演变多与人类活动相关,是历史自然地理研究的重要问题。本文探索了综合利用地名志、地方志和相关历史文献,发掘老地图的相关地理信息,并利用遥感ＤＥＭ数据,以及ＧＩＳ技术等多学科方法,重建高原浅水湖泊演变的方法,并成功重建了１５世纪中叶以来云南嵩明嘉丽泽多个时间断面的湖泊水面,垂直分辨率达到１米,据此讨论了嘉丽泽的演变及消亡的过程。这一目前对历史时期湖泊演变的研究中分辨率最高的研究,为进一步研究高原浅水湖泊的历史演变提供了方法的范例。

Reconstruction method for the study of the evolution of shallow plateau lakes in history:A case study of Jialize Lake

There were many shallow lakes distributed on Yunnan Guizhou Plateau in history. The evolution of these shallow lakes through the ups and downs in history is usually connected with human activities, which becomes a key issue in the studies of historical geography. This paper uses the multidisciplinary approach by integrating local gazetteers, related historical literatures, ancient maps, DEM data and GIS method for the reconstruction of the typical changes of Jialize Lake in Songming County at different times since the middle 15th century, with its vertical resolution of one meter, the best of its kind up to now. This study of the changes and disappearance of Jialize Lake provides a good approach to a further study of the historical changes of the shallow plateau lakes.
