摘要: 塔里木盆地南缘和田绿洲约特干遗址剖面多指标综合地记录到了近6.7 ka BP以来的环境变化。考虑到此地区人类活动的历史,各指标的变化记录了自6.7—4.0 ka BP期间环境变化的自然过程,揭示出6.5—6.7 ka BP期间的显著湿润期以及出现于4.0 ka BP之后的转干和3.0 ka BP前后的相对冷湿期。自2.0 ka BP开始,人类活动的影响渐趋于显著。

Abstract: A comprehensive record discovered in the Yuetegan relic site in the Hetian Oasis, southern margin of Tarim Basin, gives us a brief history of environmental change and human activities since about 6 700a BP. Taking the local human activities into consideration, the changes of various climate proxies indicated a possible natural process of environmental change during 6 700~4 000 a BP. It reflected an evident humid period occurred at about 6 700~6 500 a BP; at about 4000 a BP, climate turned into aridity; and at about 3 000 a BP, a relatively cold humid period appeared; stronger human activities started since about 2 000 a BP.

Key words: Hetian oasis, Yetegan section, mid-Holocene, environmental change, human activity
