Climate cooling and glacier advance during the late Holocene are discussed with case studies from the Causasus, Pamiro-Alai, Tien Shan, Altai, Sayan, Polar Urals, mountains of Yakutia, and Kamtchatka. Palynological and geomorphological data yield

Rational utilization of mountain soils in southeast Qinghai-Xizang (Tibetan) Plateau
Afforestation ; China ; Deforestation ; Ecology ; Forest soil ; Land use ; Mountain ; Pastureland ; Qinghai ; Resource management ; Slope gradient ; Soil ; Tibet
The southeast Qinghai-Xizang (Tibetan) Plateau is a physical region with optimum hydrothermal conditions, alpine soils and most types of Chinese forest soils. At present, partial soil resources are being damaged and the mountain ecology also tends
to be instable. So rational cutting and forest conservation, barren mountain afforestation, returning the cultivated land on steep slopes to forest, controlled grazing, and soil amelioration constitute important means for rational use of soil resources
and improvement and stabilization of mountain ecology in this region.

This paper deals with the mountain front alluvial fans in the semi-arid areas of Murcia and Almeria provinces. It attempts, by mapping the location of alluvial fans, then their classification into aggrading or dissecting fans, to identify the extent
to which the mountain fluvial systems are buffered by aggrading alluvial fans or exhibit channel continuity through the mountain front environment. It further considers the implications of climatically induced changes between aggradational and dissectional
This study examines post-glacial hillslope incision and its controlling factors for 3 mountainous regions in Japan. First, data were analyzed for each region, then the results from different regions were compared.
Late Quaternary hillslope erosion rates in Japanese mountains estimated from landform classification and morphometry

This paper presents a method for estimating long-term hillslope erosion rates in rugged mountains, based on landform classification and morphometry. Firstly, the average slope lowering rates in the basins since the Late Glacial are estimated based
Application of relative-age dating techniques on rock glaciers of the La Sal Mountains, Utah: an interpretation of Holocene paleoclimates

Relative ages of rock glaciers and talus of the La Sal Mountains, Utah, were determined using several techniques: lichenometry, Schmidt-hammer rebound value, clast roundness, clast surface roughness, and weathering rind thickness. The techniques

Mutual Climatic Range (MCR) analysis was applied to 20 fossil beetle assemblages from 11 sites dating from 14,500 to 400 yr B.P. The fossil sites represent a transect of the Rocky Mountain region from northern Montana to central Colorado
Debris-flow magnitude-frequency relationships for mountainous regions of Central and Northwest Europe

From the viewpoint of hazard assessment the magnitude-frequency characteristics is an essential element of the debris-flow process. For this study, published data specifying both magnitude and frequency were used for the Alps, the Tatra Mountains
, Scotland, Norway, and Swedish Lapland in addition to material for the French Alps. Activity levels within Northwest European mountains were found to be lower than in the Alps or the Tatras. Possible explanations are discussed, in which precipitation
