项目摘要

The Quatemary environmental and dimatic conditions in the Near East are of academic interest, and also significant for its present-day socioeconomic development. Late Pleistocene and Holocene records will be investigated to improve the knowledge with respect to the range of the environmental and dimatic fluctuations in the Near East. Environmental and climatic conditions especially during the warmer periods of the Quaternary may be regarded as potential analogies for future climate change in a region which already faces enormous problems in water supply and sustainable use of water resources. Existing and newly developed tools for quantitative palaeoenvironmental and palaeoclimate reconstructions will be applied based on modern calibration data sets and multivariate statistical analysis. In addition, archaeological excavation sites of early, middle and late Pleistocene age will be investigated in the Jordan Valley which served as a migration corridor during the spread of hominins Out of Africa. The large number of archaeological finds from excavations is in clear contrast to the rare information available thus far with respect to the overall environmental setting and the climate conditions during the migration waves and the emergence of modern people. New information concerning the natural background during these periods will be provided as a result of the proposed research.

近东地区的自然环境和气候条件不仅具有学术意义，而且对当今的社会经济发展具有重要意义。将调查晚更新世和全新世的记录，以提高对近东环境和气候波动范围的认识。环境和气候条件，特别是在温暖的第四纪时期可能被视为未来气候变化的潜在类比，在一个地区已经面临着巨大的问题，供水和水资源的可持续利用。现有的和新开发的定量古环境和古气候重建工具将应用现代校准数据集和多元统计分析的基础上。此外，还将对约旦河谷的早、中、晚更新世考古发掘遗址进行调查，约旦河谷在人类走出非洲的过程中充当了迁徙走廊。考古发掘的大量发现与迄今为止关于移民浪潮和现代人出现期间的总体环境和气候条件的罕见信息形成鲜明对比。由于拟议的研究，将提供有关这些时期自然背景的新信息。
