[Method] Based on data about meteorological disasters over the past 50 years and their direct economic losses dur- ing 2003-2011 in Ningxia, effects of major meteorological disasters on national economic construction as well as people＇s lives and property were discussed, and some defense countermeasures of meteorological disasters were put forward. [ Result] In Ningxia, drought, rainstorm and flood, gale and dust, hail and thunderstorm had done considerable harm to national economic construction as well as people＇s lives and property. Since 2003, total direct economic losses caused by all meteorological disasters in Ningxia changed from 1.28 billion to 1.97 billion yuan and accounted for 0.8% -3.1% of GDP of Ningxia. Among them, the direct economic losses caused by drought were the highest and annual average value during 2003 -2011 reached 1.22 billion yuan, accounting for 77.6% of total direct economic losses caused by all meteorological disasters in Ningxia. The direct economic losses caused by rainstorm, flood and hail ranked second, and their annual average values were 0.11 billion and 0.12 billion yuan, accounting for 7.4% and 7.6% of total direct economic losses. Meanwhile, annual average direct economic losses caused by thunderstorm in Ningxia reached 1.18 million yuan. In addition, annual average value of the direct economic losses caused by gale and dust totaled 0.01 billion yuan, with a proportion of 1.0%. [ Conclusion] The research could provide scientific references for the defense of meteorological disasters in future.展开更多

Three-dimensional （3D） Bi2WO6 microsphere was synthesized by the hydrothermal method using Bi（NO3）3 and Na2WO4 as raw materials. This structure exhibits high photocatalytic activity for the dyes, toxic organic compounds. The degradation of methlyene blue is 100% in 30 min, 4-nitrylphenol is 95% in 60min and p-nitrylphenol is 95% in 75min in ultraviolet （UV） light irradiation. 3D Bi2WO6 microsphere is also a good photocatalyst to treat the printing and dyeing sewage, and exhibits high repeatability. After being used the 20th time, Bi2WO6 still has high activity to degrade the printing and dyeing sewage, which is very important for a photocatalyst to be used in industry. This study will pave a new way to treat industry wastewater.展开更多
