地质灾害气象风险预警实时检验客观工具关键技术及应用

中国气象局灾害管理系统中地质灾害关键词和灾害发生时间具有多种组织结构的信息特征,灾害信息分析依赖于人工,不利于地质灾害气象风险预警检验的实时性和客观化。本文结合灾情信息特征和中文自然语言处理软件包Jieba研发了地质灾害多元灾情信息智能分析技术,开发了地质灾害气象风险预警实时检验客观工具。检验工具集成了多元灾害信息智能分析,业务检验方法为主检验主客观预警,检验结果产品自动化输出等功能,可实现预警检验全部流程。2015—2019年地质灾害气象风险预警检验应用表明,实时检验客观工具提取灾害信息准确率达到97%,检验效率高,实时性和集成化优势明显。

Development of a Real-Time Verification Objective Tool for Meteorological Risk Warning to Geological Hazards

The hazard information was collected manually for keywords and the occurrence time of geological hazards in the hazard management system of the Chinese Meteorological Administration, which have multiple organization structures in information characteristics and are thus adverse to the real time property and objectivity of verification for meteorological risk warning to geological hazard. In this study, an objective technique of intelligent analysis for multiple information of geological hazards by computer and a real time verification objective tool for meteorological risk warning to geological hazard are developed based on the characteristic analysis of hazard reports and a natural language processing software named Jieba. This objective tool can accomplish all the processes of verification by integrating functions of hazard information analysis, verification to objective and subjective meteorological risk warning to geological hazards, and output verification result products automatically. Verification for meteorological risk warning to geological hazards from 2015 to 2019 shows that the objective tool has an accuracy rate of 97% in gathering hazard information, higher efficiency in analyzing hazards and verifying meteorological risk warning, which has obvious advantages of real time and integration compared with similar tools.
