摘　　要：武当山是世界文化与自然遗产,因而武当山风景区的雷电防护尤为重要。截取风景区的地闪数据,以1km2范围为基本单元,得到各单元内2008-01-01—2011-12-31期间的全部地闪频次、极性、强度等参数,分析了武当山的雷电环境及地理环境对雷电活动的影响。研究表明:雷击大地密度整体上随高度表现出明显的增长趋势,电流强度平均值与高度大致呈现反向分布趋势。通过研究致灾环境的基本规律,进而有针对性的制定出科学合理的防护措施,对古建筑的防雷具有重要意义。Wudangshan Mountain is the World Cultural and Natural Heritage, so that lightning protection is particularly important about Wudangshan Mountain Scenic Area. The lightning frequency, polarity,intensity and other parameters in each unit from January 1,2008 to December 31,2011 are gained,with the range of 1 km2（ 1 km x 1 km） being the basic unit, for the whole area of the Wudangshan Mountain. At the same time, the influences of geological features and the lightning environment and geographical environment of the Wudangshan Mountain on light- ning activities are analyzed. Research shows that： the lightning frequency increases with increasing altitude, while the average lightning current intensity decreases in the mountainous areas. It is targeted to make scientific and rea- sonable measures by researching and analyzing the basic laws of the hazard environment, which is of great signifi- cance for lightning protection of ancient buildings.
