摘要: |
选取2010-2017年威宁县37个炮站收集的降雹资料,以降雹次数和灾情资料等数据为基础,通过空间分析和数理统计等方法分析威宁县近8年的降雹资料。研究发现:(1)威宁当地气候、农作物种植时间与冰雹成灾次数之间有一定的关系;(2)冰雹落点受炮站布局和地形等因素影响,以雪山镇为中心区的南北走向的一条多雹带,县内多局地单点性降雹。(3)通过利用威宁县降雹概率分布图,可以为防雹作业指挥和冰雹自动化观测设备规划布局提供一定的理论依据。 |

Abstract: |
The study have selected hail shooting data which collected from 37 artillery stations in Weining county from 2010 to 2017. These data are based on data such as hail shooting frequency and disaster data. Hail shooting data in Weining county in recent 8 years were analyzed by spatial analysis and mathematical statistics. The study has found that: (1) there is a certain relationship between the local climate, planting time of crops and the number of hail disasters in Weining county. (2) the falling point of hail is affected by factors such as the layout of the gun station and terrain. A hail belt with snow mountain town as its central area running from north to south causes multi-local single point hail shooting in the county. (3) By using the hail probability distribution map of Weining county, it can provide certain theoretical basis for hail suppression operation command and hail automatic observation equipment planning and layout. |
