面向煤基能源产业气象服务需求的灾害预警阈值优化研究OA
Research on optimization of early warning thresholds for meteorological disasters in coal-based energy industry
以陕西榆林煤基能源产业为研究对象,构建"致灾因子—工艺参数—经济影响—服务需求"四维调研框架,基于413份企业调研问卷,系统分析了极端天气对煤基全产业链的影响机制.结果表明:气温、降水和风速是影响煤基能源产业运行的三大关键因子,其中强降水、低温冰冻和雷电为主要灾害类型.进一步建立了包括高温、强降水、大风等要素的动态阈值体系,揭示了复合灾害的协同放大效应,并据此提出分级预警机制.研究成果为煤基能源产业应对气候变化提供了科学依据.
Against the backdrop of global warming,the frequent occurrence of extreme weather events poses severe challenges to the safe production and economic operation of energy industries,particularly coal-based industries.This study constructs a four-dimensional research framework of"hazard factor-process parameter-economic impact-service demand",collecting 413 survey questionnaires and conducting field visits to nine typical enterprises.Through quantitative analysis of the correlation between meteorological elements and production parameters,a threshold system for the impact of meteorological disasters on the Yulin coal-based energy industry was established.The main conclusions are as follows.The three dominant meteorological factors affecting the coal-based energy industry are temperature(29.0%),precipitation(24.4%),and wind speed(19.3%).The three major meteorological disasters are heavy precipitation(14.8%),low-temperature freezing(14.2%),and lightning(13.6%).By integrating process parameters and equipment status indicators from different coal-based industries,dynamic thresholds for temperature,precipitation,relative humidity,strong winds,and air pressure variation were proposed.A tiered early-warning mechanism was established,and emergency plans were optimized based on regional climate characteristics to enhance resilience against extreme weather.The synergistic amplification mechanism of compound meteorological disasters was elucidated.The combination of"low temperature-high humidity-calm wind"significantly increased haze pollution concentration compared to individual factors,while the"dry heat-strong wind"combination sharply elevated the risk index of explosion and fire.The threshold system established in this study,based on data from Yulin,has regional limitations.When extended to bases in Shanxi,Inner Mongolia,and other regions,differences in precipitation distribution and wind speed characteristics must be carefully considered for determining critical threshold values.Although this threshold system possesses the capacity for dynamic evolution with technological advancements,climate change,and policy adjustments,future efforts should focus on establishing an update mechanism coupled with climate predictions to achieve proactive adaptive adjustments.
