雷电是一种对自然环境和社会经济都会造成很大影响的自然现象。对其进行有效的监测、预测和研究具有十分重要的社会、经济与科学价值。目前我国在雷电监测、预测和研究方面还比较薄弱，特别是在监测领域，与发达国家有较大差距。文章对雷电产生的原因及影响做了介绍，对国内外目前的探测技术及发展方向进行了分析，提出了国家雷电监测网建设应注意的问题和建议。

Lightning is a natural phenomenon that seriously affects the natural environment and human activities. Therefore, it is of important social, economical and scientific value to detect the lightning effectively. Comparing with the developed countries, China has some gaps in the fields of lightning studying, forecasting and detecting. In this article, the mechanism of lightning and its influence are described. The present situation and the direction of lightning detecting technology at home and abroad are also analyzed. Several suggestions and issues have been proposed for constructing the national lightning detecting network.
