The Southern Ocean(SO) is a key place, which plays an important role in global climate change. To discuss the changes of sea surface temperature (SST) in different areas around the SO,and their responding to climate evolution during the last 800 ka, the different U37k'-SST records of Ocean Drilling Program (ODP) Site 1090,ODP site 1170 and site MD962077 around the SO had been compared, and the relationships had been discussed between SST records and other climate change proxies(such as the content of Atmospheric carbon dioxide(CO_2),deltaD record in the ice core, benthic delta~(13)C value (delta~(18)OB),and so on.). Here, the result shows that : (1) the evolutions of different SST records have clearly local characteristics during the last 800 ka. During MIS(Marine Isotope Stage) 12~10,the changes of SST records between ODP site 1090 in the Southern Atlantic Ocean(SAO) and ODP site 1170 in South Tasman Sea(STS) had undergone contrary evolution trends. In detail, the glacial minimum SST value in ODP site 1090 had increased about 3.8 ℃ , and the glacial minimum value of SST in ODP site 1170 had decreased about 1.3 ℃ , contrarily. Otherwise, the glacial minimum value of SST became about 2.2°C higher after MIS 10 in site MD962077. Otherwise, all the three SST records well responding to the Mid-Pleistocene transition (MPT) event basing on the filtering and wavelet analysis results. (2) Before the Mid-Brunhes event (MBE),the average and peak SST values of ODP site 1090 are always lower than those in ODP site 1170. Nevertheless, the average and peak SST values of ODP site 1090 become higher than those in ODP site 1170 during the occurrence of MBE and MIS 5, MIS 2 and MIS 1. On the other hand, the record of ∆SST_(1090-1170) and other four proxies, such as C02, LR04-delta~(18)OB , Fe flux, and 8D, had well coherencies during the interglacial stages than those in glacial stages during the last 800 ka. The correlation coefficient are about 0.80,0.72,0.69,and 0.75,respectively. Hence, we concluded that the migrating range of STF and strength change of Agulhas leakage maybe the principal factors that influenced the change of ∆SST_(1090-1170). Meanwhile, the change of ∆SST_(1090-1170) responding to the evolution of climate is observably during interglacial stages than those in glacial stages. It has shown that the change of solar insolation and following regional climate change,such as the moving of sea fronts,which might be one major reason for the changes of ∆SST among different seas around the SO during the last 800 ka.
