青藏高原气候变化和人类活动共同作用导致青藏高原冰川退化,与冰川有关的灾害风险与日俱增.通过对林芝、那曲、乃东三县域的问卷调查和实地考察,分析了青藏高原典型县域冰川退化的现状、成因及对自然环境和社会经济的影响,并针对当地的适应对策和居民的适应能力情况,提出当地应对冰川退化的对策建议.结果表明:青藏高原典型县域的居民适应力相对较强,政府自发适应力较弱,社会、经济适应力相对较弱.为了适应气候变化对青藏高原冰川变化的影响,建议应当积极发挥政府的调节作用,健全管理体制及各项规章制度,加大水资源科学管理,冰川退化的防护基础设施建设,加强宣传教育力度.
The Adaptation Countermeasures to Glacier Shrinkage in Some Typical Counties of Tibetan Autonomous Region
The climate changes and the human activities have caused the glacier shrinkage in the Tibetan Plateau. The glacier-related disasters are increasing day by day. The three typical counties in Tibetan Autonomous Region have been selected to examine based on some questionnaires and in-situ investigation. According to the findings, the adaptabilities of local residents to the glacier shrinkage are as follows: the resident's adaptabilities are relatively well, the government's self-adaptation is poor, and the social and economic adaptation is relatively poor. The current adaptation situations are as follows: the effects of eco-protection policies are good; the industrial structure is unreasonable and the level of agricultural industrialization is low;the management system of woodland and grassland is not perfect; water resources utilization is inefficiently. In terms of the practical situations of these counties, the following countermeasures for solving the problem of glacier shrinkage are put forward: 1) to enhance the adaptability of the residents following the local government's regulation,2) to improve the management system and regulations, so that the resources and the environment will no longer be damaged, 3) to strengthen the development and utilization of water resources, 4) to speed up the construction of protective infrastructure against glacier shrinkage, and (5), last but not least, to intensify the publicity and education in order to encourage people to build up a high sense of responsibility.
