The Lijiagang Xiashu profile in Nanjing is a unique area for Quaternary research.Samples were taken from the file with an interval of 5 cm for measuring geochemical proxy,brightness,color reflector,magnetic susceptibility and granularity.And the climate stratum during 20～120 ka BP was divided into 5 strata of loess and 5 strata of paleosol by comparison of its multi-climate proxies with other records,such as high resolution oxygen isotopic records of marine and Guliya ice core,magnetic susceptibility of Malan loess.Luminescence dating technique was also adopted in this study,distinguishing 4 climatic cycles,corresponding to the MIS2～MIS5.And the stage corresponding to MIS3 was especially warm and wet,demonstrating its significant difference from the Tibet Plateau and the loess in West China in process and intensity of the climatic change.It’s indicated that the ocean warming plays an important role on the East Asian monsoon area.
