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

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

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。

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 tures ,ancient maps , DEM data and GIS method for the reconstruction of the typical changes of Jialize Lake in Songming Countyat 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.
