摘要	Grain size and magnetic susceptibility measurements on samples from a typical loess-palaeosol sequence on the central Chinese Loess Plateau are used to reconstruct the Pleistocene East Asian monsoon climate. The coarse-grained fraction, i.e. the weight percentage > 30 mu m of the bulk grain-size distribution, is used as a sensitive proxy index of the East Asia winter monsoon strength. On the basis of an absolute time-scale, time-series variations of this proxy show that winter monsoon strengths varied on millennial time-scales during the periods 145-165, 240-280, 320-350, 390-440, 600-640, 860-890, 900-930 and 1330-1400 kyr BP. The wavelength of these climatic oscillations varied between 1.89 and 4.0 kyr, as is shown by spectral analysis using the multitaper method. Although numerical simulation experiments show that high frequencies also can arise from measurement errors in the grain-size analysis, the frequencies prove to be sufficiently stable when the spectral analysis is repeated with a different number of tapers. For the time being, we do not correlate these climatic oscillations with palaeoclimatic records in the North Atlantic deep-sea sediments because both time-scales need to be further improved. Our data, however, certainly demonstrate that millennial-scale East Asian winter monsoon variations in the last 1.4 million years can be detected from terrestrial loess records.
