【摘要】：随着我国气象事业的不断发展,天气预报及灾情服务工作显得越来越重要。与此同时,受全球工业及其它因素影响,全球气候条件也在不断恶化,气候变暖大势所趋、极端天气现象频发,人们生产生活受到很大影响,国民经济也受到不同程度的损失。大连位于中国辽东半岛南端,且地貌地形复杂,受季风环流影响明显。因此,大连也是全国气象灾害发生较为频繁的地区之一。建立大连地区气象灾情信息共享系统有助于推动大连防灾减灾工作更快更好的发展。系统的开发与设计要遵守规范、准确的气象灾情信息管理基本准则。根据实际交互需要,系统开发语言采用ASP.NET和VB6.0两种,管理员在数据入库及用户查询在数据交互时分别为C/S和B/S方式。系统数据库为SQL SERVER2008数据库。系统需求分析从业务流程出发分为业务应用需求分析和功能需求分析。采用UML建模及用例图相结合的思想,科学规范化的描述了气象业务用户对系统的管理和操作。系统的设计阶段,根据设计原则绘制了整体框架结构图和功能模块图,特别对用户查询功能设计给出了详细设计,指明了查询显示的方式。系统数据库设计采用E-R图的思想,分为常规地面观测数据库和气象灾害数据库两种,分别记录常规气象观测信息和灾情信息。本系统通过收集大连市民政局、气象局、交通局、水务局等部门气象灾情相关信息,根据气象灾害大典的规范要求,整理了自1949年至2016年上半年大连地区发生的暴雨、干旱、霜冻、冰雹、大风及雷电等全部的气象灾情数据资料,并经过统一格式规范整理后存入后台数据库中。根据用户权限不同,系统实现了管理员对数据的规范和安全管理,其他用户可以实现数据查询、导出和统计。其中查询显示方式有柱状图、折线图等多种样式。整套系统较好地实现了大连地区气象灾情信息的共享服务功能,符合气象业务用户操作和使用习惯。系统对预报员及时了解和掌握本地区气象灾害发生的时段、频次等信息,对指导预报、预警及决策服务工作具有较强的现实意义。
[Abstract]:With the continuous development of meteorology in China, weather forecast and disaster service are becoming more and more important. At the same time, the global climate conditions are deteriorating because of the influence of global industry and other factors. Climate warming trend, frequent extreme weather phenomena, people's production and life have been greatly affected, the national economy has also suffered varying degrees of loss. Dalian is located in the southern end of the Liaodong Peninsula in China, and the landform is complex. Obviously affected by the monsoon circulation. Dalian is also one of the regions where meteorological disasters occur more frequently in China. The establishment of the information sharing system of meteorological disasters in Dalian is helpful to promote the rapid and better development of the disaster prevention and mitigation work in Dalian. The development and design of the system should be complied with. The norm. Accurate basic criteria of meteorological disaster information management. According to the actual needs of interaction, ASP.NET and VB6.0 are adopted in the system development language. Administrators in the database and user queries in the data exchange for C / S and B / S mode respectively. The system database for SQL. SERVER2008 database. System requirement analysis is divided into business application requirement analysis and function requirement analysis from business process. The idea of combining UML modeling with use case diagram is adopted. Scientific and standardized description of the management and operation of the system. The system design phase, according to the design principles to draw the overall framework structure diagram and function module diagram. In particular, the detailed design of user query function is given, and the way of query display is pointed out. The system database design adopts the idea of E-R diagram, which is divided into two kinds: conventional ground observation database and meteorological disaster database. The system collects the meteorological disaster information of Dalian Civil Affairs Bureau, Meteorological Bureau, Traffic Bureau, Water Bureau and other departments, according to the requirements of the meteorological disaster code. The data of rainstorm, drought, frost, hail, gale and lightning in Dalian from 1949 to 2016 were collected. According to the different user rights, the system realizes the administrator's data standard and security management, and other users can realize the data query. Export and statistics. Among them, query display mode includes histogram, broken line map and so on. The whole system realizes the sharing service function of weather disaster information in Dalian area. In line with the operational and usage habits of meteorological users, the system timely understands and grasps the time period and frequency of meteorological disasters occurring in the region, and guides the forecast. The work of early warning and decision-making service is of great practical significance.
