| 英文摘要 | Natural archives like ice cores, tree rings, river and lake sediments, lake terraces, and paleosols and also historical documents witness aspects of climate change in northwestern China during the Western and Eastern Han Dynasties (206 B. C.-220 A. D.). Reconstructions of decadal averages of annual mean temperature and precipitation fluctuations were derived from variations of delta(18)O and net accumulation rates in the Guliya ice core. They revealed a period of higher temperatures and higher precipitation than today, which affected vast areas of northwestern China during the period of interest until the fifth century A. D. These conditions resulted in a marked increase in the discharge of big endorheic river systems, such as the Tarim, the Keriya and the Manas rivers. As a consequence, water levels in appendant terminal lakes rose, e. g., at Lop Nor, Manas Lake, and Baijian Hu. Lake surface areas expanded, and lake desalting occurred also at lakes in intermontane basins, such as Balikun Hu and Qinghai Lake. The warm and moist conditions during the Western and Eastern Han Dynasties might have been responsible for the large-scale agricultural production and the local socioeconomic boom that is documented by the occurrence of the famous ruin groups of Loulan, Niya, and Keriya. The following desiccation phase led to a deterioration of water resources, and most oases tended to dry out and were finally abandoned. The appearance, development, flourishing, and final abandonment of each great ruin group are closely associated with regional climate change at that time. |
