Structural patterns of land types and optimal allocation of land use in Qinling Mountains
China ; Ecosystem ; Land use ; Mountain ; Remote sensing ; Shaanxi ; Soil ; Soil properties ; Sustainable development ; Thematic Mapper ; Typology
The case study based on Qinling Mountains in Shaanxi Province of China, with the information from TM image, classifies the land types and analyzes their spatial and temporal differential law, and puts forward 3 structural patterns of land types
in mountainous areas, namely, spatial, quantitative and qualitative structures of mountainous land types. After the all-around comparative analysis, an optimal allocation of land use in Qinling Mountains has been put forward according to the principle
Parameterization of incoming longwave radiation in high-mountain environments
Air temperature ; Atmospheric moisture ; Cloud ; Cloud cover ; High mountain ; Model ; Mountain ; Radiation ; Radiation balance
Some ecological applications and energy budget calculations of the earth's surface require accurate estimates of incoming longwave radiation. As cloud cover observations are not conducted frequently in high-mountain environments, a new model
radiation. The model was calibrated with data from high-mountain and lowland stations and the results are compared with existing models.
Geomorphological controls on landslide activity in the Du Toit's Kloof Western Cape mountains, South Africa
Earth surface processes ; Landslide ; Lithology ; Mountain ; Mudflow ; Slope dynamics ; South Africa ; Spatial distribution ; Western Cape
Landslide activity is known to be common in the Western Cape mountains. The important causes for slope failure were found to be lithology and break in slope angle. The spatial distribution of landslides appears to be closely related to contact
This paper provides an evolution of geomorphological surfaces effected by plate tectonic, erosion and accumulation in the Carpathian Basin. The basis of the study is a model for the geomorphologic evolution of the Transdanubian Mountains, North
Glacial valley cross-profile morphology, Tian Shan Mountains, China
The purpose of this paper is to use the power law or quadratic equations in studying the morphology of glacial valley cross-sections in the middle and western Tian Shan Mountains, to further examine the evolution patterns of glacial valley form
damages. Different natural and urban conditions in the Czech Ilysch Carpatian and crystallin Sudeten Mountains are compared and the role of geographical position discussed. - (MS)

To understand the origin of Mountain Lake in light of previous hypotheses, the AA. examine the regional and local geology of the drainage basin. Field reconnaissance was followed by structural analysis. Fracture-trace analysis reveals a regional
Landform and vegetation change in the Greaves Creek Basin : an asymmetric hanging valley in the Blue Mountains, New South Wales

Greaves Creek has cut a hanging valley through the entire Triassic sandstone sequence near Blackheath in the western Blue Mountains. The course of the creek is related to joint directions. Topographic asymmetry expressed as unequal slopes
Late Pleistocene cosmogenic Cl 36 glacial chronology of the southwestern Ahklun Mountains, Alaska
Thirty-two cosmogenic Cl 36 surface exposure ages constrain the timing of two late Pleistocene glacial advances in the western Ahklun Mountains. Boulders were sampled from one early Wisconsin (sensu lato) and six late Wisconsin moraines deposited
by ice-cap outlet glaciers and local alpine glaciers. The Cl 36 ages are consistent with limiting C 14 and thermoluminescence ages from related deposits and indicate that Ahklun Mountains glaciers reached their most extensive position of the last

The Serra da Estrala is the highest mountain massif in Portagal (40°20'N; 7°35'W; 1993 m asl) and the part of the Iberian Central Cordillera. A significant topoclimatic differenciation inffluenced the present-day landscape dynamics arises from
the original imprint that glacial erosion gave to the mountain. The study of the local climates is a major element of an integrated project for the study of landscape units, which has being conducted in the Serra da Estrala. For the first time air temperatures
will be used for the mountain rescue team, which is interested in the extreme values obtained and in the air temperature patterns and models. - (BJ)
