In this study,Hoh Xil area,hinterland of the Tibetan Plateau,was taken as the research area,tie points derived by matching the observed agnetostratigraphy were adopted to establish the geomagnetic polarity time scale ( GPTS) ,an orbital tuned timescale was developed for core BDQ06. The climate evolution in Hoh Xil since 0. 9MaBP was reconstrcted by analyzing colour,magnetic susceptibility,total organic carbon ( TOC) ,and grain size of lacustrine sediments. Evolutionary process of the climate can be divided into 5 stages: stage 5( 929 ~ 660kaBP) : alternating between warm - humid and cold - dry period; stage 4( 660 ~ 460kaBP) : climate was temperate and turned dry; stage 3( 460 ~ 360kaBP) : comparatively temperate and arid climate; stage 2( 360 ~ 160kaBP) : cold - arid and warm - moist alternated frequently; stage 1( 160 ~ 5kaBP) : alternating between warm - humid and cold - dry period. Furthermore,the climate change of our study area was compared with the LR04 marine delta18O record. The results indicated that there was very strong similarity with the scale of glacial - interglacial cycle,however there were also obvious regional differences. That is to say,our research area responded to global climate change with regional characteristics,which might be related with the tectonic uplifting of the Tibetan Plateau and had an important significance for studying regional climate change and global climate change.
