Abstract: | 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. |
