【摘要】：近年来,国内外农业灾害频频发生,给社会、公众及对生态环境带来严重的危害。分析目前的现状我们发现由于缺乏科学的应急管理体系和完善的部门协调机制,导致事故的预防不够及时有效；由于缺乏科学的防范、应急措施以及应急决策支持系统的辅助支撑,导致事故发生后,不知如何处理与应对,引起事故范围的扩大和事态的进一步恶化。本文研究的目的是针对农业自然灾害应急管理中存在的上述问题,建立科学的管理体系和应急管理系统,以此提高农业灾害应急管理水平和应急辅助决策的能力。因此,本文确定以农业灾害的数据关联与管理关键技术研究、农业灾害应急管理系统为主要研究内容的结构体系；通过收集和研读大量国内外文献,并采用实地调查研究、理论设计研究、实例验证等方法,开展了本次论文的研究工作,取得了如下主要结论和成果。1.针对目前存在的问题,分析现有的应急管理体系构成,引入知识发现体系,应用数据挖掘技术,分别从数据挖掘和农业灾害管理知识入手构建管理系统,搭建农业灾害应急管理系统的基本框架；2.分别对底层所需空间数据、外来数据的获取和系统的实现技术进行研究,将关联规则成功地应用到管理系统中,形成了较为完美的应急管理体系。实验效果表明,本文设计的农业灾害应急管理系统具有较高的支持度,能够为以后的农业灾害预测提供有价值的理论和技术依据。论文最后一章在总结全文工作的基础上,对农业灾害应急管理系统的发展方向进行了展望,分析目前研究存在的不足以及提出后续研究工作的思路,对进一步的研究具有一定的指导意义。
[Abstract]:In recent years, the frequent occurrence of agricultural disasters at home and abroad has brought serious harm to the society, the public and the ecological environment. By analyzing the present situation, we find that the prevention of accidents is not timely and effective due to the lack of the scientific emergency management system and the perfect department coordination mechanism, and the lack of scientific prevention, emergency measures and the auxiliary support of the emergency decision support system can lead to the occurrence of the accident. I do not know how to deal with and deal with, cause the expansion of the accident scope and the further deterioration of the situation. The purpose of this paper is to establish a scientific management system and an emergency management system for the above-mentioned problems in the emergency management of agricultural natural disasters, so as to improve the emergency management level of the agricultural disaster and the ability of the emergency-assisted decision-making. Therefore, this paper determines the key technology research of data association and management of agricultural disaster, the structure system of the main research content of the agricultural disaster emergency management system, and through the collection and study of a large number of domestic and foreign documents, and using field survey, theoretical design research, example verification and other methods, The research work of this paper has been carried out, and the following main conclusions and results are obtained. Aiming at the existing problems, the paper analyzes the existing emergency management system, introduces the knowledge discovery system, and applies the data mining technology to construct the management system from the knowledge of data mining and the management of the agricultural disaster, and set up the basic framework of the emergency management system of the agricultural disaster. Based on the research of the required spatial data, the acquisition of foreign data and the implementation of the system, the association rules are successfully applied to the management system, and a more perfect emergency management system is formed. The experimental results show that the agricultural disaster emergency management system designed in this paper has a high degree of support and can provide valuable theoretical and technical basis for future agricultural disaster prediction. In the last chapter of the thesis, on the basis of the full-text work, the development direction of the emergency management system of the agricultural disaster is prospected, the shortcomings of the present research and the thought of the follow-up research work are analyzed, and the further research has certain guiding significance.
