摘要

尼泊尔已经感受到气候变化的不利影响，尽管它对全球温室气体的贡献微不足道。许多科学家表示担心，高海拔地区气温的普遍上升对尼泊尔的环境和人道主义构成了严重的威胁，因为许多冰川和冰川湖位于喜马拉雅山脉的高处。在这项研究中，我观察了琅塘流域的温度上升，并比较了高海拔和低海拔温度的比例上升，因为这将对该地区的冰川和冰湖产生严重影响。同时，对水流进行了时间序列观测，发现琅塘流域河水流量呈下降趋势。鉴于这些发现，尼泊尔可能面临着日益严重的水资源短缺，同时也要更加认真地关注冰川融化。DOI: http://dx.doi.org/10.3126/hn.v15i0.11289 HYDRO Nepal Journal Journal of Water, Energy and Environment卷:15,2014年7月页:30-36

Impacts of Climate Change as Evident in the Langtang Catchment

Nepal has felt the adverse impact of climate change even though its contribution to global greenhouse gases (GHGs) is negligible. Many scientists have expressed concern that the general rise in temperatures at high altitudes poses a serious environmental and humanitarian threat in Nepal as many glaciers and glacial lakes are located in the high Himalayas. For this study, I have observed rising temperatures in the Langtang catchment and compared the proportional rise of high altitude and low altitude temperatures as these will have serious implications for glaciers and glacial lakes in the region. As well, conducted a time series observation of water flow and noted that the river flow in the Langtang catchment are decreasing. Given these findings, Nepal may be facing increasing water scarcity while also keeping more serious watch on glacial melt.
