Research and Application of Evaluation Index of Meteorological Disaster Losses——A Case Study in Shaanxi Province
摘要
Abstract
In order to quantitatively assess losses caused by meteorological disasters, based on meteorological disaster data in Shaanxi Province during 1984 ～ 2007, three disaster factor indexes including the rate of death,disaster rate of crop area and direct economic loss rate are established to compute synthetic disaster condition index, then the yearly disaster loss evaluation index is established. The disaster year will be divided into five kinds: more serious, serious, in general, lighter and light. Meteorological disaster from 2008 to 2010 is evaluated by the yearly disaster loss evaluation index which is used into yearly climate impact assessment operation. Every kind of meteorological disaster factor index and synthetic disaster condition index are analyzed, the most serious meteorological disasters in Shaanxi Province are determined as rainstorm, drought, hail, continuous rain, meteorological geological disaster, etc. The results indicate that, mortality rate caused by meteorological disasters in the province shows a decreasing trend, which is 3. 23/1000000 per year. The direct economic loss is not obviously changed, with an average of 1.51％ for years, while the rate of crop area affected shows a significant increasing trend as 21.99％ per year.关键词
