【摘要】：隨著地理信息系統(tǒng)(GIS)處理分析與可視化技術的快速發(fā)展,GIS在環(huán)境保護、國土管理、城市規(guī)劃等領域中得到了越來越廣泛的應用。由于生態(tài)水文信息具有監(jiān)測時間密集、采集數(shù)據(jù)量大、監(jiān)測指標復雜等特點,需在傳統(tǒng)的水文信息管理方式基礎上,對水文信息進行有效的整合、查詢、綜合分析及可視化。因此利用GIS高效、靈活的空間數(shù)據(jù)管理和分析能力,結合水文模型,集成水文信息,能夠很好地解決水文數(shù)據(jù)管理的空間操作和可視化表達等問題,使水文信息數(shù)字化、可視化、社會化,并對水文水資源管理、水質污染治理和水文災害預警等方面具有重要的應用價值和現(xiàn)實意義。論文的主要研究內(nèi)容如下：(1)研究Flex技術及其與GIS結合的技術基礎通過研究集成Flex技術,對各SWF文件采用Module緩存處理技術,客戶端可下載、壓縮并存儲地圖數(shù)據(jù)至本地,解決武夷山生態(tài)水文信息分析和處理涉及數(shù)據(jù)內(nèi)容多、數(shù)據(jù)量大的數(shù)據(jù)訪問瓶頸,提高系統(tǒng)的響應速度。此外,采用基于Flex的WebService方式訪問遠程服務,通過Web服務提供的相容標準,進行武夷山生態(tài)水文監(jiān)測數(shù)據(jù)庫的后臺訪問,提高GIS應用不同軟件模塊相互交互的效率。(2)研究水文評價及模擬模型,開展武夷山生態(tài)水文監(jiān)測模擬系統(tǒng)設計根據(jù)武夷山生態(tài)水文信息分析及其評價要求,建立水文評價及模擬模型——模糊綜合評價法和灰色系統(tǒng)評價模型,對武夷山水文監(jiān)測站點采集的水文信息進行綜合分析及預測模擬。采用ArcGIS Server 10作為模擬系統(tǒng)的可視化平臺,在Flex開發(fā)環(huán)境下構建與集成水文評價及模擬模型,設計了武夷山水文信息監(jiān)測預測和模擬功能,如水位實時監(jiān)測模擬、水質評價及預測等。(3)構建基于RIA技術的武夷山生態(tài)水文監(jiān)測動態(tài)模擬GIS系統(tǒng)在上述關鍵技術研究與模擬模型設計的基礎上,基于RIA技術架構,集成FusionWidgets for Flex和 FusionCharts for Flex,建立武夷山生態(tài)水文監(jiān)測管理系統(tǒng),實現(xiàn)武夷山生態(tài)監(jiān)測的水位、降雨、水質及其污染信息等圖文一體的動態(tài)可視化展現(xiàn),達到武夷山生態(tài)水文信息數(shù)據(jù)共享及動態(tài)監(jiān)測的目的,為武夷山水文信息監(jiān)測提供科學的方法。
[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.
