| 摘 要： | Introduction High mountain ecosystems are comparatively thrilling and sensitive at least at the upper elevation levels, and are determined by abiotic climate related ecological factors. Therefore, the ecosystems at the low temperature limits of plant life are generally considered to be particularly sensitive to climate changes (Koerner 1999). As temperature is a key factor for high mountain plants (Koerner and Larcher 1988, Gottfried et al. 1998), an upward migration of species must be conse…

| Abstract: | Current vegetation patterns, biodiversity and adaptation of plants were studied during 1998–2001 in glacial landscape of Chaurabari
situated above Kedarnath (30° 44′ N– 79° 07′ E; 3,000– 6,000 m) in Central Himalaya. Landscape was identified into different
zones on account of the vegetation status, glacial features, geomorphology and altitudes. Cold environment with heavy snowfall,
frost hailstorm and dense frost characterizes the study area. Predominance of the soda rich feldspars indicates soda enrichment;
orthoclase, microcline weathering and alternation would have contributed potash to the soil. The increasing severity of the
environment as we ascend from timberline to snowline leads to progressive decline in the abundance and diversity of the plant
species. The diversity of the higher plants decrease, while the diversity of microflora increase from alpine zone to snowline
zone. Highly opulent and diverse flora with beautiful, delicate herbs occupy the alpine zone, but some specialized groups
of the plants, particularly high energetic and cold resistant species reside in glacial environment. Asteraceae, Rananculaceae,
Primulaceae, Rosaceae, Apiaceae and Ericaceae are the pioneer angiospermic families, whileAnaphalis triplinervis, A. royleana, Androsacce sarmentosa, Cotoneaster rotundifolius, Lonicera myrtillus, Cassiope fastigiata,
Gaultheria trichophylla andErigeron multiradiatus are the pioneer species, which have invaded in glacial environment. Through its nature, alpine glacial ecotone can be seen
easily due to environmental and edaphic differences. |
