v研究成果

主要从事巨水系发育和青藏高原隆升及其环境效应研究,主要成果总结如下:

1、在前人研究的基础上,根据较精确的测年资料,较系统地研究了黄河全程的形成历史,指出黄河形成是通过袭夺、串联内流水系进行的,先后经历了3.6Ma前、3.6-1.7 Ma1.7-1.1 Ma1.1-0.1 Ma和最近10ka等五个发育阶段,较早定量给出了黄河的形成年代,填补了黄河最上游发育研究的不足,有关研究成果完成后,受到了学术界的普遍关注。

2、根据夷平面、剥蚀面和河流阶地等资料,进一步完善了青藏高原第三纪高度变化历史和第四纪强烈隆起主要事件发生的年代,丰富了李吉均院士等关于高原隆升过程的观点。指出青藏高原在第三纪经历了两次抬升和两次夷平;导致青藏高原达到现代高度的强烈隆起开始于3.6Ma前,而后经历了多次强烈构造上升事件。3.6MaBP高原主夷平面解体前其海拔高度不超过1000m 2.5MaBP时青藏高原的高度超过2000m0.6MaBP时超过3000m0.1MaBP以后超过4000m。青藏高原隆起不仅改变了它本身的自然环境,而且对其周围乃至全球的自然环境也产生了重大影响。在青藏高原隆起研究基础上,提出青藏高原是晚新生代全球气候变化的"驱动机""放大器"

3、  通过对黄河上游和祁连山等地区河流阶地的研究,比较系统地探讨了黄河上游及其毗邻地区河流阶地的形成发育模式。指出河流阶地的形成受构造抬升和气候变化共同控制,气候的影响主要表现为决定河流下切(阶地形成)的时代,构造的影响表现为控制河流下切幅度。

4、  根据沙楔等冰缘遗迹,通过较精确的年代测定,恢复了最近15万年青藏高原多年冻土边界变化过程,提出最近两次冰期时我国的纬度多年冻土带和高原多年冻土带连成一体,青藏高原冰期气温下降幅度大于同纬度其他地区。

5、根据川西甘孜地区晚更新世黄土研究了末次间冰期以来青藏高原东部的环境和季风变化,指出甘孜地区黄土记录的气候变化与黄土高原地区存在差异,它与印度洋季风记录的对比较之与全球冰量曲线的对比更为接近,可能反映了青藏高原与印度洋季风在成因上存在内在联系或二者具有共同的驱动机制;根据兰州附近的黄土气候记录,揭示了末次冰期中季风环流的不稳定性以及其Heinrich事件和Bond周期的关系。
