A multi-proxy Lateglacial environmental record is described from Lake Naleng (31.10°N; 99.75°E, 4200 m above sea level), situated on south-eastern Tibetan Plateau to gain deeper insights into the hydrological and palaeoclimate development since 17.7 cal ka BP. Palynological reconstructions of variations in mean annual precipitation (MAP) and temperature (MAT), sedimentological data and sediment chemistry including weathering indicators provide a multi-faceted picture of local and regional environmental changes since the Lateglacial. Principal component analyses of all parameters provide information on interrelationships between each parameters, which help to evaluate their traceability to temperature and precipitation and to estimate their usability as proxy indicators for local and or regional variations.
