摘要:
受自然环境和资料限制的原因,中国西北的季风边缘区内的湖泊千-百年时间尺度演变序列重建工作存在不足.历史文献中的湖泊演变信息丰富,有效利用可较好地解决这一问题.本文通过梳理历史文献记录的定边盐湖采盐方式资料,反演历史时期定边盐湖卤水水位,重建公元1265-1949年陕北定边盐湖卤水水位演变序列,该序列较好地指示出公元1265-1949年间定边盐湖所处区域的气候干湿变化状况.重建结果显示,定边盐湖所处区域在公元1265-1949年间存在2个湿润期和3个干旱期,影响该区域气候干湿变化的主要原因为东亚夏季风的强弱变化.本文研究证明历史文献中的湖泊演变信息是一类科学的自然代用指标,其便于收集、物理逻辑清晰,但时间分辨率稍显不足,若能与传统湖泊沉积资料有效结合,具有更广阔的研究前景.

Abstract:
Due to the limitation of physical environment and data, the reconstruction of lake evolution at thousand/hundred year scales in the monsoon marginal zone of northwestern China has remains insufficient. The lake evolution information in historical documents is abundant, which can help better understand this issue. This paper combs the salt mining method data of Dingbian salt lakes recorded in historical documents, inverts the brine level of Dingbian salt lakes in the historical period, and reconstructs the evolution sequence of the brine level of Dingbian salt lakes in northern Shaanxi Province from 1265 A.D. to 1949 A.D.. We suggest that this sequence is a good indication of the climate change in the area from 1265 A.D. to 1949 A.D.. The reconstruction results show that there were two humid periods and three drought periods in the area over 1265-1949 A.D.. The main reason for the climage changes in this area was the intensity variation of the East Asian summer monsoon. Our research proves that the salt lake evolution information in historical literature is a kind of alternative indicator. It is easily available and has clear physical logic, but the time resolution is slightly ambiguous. Being combine with traditional lake sedimentation data, it will have a much broader study prospect.
