新疆沙尘暴气象灾害演变研究

Study on the Meteorology Disaster of Sand Storm Evolution in Xinjiang

新疆要快速实现社会、经济、生态可持续发展。必须提高抵御沙尘暴灾害的能力，急待了解沙尘暴灾害的演变规律。利用气象灾害历史统计资料，总结新疆沙尘暴危害的主要类型，分析1761～1949年新疆沙尘暴灾害基本特征和1961～2000年沙尘暴灾害的频次演变，得出新疆重大沙尘暴灾害呈阶段性变化。这与沙尘暴天气日数呈下降变化趋势并不具有同步性。新疆沙尘暴灾害受经济、人口、耕地等变化因素的影响大。

In order to realize Xinjiang＇ s social, economic, ecological sustainable development early, the ability resisting sand storm disaster should be enhanced, and to study the sand storm disaster＇s evolution rule urgently. Using the meteorological disaster history statistical data,the predominant type of sand storm harm in Xinjiang is summarized, Xinjiang sand storm disaster basic characteristic from 1761 to 1949 and the sand storm disaster frequency evolution from 1961 to 2000 are analyzed,and the conclusion is drawn that the mainly sand storm disaster in the area are the stepped changes, which are not synchronism with the drop tendency change of the sand storm weather in Xinjiang. The changes are influenced by other factors, such as economy, population, and cultivated land change.
