【摘要】：随着地理信息系统(GIS)处理分析与可视化技术的快速发展,GIS在环境保护、国土管理、城市规划等领域中得到了越来越广泛的应用。由于生态水文信息具有监测时间密集、采集数据量大、监测指标复杂等特点,需在传统的水文信息管理方式基础上,对水文信息进行有效的整合、查询、综合分析及可视化。因此利用GIS高效、灵活的空间数据管理和分析能力,结合水文模型,集成水文信息,能够很好地解决水文数据管理的空间操作和可视化表达等问题,使水文信息数字化、可视化、社会化,并对水文水资源管理、水质污染治理和水文灾害预警等方面具有重要的应用价值和现实意义。论文的主要研究内容如下：(1)研究Flex技术及其与GIS结合的技术基础通过研究集成Flex技术,对各SWF文件采用Module缓存处理技术,客户端可下载、压缩并存储地图数据至本地,解决武夷山生态水文信息分析和处理涉及数据内容多、数据量大的数据访问瓶颈,提高系统的响应速度。此外,采用基于Flex的WebService方式访问远程服务,通过Web服务提供的相容标准,进行武夷山生态水文监测数据库的后台访问,提高GIS应用不同软件模块相互交互的效率。(2)研究水文评价及模拟模型,开展武夷山生态水文监测模拟系统设计根据武夷山生态水文信息分析及其评价要求,建立水文评价及模拟模型——模糊综合评价法和灰色系统评价模型,对武夷山水文监测站点采集的水文信息进行综合分析及预测模拟。采用ArcGIS Server 10作为模拟系统的可视化平台,在Flex开发环境下构建与集成水文评价及模拟模型,设计了武夷山水文信息监测预测和模拟功能,如水位实时监测模拟、水质评价及预测等。(3)构建基于RIA技术的武夷山生态水文监测动态模拟GIS系统在上述关键技术研究与模拟模型设计的基础上,基于RIA技术架构,集成FusionWidgets for Flex和 FusionCharts for Flex,建立武夷山生态水文监测管理系统,实现武夷山生态监测的水位、降雨、水质及其污染信息等图文一体的动态可视化展现,达到武夷山生态水文信息数据共享及动态监测的目的,为武夷山水文信息监测提供科学的方法。
[Abstract]:With the rapid development of GIS processing, analysis and visualization technology, (GIS) has been applied more and more widely in the fields of environmental protection, land management, urban planning and so on. Because ecological hydrological information has the characteristics of dense monitoring time, large amount of data collected and complex monitoring indexes, it is necessary to integrate, query, analyze and visualize hydrological information effectively on the basis of traditional hydrological information management method. Therefore, using GIS's efficient and flexible spatial data management and analysis ability, combining with hydrological model and integrating hydrological information, it can solve the problems of spatial operation and visualization of hydrological data management, and digitize hydrological information. Visualization, socialization and application of water resources management, water pollution control and hydrological disaster warning are of great value and practical significance. The main contents of this paper are as follows: (1) Research on Flex technology and its combination with GIS. Through the research of integrated Flex technology, Module cache processing technology is used for each SWF file. The client can download, compress and store map data to the local area. The analysis and processing of ecological hydrological information in Wuyi Mountain can improve the response speed of the system by solving the bottleneck of data access which involves a lot of data content and large amount of data. In addition, the remote service is accessed by WebService based on Flex, and the backstage access to the ecological hydrological monitoring database of Wuyishan is carried out through the compatible standard provided by the Web service. The efficiency of interaction between different software modules in GIS is improved. (2) the hydrological evaluation and simulation model are studied, and the design of ecological hydrological monitoring simulation system in Wuyishan is carried out according to the requirements of analysis and evaluation of ecological hydrological information in Wuyishan. The hydrological evaluation and simulation model-fuzzy comprehensive evaluation method and grey system evaluation model were established to analyze and predict the hydrological information collected from the hydrological monitoring station in Wuyishan. Using ArcGIS Server 10 as the visual platform of the simulation system, the hydrological evaluation and simulation model is constructed and integrated under the Flex development environment, and the monitoring, forecasting and simulation functions of the hydrological information in Wuyishan are designed, such as real-time monitoring and simulation of water level. Water quality evaluation and prediction etc. (3) the dynamic simulation GIS system of Wuyishan ecological hydrology monitoring based on RIA technology is constructed. Based on the above key technology research and simulation model design, the system is based on the framework of RIA technology. The ecological hydrological monitoring management system of Wuyishan is established by integrating FusionWidgets for Flex and FusionCharts for Flex, to realize the dynamic visualization of water level, rainfall, water quality and pollution information of Wuyishan ecological monitoring. The purpose of data sharing and dynamic monitoring of ecological hydrological information in Wuyi Mountain is achieved, and a scientific method for monitoring hydrological information in Wuyi Mountain is provided.
