| 摘 要： | 对近几十年来喜马拉雅山地区冰川变化的研究成果进行了综述,可以看出:气温普遍升高、冰川加剧退缩和冰川湖泊扩大是喜马拉雅山地区气候和冰川变化的主要特征和后果.冰川退缩导致冰川灾害的危险性增加并对本地区河流径流和水资源产生较长远的影响.但各段的气候、冰川变化及其影响存在区域差异,还需要对冰川变化和水资源影响方面的预估进行更广泛和深入的研究.

| Abstract: | Some study results on the Himalayan glacier fluctuations in the last few decades were reviewed in this paper. Widely air temperature rising,precipitation decreasing,glaciers retreating and glacier lakes enlarging are the main features of Himalayan climate change and glacier fluctuations. In the middle section the Himalayas,among 23 glaciers,an average of -7.0 m5a-1 changes were observed for the last several decades. In the east part of the Himalayas,Gangri Gabu region,at least 60% glaciers are retreating si... |
