基于组件GIS技术的海水入侵灾害监测信息系统
|
摘要
海水入侵是现代社会具有特色的资源与环境问题,是沿海地区常见的环境恶化现象。目前,全世界已经有几十个国家和地区发现了海水入侵问题,给各国沿海地区带来严重危害,造成巨大经济损失,严重阻碍社会、经济的持续发展。辽宁省海岸线全长2178.3km,大连、锦州、葫芦岛等多地已经出现严重的海水入侵现象,造成耕地减少、设备腐蚀等问题,严重影响了人们的生活。因此,开展海水入侵研究,防止和减轻海水入侵的危害,具有重要的理论意义和科学价值。
传统的数据分析与处理方法已经难以满足海洋数据处理要求,而地理信息系统的出现为这一问题的解决提供了良好的途径。论文将GIS技术引进海洋领域,使海洋信息数据的建库和管理向科学化、可视化、便捷化方向发展,有助于实现海洋信息数据的自动化成图和成果资料的网络发布、共享。组件式GIS的基本思想是把各大功能模块划分为几个控件,每个控件完成不同的功能。各个GIS控件之间、以及GIS控件与其它非GIS控件之间,可以方便地通过可视化的软件开发工具集成起来,形成最终的GIS应用。
本论文采用组件式GIS软件MapXtreme2005与可视化编程软件C#.NET相结合,对系统的开发目标、建设原则、体系结构和功能模块等进行了详细描述,开发具有数据管理、图形管理、信息查询和统计分析等多种功能的计算机辅助规划及信息管理系统。对海水入侵长期监测数据进行各种处理、实现对数据的有效管理和多因素综合分析,迅速地获取满足应用需要的信息,提高对海水入侵灾害的综合管理能力,为科学研究与管理决策提供技术依据。
Seawater invasion is a characteristic problem of resources and environment in modem society;it is a common environmental degradation phenomenon in coastal area. At present,there are dozens of countries and regions with the problem of seawater invasion around the world.The seawater invasion is bringing serious hazards to coastal countries,causing enormous economic loss,and greatly blocking the society and economic sustainable development.The coastline of Liaoning Province is 2178.3km,a lot of regions,such as Dalian,Jinzhou and Huludao,have serious problem of seawater invasion,causing problems of arable land reduction and equipment corrosion,seriously affected people's lives.Thus,it's of great value and sense to carry out research in seawater invasion,prevent against and mitigate the seawater invasion.
The conventional methods of data analysis and management are out of date to meet the demand of ocean data processing;the appearance of GIS provides a good way for this problem.This dissertation will introduce the GIS technology into the field of ocean, enable the database construction and management of ocean data more scientific, visualizing and facilitative,this can be helpful for the network issuance and share of ocean information.The basic idea of ComGIS is to divide the major function module into several controls,each control accomplish different function.Different GIS controls and non-GIS controls can be integrated expediently through visualizing software development tools,then form the ultimate application of GIS.
The main functions of the system are developed by MapXtreme2005 which is a software of ComGIS and C#.NET,particularly described the system develop objective, construction principles,system structure and function modules.The purpose of the dissertation is to develop a computer aided planning and information management system with the function of data management,graphics management,information query and statistical analysis.Through varieties of processing on long-term seawater intrusion monitoring data,achieve effective management of data and integrate analysis of many factors,rapid access to information that meets the application needs,so that we can raise the ability of integrate management on seawater invasion,and provide technical basis for scientific research and management decision-making.
