Global change is one of the key problems that human faces, and the understanding on the past global change, especially on the paleoclimatic change up to 200 000 a BP, is the key to forecasting future climatic change. Based on the studies on the loess, the lake deposits, the ice cores, the marine sediments and the cave sediments, some important results have been got in China. But there are still so medeficiency, i. e. low resolution records, lack of systematical information in some areas and comprehensive mechanism studies etc. Considering these deficiency and the special regional superiority in China, we should give more effective studies on some important areas and periods in order to understand further the influence of the uplift of Qinghai-Xizang plateau on the East Asia's climate, the evolution of the East Asia monsoon and so on.
