Extended data
Major academic achievements of Academician Li Jijun;
1. The rising stage, rising range and rising form of the Qinghai-Tibet Plateau are put forward.
It is the first time at home and abroad to systematically and comprehensively put forward the rising stage, rising range and rising form of the Qinghai-Tibet Plateau. 1979 points out that the whole fault block of the plateau accelerated to rise by 3500-4000m in Quaternary, which had great influence in academic circles. Later, it was pointed out that the Qinghai-Tibet Plateau had strong movements 3.6 million years ago, 240 million years ago and10.6 million years ago.
It is believed that about 2.4 million years ago, the altitude of the plateau exceeded 2,000 m, which led to the modern East Asian monsoon, and a large amount of loess accumulated in the middle reaches of the Yellow River, forming the famous Loess Plateau. It is pointed out that the Yellow River is the product of the uplift of the Qinghai-Tibet Plateau. With the intermittent rise of the plateau, the Yellow River has produced traceable erosion and corresponding undercutting.
It is pointed out that the Yellow River and Jinsha River in Lanzhou were connected after 6.5438+0.6 million years ago, and the multi-stage terraces formed in the upper reaches of the Yellow River 654.38+0.6, 654.38+0.5, 654.38+0.2, 0.6 and 0.654.38+0.5 million years ago reflected the stage of plateau uplift. The ages of the above sections of the Yellow River in Lanzhou have gradually changed, corresponding to the specific terraces in Lanzhou.
2. The modern glaciers and Quaternary glaciers in Tibet are systematically studied.
In particular, he has a new view on monsoon marine glaciers, and edited Tibet Glacier and Hengduan Mountain Glacier. It is pointed out for the first time that there are a lot of hot and humid landforms and some cold debris flow landforms in Lushan Mountain, which has replaced the explanation of the origin of glaciers and generally clarified the ancient glacier dispute that has puzzled geologists in China for half a century.
