Paleoenvironment analysis of the middle reaches of Yarlung Zangbo River and Changguogou site

摘要:
西藏拉萨昌果沟遗址位于雅鲁藏布江中游支流的阶地上，是重要的新石器时代遗址。为探讨昌果沟遗址附近的古环境，对遗址附近开展地貌调查，在遗址北面约1 km处选取1个全新世风成沉积剖面进行光释光测年和环境指标分析，在雅鲁藏布江中游选2个阶地剖面进行光释光测年分析；此外，还总结了雅鲁藏布江中游23个全新世古土壤/泥炭的测年数据，进行概率密度分析，试图揭示区域的环境演化特征。研究表明：全新世古土壤/泥炭年代的概率密度可以较好地反映区域气候变化，9.0~6.0 ka古土壤/泥炭发育在波动中增强，气候由冷干向暖湿转换；6.0~2.9 ka古土壤/泥炭发育最强，气候相对温干；2.9 ka后鲜有古土壤/泥炭发育，气候变得冷干，史前人类活动受限。4.5 ka之后雅鲁藏布江中游及其支流一级阶地的形成为新石器时期先民提供农业耕作的场所，古土壤的发育为农作物提供了丰富的营养。1.4~1.1 ka期间（吐蕃王朝时期）局部地区有古土壤发育，气候好转。
Abstract:Changguogou site(3200 a B.P.), an important Neolithic site, is located in south of Lhasa(Tibet). The site is located on a terrace of the Changguogou tributary in the middle reaches of the Yarlung Zangbo River. The site and its surroundings are covered with shifting sand. In order to explore the paleoenvironment of the Changguogou site and its surrounding area, this paper carried out geomorphic investigation around the site and the valley in the middle reaches of the Yarlung Zangbo River. CGG aeolian sedimentary profile(29°21'55.2"N, 91°08'56.7"E; 3666 m a.s.l.) located ca. 1 km north of the site was selected for optically stimulated luminescence(OSL)dating and environmental proxy analysis. JDX profile(29°17'08.8"N, 91°09'13.1"E; 3570 m a.s.l.) and ZXT profile(28°59'38.3"N, 93°16'29.8"E; 3054 m a.s.l.) from terrace in the middle reaches of the Yarlung Zangbo River were selected for OSL dating. In addition, 23 dates from Holocene paleosol/peat layers in the middle reaches of the Yarlung Zangbo River were summarized, and the probability density analysis was conducted to reveal the regional climate evolution.
Our results show that, the probability density of Holocene paleosol/peat dates can well reflect regional climate change. From 9.0~6.0 ka, the development of paleosol/peat was mainly in a fluctuating growth trend, indicating that the climate turned to warm and wet; from 6.0~2.9 ka, paleosols' development reached its peak and the climate was relatively warm and dry; after 2.9 ka, the climate became drier and colder, the development of paleosols weakened and the prehistoric human activities were limited.
The OSL dating results of three profiles and environmental proxy analysis of CGG profile showed, the first terrace of the middle reaches of Yarlung Zangbo River and its tributary was formed after 4.5 ka, which could provide an ideal place for the agricultural activities of the Neolithic ancestors, and develop paleosols provided suitable nutrition for crops. Paleosol developed at some places during the Tubo Dynasty period(1.4~1.1 ka), when the climate improved.
