The time sequence of palaeoclimatic change from 245.20ka BP to 147.90ka BP has been established by the dating ages of the high precision TIMSU series and the analysis of the oxygen isotopes from the stalagmites of Shuinan Cave in Guilin area  The paper also confirms that the boundary ages between stage C and stage B and those between stage B and stage A are 1926±3.9 ka BP(corresponding to the deep sea core oxygen isotope stage 6 and 7),242.5±6.4 ka BP(corresponding to the deep  sea core oxygen isotope stage 7 and stage8) respectively,which is gotten by using TIMSU series dating age at 86.5 cm on the stalagmite section and depositional cycles of the stalagmite section and the sudden change characteristics The result indicates that the paleoclimate (or paleomonsoon) change reflected by the cold and warm events of the stalagmite records during 245.20 ka BP and 147.9 ka BP  can be divided into three stages:(1)the period from 245.20 ka BP to 242.6 ka BP corresponding to the last stage of the deepsea core oxygen isotope(SPECMAP curve) stage 8 ; (2) the penultimate interglacial period from 242.5 ka BP to 192.6 ka BP corresponding to stage 7 of the SPECMAP curve;(3)the penultimate glacial period from 192.6 ka BP to 147.9 ka BP corresponding to stage 6 of the SPECMAP curveThe records of TIMSU series dating ages and stable isotopes from the stalagmite reveals that the evolution history of the East Asian monsoon from 242.6 ka BPto 147.9 ka BP occurred in Guilin area corresponded well with the paleoclimate and paleomosoon changes revealed by the records of the deepsea core oxygen isotope stage 6 and stage 7, sporepollen combination,CaCO3 content from the deepsea core records and loess and paleosol from the North China,and by sea level rise and fall,soil forming,complete iron accumulation degree of loess and paleosol, magnetization rate change and the original crumb CaCO3  content and eluviation intension from the North China and so on These characteristics show that the paleoclimate evolution since the late stage of the Middle Pleistocene Epoch in Guilin area not only has the global characteristics but also has the strong regional characteristics
