摘　　要： 通过对尼雅剖面多环境替代指标的研究,结合塔里木盆地相关剖面的研究成果,重建了塔里木盆地近4.0kaB.P.以未的气候环境演变过程与特征,研究揭示,近4.0kaB.P以来塔里木盆地的气候环境经历了多次的干湿变迁;同时通过有关塔里木盆地的历史文献记载和考古发掘资料,恢复了历史时期以来塔里木盆地的古人类文明的兴衰变迁,并将气候环境的演变过程与古人类文明的兴衰阶段进行了对照研究,研究发现历史时期以来塔里木盆地的气候环境与人文历史之间具有很好的耦合关系:在气候的相对湿润期,环境条件适宜,有利于人类活动,使农牧业生产繁盛,人类活动范围扩大;在暖干的环境条件下,由于水份的减少,则会抑制人类的活动,导致农业歉收,人类的生存环境和条件恶化,古城废弃。 According to the synthetic study on variety of climatic and environmental proxies in Niya section, and the results of other sections in Tarim basin, we reconstructed the characteristics of paleo-climatic and paleoenvironmental evolution in Tarim basin since about 4.0kaB. P. . Since the last 4 000 years, the area of Tarim basin has experienced alternations of relative cold-moisture and warm-dry: 4.0kaB. P. -3.45kaB. P. , and the climate was generously inclined to be moisture with the passable water condition. There was the tendency of drought at the later stage: 3.45kaB. P. -2.50kaB. P. , temperature rose, and the climate became dry. It appeared to be the characteristics of warm-dry climate in 2.50 kaB. P. -1.90kaB. P. , and it was cold-moisture with good water condition, which was beneficial to the growth of crops. During 1.90kaB. P. -1.40kaB. P. , relative warm-dry in climate, the conditions of the climate and environment relatively worsen. During 1.40kaB. P. -l.OOkaB. P. , temperature descent, and precipitation increased. There was a good combination of water and heat. Duringl.OOkaB. P. -0, it was dry in climate mainly, with several cold-warm fluctuations. In the paper, we also renewed the changes of man history on the base of history documents and archaeological excavation. Through the contrast between the paleoenvironmental evolution and the changes of man history, we can find that paleoenvironmental evolution coincide with the changes of man history greatly. In the relative humid term, the environment was in order and was adapted to the human activities, and the agriculture and the stockbreeding became more prosperity. But in the dry and warm term, because of reducing of moisture, the human activities were inhibited, so the agriculture were poor harvest; the environment and conditions of human survival worsened; the old casttes were deserted.
