辽西朝阳地区自然气象灾害与防御对策

Natural Meteorological Disasters and Defensive Countermeasure in Liaoxi Chaoyang District

［目的］掌握该地区气象灾害规律及防御对策，对预防、减轻气象灾害的危害程度有着极其重要的意义。［方法］ 采用常规数理统计方法，进行分析评价气象灾害与经济损失程度。［结果］ 朝阳自然气象灾害主要有6种，它们不是孤立存在的，从经济损失程度和频次可排列为：干旱、冰雹、雷电、大风、低温霜冻、暴雨。在55年中，给朝阳地区造成了70亿～80亿元的经济损失。［结论］可持续性防御自然气象灾害是防灾的基础，生态环境持续朝着良性发展是防灾的途径，改变救灾为防御的意识形态是防灾的根本。做好防御工作，气象要先行，严密监测、准确预报、及时预警，才能将灾情损失下降或解除。

[ Objective I To master the law of meteorological disasters in the region and defensive countermeasures,which had an extremely important significance to the prevention and mitigation of meteorological disasters damage. [ Method ] Evaluation of meteorological disasters and the extent of economic losses were analyzed by the methods of conventional mathematical statistics.[Result] Natural meteorological weather in Chaoyang had six kinds of major disasters, which were not existed in isolation. They can be arranged as follows at the aspects of economic losses and the frequency： Drought-Hail-Lightning-Wind-Low-temperature frost-Rain. In 55A,the Chaoyang region lost 7 - 8 billion. [ Conclusion] The sustainability of the natural meteorological disasters prevention were the foundation of disaster prevention, the ecological environment sustainable development was a healthy way of disaster prevention, changed ideology from disaster relief to defense were the fundamental of disaster prevention. Do a good job in defensive work, weather should be first, closely monitored, accurate forecasting, timely early warning ,disaster losses can be decreased or discharged.
