武夷山生态站试验地的地形地质特点为山势陡峭、表土薄、下层为砾石、土壤电阻率高,因此用于野外连续监测的仪器容易遭受雷电袭击,鉴于此本研究采用以隔离为主,分散、疏泄、入地为辅,多级阻隔消减、逐级衰减雷电感应过电压的防雷方案保护野外仪器,阐述了该方案的工作原理,并对其应用环境及其局限性进行了分析和讨论,以期为我国森林生态定位站野外监测仪器的防雷安置提供借鉴。 The topography and geology characteristics of Wuyishan Ecological Station are steep mountains, thin topsoil and gravel in the lower layer. The soil resistivity is high, therefore, the instruments used for field continuous monitoring are easily attacked by lightning. In view of this, , Catharsis, earthing supplements, multi-level barrier abatement, step-by-step attenuation of lightning induced over-voltage lightning protection program to protect field equipment, described the working principle of the program, and its application environment and its limitations were analyzed and Discussion, in order to provide reference for the lightning protection of field monitoring instruments in forest ecological locating station in our country.
