Abstract

The analysis of tree-ring data of Siver fir (Abies pindrow [Royale] Spach.) and Himalayan pine (Pinus wallichiana A.B. Jackson) from the sub-alpine forest from Gangotri glacier region, Northwestern Himalayan signifies the importance of AugustSeptember temperature in controlling the growth of these trees. Mean temperature in each year for these two months has been reconstructed from A.D. 1995 up to A.D. 1773 based on ring-width and density data. The calibration model explains 44% variance in the instrumental data (1902-1987). The reconstructed temperature series shows annual to multiyear fluctuations punctuated with

基于树木年轮数据的喜马拉雅西北高海拔地区气候变化分析。

对喜玛拉雅西北部甘戈特里冰川地区亚高山森林中银杉(Abies pindrow [Royale] Spach.)和喜玛拉雅松(Pinus wallichiana A.B. Jackson)树木年轮数据的分析表明，8 - 9月的温度对这些树木的生长具有重要的控制作用。根据环宽和密度数据，重建了这两个月从公元1995年到公元1773年的年平均气温。校准模型解释了仪器数据(1902-1987)中44%的方差。重建的温度序列显示出年至多年的波动

期刊介绍： The "Journal of Himalayan Earth Sciences" (JHES) is a biannual journal, managed by the National Centre of Excellence in Geology, University of Peshawar, Pakistan. JHES is recognized by Higher Education Commission (HEC), Pakistan in "X" Category. The JHES entertains research articles relevant to the field of geosciences. Typical geoscience-related topics include sedimentary geology, igneous, and metamorphic geology and geochemistry, geographical information system/remote sensing related to natural hazards, and geo-environmental issues and earth quake seismology, and engineering and exploration geophysics. However, as the journal name implies, the articles addressing research relevant to the above disciplines in the Himalayan region will be given prime importance and relevance.
