【摘要】：随着传统能源的日渐枯竭,核能得到越来越多的应用。核能的发展在为人类带来巨大利益的同时,也带来了不少核污染问题。当发生严重核事故时,决策者需要大量的信息用于决策,其中大部分信息具有一定的空间分布。利用地理信息系统来处理这些事故信息,就可以快速有效地为决策者提供相关信息。本文以中国原子能科学研究院的辐射环境应急监测系统项目为研究背景,重点研究基于GIS平台的监测和评价数据展示。主要研究内容如下： (1)根据系统的功能需求,确定了以Visual Studio2005为集成开发环境,以SQLServer2008为数据库平台,将ArcGIS Engine9.3组件嵌入到开发环境中进行GIS开发的方式。 (2)在系统需求分析的基础上,完成了系统的功能设计和数据库设计。其中功能设计包括地图管理、数据的GIS展示、数据查询和监测数据统计。数据库设计包括空间数据设计和属性数据设计。 (3)在总体分析与设计的基础上,分别实现了地图管理、数据的GIS展示、数据查询和监测数据统计四大功能模块。其中,地图管理模块重点研究了地图查询。数据查询模块提供了五种查询方式。监测数据统计模块提供了三种统计方式。 (4)在数据的GIS展示中,重点研究了创建并编辑要素类、气泡框的展示、等值线的绘制、静态和动态展示等值线渲染图以及风场的绘制等问题。实验表明,系统能在GIS地图上形象地展示监测数据及后果评价结果,并具有数据查询和数据统计功能,从而为应急响应提供数据支持。
[Abstract]:With the depletion of traditional energy, nuclear energy has been used more and more.The development of nuclear energy not only brings great benefits to mankind, but also brings a lot of nuclear pollution problems.When a serious nuclear accident occurs, decision makers need a lot of information for decision-making, most of which have a certain spatial distribution.Using geographic information system (GIS) to deal with these accident information can quickly and effectively provide relevant information for decision makers.Based on the project of radiation environment emergency monitoring system of China Atomic Energy Research Institute, this paper focuses on the display of monitoring and evaluation data based on GIS platform.The main contents of the study are as follows:1) according to the functional requirements of the system, the way of embedding ArcGIS Engine9.3 components into the development environment for GIS development using Visual Studio2005 as the integrated development environment and SQLServer2008 as the database platform is determined.2) on the basis of system requirement analysis, the function design and database design of the system are completed.The functional design includes map management, data GIS display, data query and monitoring data statistics.Database design includes spatial data design and attribute data design.On the basis of overall analysis and design, four functional modules of map management, data GIS display, data query and monitoring data statistics are implemented respectively.Among them, the map management module focuses on the map query.The data query module provides five query modes.The statistical module of monitoring data provides three statistical methods.In the GIS display of the data, the problems of creating and editing the element class, displaying the bubble frame, drawing the isoline, rendering the static and dynamic display isoline, and drawing the wind field are studied.The experimental results show that the system can display the monitoring data and the result of consequence evaluation vividly on the GIS map, and has the functions of data query and data statistics, thus providing data support for emergency response.
