THE SEQUENCE OF PALEOENVIRONMENTAL CHANGES SINCE ABOUT 4KA B. P., RECORDED BY NIYA SECTION IN SOUTHERN MARGIN OF TARIM BASIN

ZHONG Wei; XIONG Hei-gang; TASHPOLAT Tiyip; SHU Qiang

Through synthetic researches of multi-index geological records of Niya section, which are of high resolution in southern margin of Tarim Basin, this paper has reconstructed the sequences of paleoclimate in this region during historical times (since about 4000a B. P.). During the last 4000 year, the area has experienced alternations of relative cold-moisture and relative warm-dry periods. Three evident cold-moisture periods and three warm-dry periods are identifing. The study shows that the human activities have an intimate relation with the evolution of paleoclimate in the southem Xinjiang. Paleoclimate has played very important role in influencing human being's agricultural activities.
