英文摘要	Previous studies from the central and eastern Chinese Loess Plateau (CLP) showed that the S5-1 paleosol, which corresponding to Marine Isotope Stage (MIS) 13, was the strongest developed during the last million years, suggesting extremely strong East Asian summer monsoon (EASM). However, evidence shows that regional diversity exists in the relative intensity of the S5-1 soil formation. In this study, we first verify systematically the S5-1 soil development across the whole CLP by using numerous loess records. We then examine the spatial variation of the magnetic susceptibility of different loess-paleosol sections to identify the spatial change of the EASM intensity during MIS-13. We also compare the loess records with other monsoon records in China. Our results show that, in central CLP, S5-1 is indeed the strongest developed as suggested by previous studies, whereas in the western CLP, it is weakly developed and the S4 paleosol developed during MIS-11 is the strongest. As compared to MIS-11, the northern front of the EASM during MIS-13 didn't penetrate into western CLP, but was located more northerly and eastward. Based on sea surface temperature records in the tropical Pacific, we suggest that the temporal and spatial abnormal variation of the EASM during MIS-13 could be related to a strong La Niña or La Niña-like climate condition. Under such condition, the Western Pacific Subtropical High (WPSH) becomes weaker and retreats more northeastward, leading to more precipitation in the mid-east region of northern China but less rainfall in the western inland. © 2019
