聚焦变化中的盐湖:二次科考盐湖专题阶段性研究进展

Focusing on the Changing Salt Lake: The overall Design and Implementation of the Salt Lake Project

青藏高原是我国重要的生态屏障,也是重要的盐湖分布区。在青藏高原第一次综合科考时曾对青藏高原盐湖开展过系统调查。二次科考在一次科考的基础上,加强了对一些工作程度不够的极端困难区的补充调查,还重点开展了气候变化及资源开发双重影响下青藏高原盐湖资源与环境的变化趋势;现代盐湖关键元素迁移、富集规律;古钾盐成矿预测;盐湖资源开发的生态环境效应等研究工作。经过近3年的系统工作,专题获得了大量一手科考数据,已取得了一批有显示度的科学成果。研究系统介绍了盐湖专题科考方案的整体思路、研究内容、技术路线、前期获得的亮点成果及下一步工作计划等。

The Qinghai-Tibet Plateau is known as a significant ecological barrier of China as well as an important salt lake distribution area. A systematical investigation about salt lake had been carried on during the first comprehensive scientific expedition to the Qinghai-Tibet Plateau 50 years ago. Based on previous works, the second comprehensive scientific expedition mainly focus on the supplementary investigation of the salt lakes located in some extremely remote areas, the dynamic of salt lake under the impact of climate change as well as the human intervention, the migration and enrichment rule of key strategic elements from salt lake, the metallogenic prediction of the ancient potash deposit, and the eco-environmental effect of resource utility, and so on. Through 3-year efforts, a large amount first-hand data and several encouraging outputs have been achieved. For better understanding of the whole picture, this paper introduced the framework of the project design, the research contents, the technical route,the highlight,and the plan for the second-stage investigation.
