摘要
云贵高原有着独特的地理环境 ,其气候变迁应与青藏高原这一特殊的高海拔、低纬度的隆升地块有重要关系。洞穴化学沉积物是响应环境变化的地质记录档案 ,通过对它蕴藏的古气候信息的解译 ,可以反演过去的气候变化。本文侧重介绍了洞穴次生化学沉积物研究近年来取得的最新成果及其研究现状 ,并利用其在古环境研究中的优点 ,来讨论青藏高原的抬升对西南地区环境变化产生的屏蔽效应的可能性。
The Yunnan\|Guizhou area, a special high\|altitude, low\|latitude ascending block, whose climate change may have much important relationship with the Qinghai\|Xizang Plateau, has a special geographical environment. Cave sediment is a good geological recorder of environment change. In this paper we mainly introduce the latest progresses in cave sediment research, and discuss the possibility to demonstrate the screen effect of the Qinghai\|Xizang plateau's uplifting on the environmental change of Southwest China by means of extracting paleo\|information from the cave sediments.\;
