遵义市雷电灾害致灾因子危险性区划研究

利用遵义市14个国家气象站1978-2013年雷暴日数据和2006-2020年的ADTD雷电定位数据，叠加遵义市基础地理信息（包含县边界、水系分布等）、人口、GDP等数据。以致灾因子评估方法为理论基础，叠加GIS空间分析技术，对遵义市开展雷电致灾因子危险性区划研究。结果显示：遵义市雷击密度致灾因子区划结果较高，高危险性区域主要集中在市行政中心及赤水中西部；强雷电密度、地闪强度两种致灾因子高危险性区域分布较为零散；雷电灾害致灾因子危险区划中，高危险性区域主要分布于市行政中心、仁怀及桐梓部分区域，该高危险性区域同是人口分布密集，GDP较高的区域，在今后的发展建设中需加强该区域雷电灾害物防、技防、人防能力建设，以减少雷电灾害造成的人员伤亡和财产损失。

Study on hazard zoning of lightning hazard factors in Zunyi

Based on the lightning days data of 14 national weather stations in Zunyi city from 1978 to 2013 and the lightning location data of ADTD from 2006 to 2020, the basic geographic information (including county boundary and water distribution), population and GDP data of Zunyi city were superimposed. On the theoretical basis of disaster factor assessment method, combined with GIS spatial analysis technology, the risk zoning study of lightning disaster factors in Zunyi city was carried out. The results show that the zoning results of lightning density hazard factors in Zunyi city are high, and the high risk areas are mainly concentrated in the administrative center of Zunyi city and central and western Chishui. The distribution of the high risk areas of strong lightning density and ground lightning intensity is scattered. Lightning disaster risk zoning hazard -formative factors in high risk areas are mainly distributed in the municipal administrative center, Renhuai and Tongzi parts, the high risk areas with dense population distribution, higher regional GDP, in the construction of the future development needs to strengthen the regional technology dimension, civil air defense capability, lightning disasters caused by lightning disasters to reduce casualties and property losses.
