蝗虫防治指挥辅助信息系统设计与实现

Design and Realization of Locust Prevention and Control Auxiliary Information System

为了满足当前蝗虫防治信息化的实际需求,提出以信息技术为基础,研发蝗虫防治指挥辅助信息系统的构想。根据蝗虫发生的特点和防治的需求,讨论了GIS技术在蝗虫防治指挥辅助信息系统中的应用,包括系统的体系结构、功能模块划分以及采用的关键技术,并设计和实现了蝗虫防治指挥辅助信息系统。系统实现了采样点蝗虫发生情况和蝗虫发生区发生程度空间信息分类显示、勾绘蝗虫发生区、统计分析蝗虫发生情况、输出蝗虫发生程度专题图等,为蝗虫防治决策提供科学依据,推动了蝗虫防治的信息化。

This paper was based on information technology and established a framework of the locust prevention and control auxiliary information system,in order to meet the practical information requirement of the locust prevention.According to the feature of the locusts and the prevention demand,the paper discussed the application of GIS technology in locust prevention and control auxiliary information system,including system architecture,division of functional modules and key technology.Furthermore,this paper designed and implemented the locust prevention and control auxiliary information system.System was able to show the information of sample points,map the locust breeding area,displayed the level of the locust breeding area,calculated and analyzed the status of locusts occurrence,created locust occurrence's map,etc.These information provided scientific proof to the decision making about the prevention of the locust and promote the informatization of the prevention.
