中文摘要	通过对河西走廊中部黄土剖面磁化率、CaCO3百分含量、色度(明度、红度、黄度)、粒度等气候代用指标的分析,初步重建了河西走廊中部全新世气候变化.发现河西走廊全新世大暖期从9 000 a BP开始,结束于2 200 aBP,期间有3次明显的气候旋回:8000～6200 aBP,5 600～4 300 aBP,3 000～2200 aBP.在此基础上,简单阐述了在中国黄土高原西部,全新世古文化对气候变化的响应,旨在说明河西走廊中部黄土剖面记录的全新世气候变化具有普遍性.
英文摘要	The study area, Minle County (37°56’19"～38°48’17"N, 100°22’59"～101°13’9"E), is located in central Hexi Corridor, Gansu Province, the Badain Juran Desert and Tengger Desert are located on its northeast and east respectively. Where the elevation varies in a range of 1589～5027m a. s. 1., it belongs to the continental desert steppe climate, the annual air temperature and precipitation are 3℃ and 400mm respectively, and the ecological environment is vulnerable and sensitive to climate change. After analyzing the substitutive climatic indexes, such as the susceptibility, percentage composition of CaCO_3, colourity (redness, lightness and yellowness) and granularity of a loess profile in central Hexi Corridor, in this paper the model of Holocene climate change in central Hexi Corridor is developed. The results show that Holocene warming stage began from 9000 a BP and ended in 2200 a BP. There were three evident climate fluctuations during the periods of 8000～6200 a BP, 5600～4300 a BP and 3000～2200 a BP. The significant temperature decrease occurred during the periods of 6200～5800 a BP and 4000～3500 a BP. The response of ancient culture to Holocene climate change in the west Loess Plateau is discussed so as to reveal the universality of Holocene climate change recorded in the loess profiles in central Hexi Corridor.
