摘要
目的分析近代西藏雪灾发生的时空特征,及其对西藏高原牧业影响的力度,为防灾减灾提供地方性经验借鉴。方法文献考证、历史分析和GIS制图。结果近代西藏有两次特大雪灾,间隔周期约为100年;西藏雪灾的地理分布集中在高原的纯牧区或农牧兼营区;土鼠年大雪灾对高原牧业破坏严重,并间接促成了《铁虎清册》的制定。结论近代西藏各级的雪灾灾后应对为适应性应对,是种理性选择,而对于未来西藏雪灾的预测预警尚需要更多学科的合作研究。
Aim To analyze the recent snowstorm in Tibet, in terms of the space-time characteristics, the influence to the livestock-raising, to provide suggestion to local disaster prevention and mitigation. Methods Literatural review, historic analysis and GIS mapping. Results Two blizzards happened in modem Tibet, whose interval peri- od is about 100 years, which involved pastoral or purely pastoral sideline area in Tibet. The livestock-raising was severely damaged by the big snowstorm in Soil Rat Year( 土鼠年), which indirectly led to the composition of "Tiehu List". Conclusion Although measures have been carried out after show calamity, they are adaptive means, so more cooperative interdisciplinary research is in high demand to forecast snowstorm in Tibet in the future.
