Vegetationsmosaik und Florenelemente an der Waldsteppengrenze im Chentej-Gebirge in der Mongolei. (Vegetation mosaic and floristic elements on the zonal forest-steppe-border in the Chentej mountains in Mongolia)
The Southern part of Chentej mountains (Mongolia) is situated in the zonal border between the Siberian coniferous forest region and the central Asian steppe and desert region. The forest-steppe transition area is characterized by a very closed
mosaic of contrasting vegetation types and corresponding floristic elements. The contribution is based on results of biological oriented expeditions (Mongolia-GDR) since 1962. (HSC).
of a single catchment, the AA. analysed a 12.08 m sediment core from Daihai Lake in Inner Mongolia. Dating control was provided by Pb 210, Cs 137 and AMS C 14. The Rb/Sr ratios of the Holocene lake sediments are interpreted to be the direct results of changes

with high stands of other lakes in Western Mongolia. Relics of a lake sediment on top of an old dune 17 m above the floodplain have been OSL-dated,indicative of an Eemian age. At that time a large and deep lake must have covered the plain. The transition
Recent intensive grazing in Mongolia may be significantly reducing the infiltration rate of rangeland. This study measured infiltration rates using simulated rainfall with high raindrop impact for small plots established on steppe grassland, desert
grassland, and shrubland sites in Mongolia. The response of the infiltration rate to short-term livestock removal was also investigated. The results suggest that the high infiltration rate on the ungrazed plot was maintained mainly by the recovery of surface

Using a dataset up to 49 years long (1954–2002) at Toudaoguai station, this paper provides insight into the characteristics of suspended sediment transport in the Ningxia-Inner Mongolia reaches of the upper Yellow River, at different temporal scales
and sediment rating curves for different seasons have different characters. The diversiform C–Q loops in the Inner Mongolia reaches of the upper Yellow River may be mainly caused by the sediment inputs from tributaries, the different propagation velocity

The first record of stable isotopes through a complete sequence of ice within an open-system pingo in northwestern Mongolia indicates a complex history of ice formation and pingo growth. A continuous section of ice 32 m long was cored through
Quartz grains taken from Pleistocene sands and a palaeo-active layer in Poland (Łódź Teofilów) and from silty-clayey sediments of the contemporary active layer near Ulaanbaatar (Mongolia) were analysed using a scanning electron microscope (SEM
Holocene geomorphological processes and soil development as indicator for environmental change around Karakorum, Upper Orkhon Valley (Central Mongolia)
the recent town of Kharkhorin, Central Mongolia. A holistic approach involving the use of high spatial resolution geomorphological mapping, sedimentological and geochemical analysis, palynology, and geochronology shows several phases of landscape activity
