近20年来青藏高原盐湖沉积与环境演化研究综述

A Review on the Saline Sedimentation and Environmental Evolution of Tibet Plateau in Recent 20 Years

综合分析了最近20年来青藏高原盐湖沉积与环境演化研究的主要成果,着重对青藏高原高盐湖沉积的年代学研究、盐湖环境演化的气候环境代用指标研究、盐湖沉积反映的环境演化过程研究、现代盐湖动态演化过程研究等方面进行分析。进一步探讨今后青藏高原盐湖沉积与环境演化研究的主要内容,包括更为精准的测年方法及盐湖沉积高分辨率年代序列的建立、古气候环境代用指标的综合运用与新指标探究、代用指标与气候要素关系的定量研究、盐湖沉积与环境演化的区域对比及驱动机制研究、青藏高原盐湖信息数据库平台与全球变化研究。

This paper comprehensively analyzed the main research results for saline sediments and environmental evolution on the Tibet Plateau in recent 20 years, putting its focus on the chronology of saline sediments, palaeoclimatic indexes, the sedimenta- ry evolution process of salt lakes, modern saline dynamic evolutionary process and so on. It also discussed the main contents of research on saline sediments and environmental evolution on the Tibet Plateau in the future, for example, to obtain more accu- rate dating methods and establish high-resolution age sequence of saline sediments, study new palaeoclimatic indexes and the comprehensive use of proxy indexes, conduct quantitative research between proxy indexes and climate factors, study regional comparison and driving mechanism of saline sediments and environmental evolution, and study saline information database plat- form and global change.
