| 摘 要： | 全球变化是当今人们所面临的重大问题之一，而对过去全球变化的认识，尤其对近20万年以来的古气候变化的认识是预测未来全球变化的关键。我国对黄土、湖泊沉积物、冰心、海洋沉积物等信息载体的研究已取得了大量的成果，但仍存在分辨率不高、研究区域分布不均、系统研究不够等问题。因此，应针对这些不足，并结合我国的特殊地域优势和气候形成机制，对一些重点地段和时间段加强研究，以便加深对青藏高原抬升对东亚气候的影响和东亚季风的演化规律等问题的认识。

| Abstract: | 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 some deficiency, 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. |
