| 摘 要： | 通过在宁夏地区选择3种典型的土质结构,分别设置了3种不同结构的防雷接地体,经过1年的对比观测,用回归方法来分析平均气温和土壤湿度变化对不同土壤电阻率和不同结构接地电阻的影响,说明不同土质结构在不同时间（或季节）内、不同的温湿度条件下,对土壤电阻率的影响和不同结构防雷接地体的变化特点和规律,从而提出了防雷接地体的敷设和结构性能最优要求。

| Abstract: | An observational experiment was conducted on the impact of air temperature and humidity variation on soil resistivity and earthing resistance with different structures by selecting three typical soil conditions to set three vari structure lightning protecting earthing bodies in Ningxia for one year. By means of comparative and regression analysis, the impacts of different soil conditions on soil resistivity at different temperatures and humidity in different seasons, and the variation characteristics and regularities of the lightning protecting earthing bodies with different structures are studied, and accordingly the optimal requirements for the layout and structure of lightning protecting earthing bodies are presented. |

| Keywords: | soil resistivity spatial and temporal distribution lightning protecting earthing body |
