The lake records have proved their value by providing improtant insights into how global and regional climatic events influence continental ecosystems upon which humanity is most immediately dependent.Long recored from single sites have the advantage of minimizing the effect of non-climatic variables on the cycle-to-cycle palaeoclimate study of climate proxies.The comparative study of the long core records iocated at different regions in China can provide some significant in-formation about the regiona1 differentiation of environmental evolution, and furthermore, about the Asia monsoon activities with the study on Loess plateau.However.detailed lacustrine cores studied with a span of several 1000OOa are very rare in China The available examples are only three long cor from the Zoige Basin in eastern Tibet (Qinghai-Xizang)plateau, Qaidam basin in northern Tibet plateau and Dianchi basin in Yunnan plateau respectively.The result has shown that there distinctively exist 3 stages since Mid-Pleis-toce ne, i.e.780-48OkaBP, 480-160kaBP, 160-OkaBP for each of them the enviro nment was of different and special characteristiea in different regions of China.The result has also shown that the Tibet plateau has played a major role on the differentiation process.The comparison study is still in its infancy and m ore long cores are needed for us to probe into the uplifting of Tibet plateau and As Jan monsoon evolution.
