【摘要】：我國(guó)面臨中西部工程性缺水、北方資源性缺水和南方水質(zhì)性缺水的嚴(yán)重問(wèn)題,如“脫韁之馬”的水問(wèn)題正極大影響著我國(guó)的人民生活、生態(tài)環(huán)境和社會(huì)生產(chǎn),也是當(dāng)?shù)乜茖W(xué)發(fā)展的一大瓶頸。流域作為水資源的重要儲(chǔ)存介質(zhì)和水質(zhì)發(fā)生生物-物理-化學(xué)反應(yīng)的場(chǎng)所,而河道又是其中的重要一環(huán),如能夠?qū)崿F(xiàn)對(duì)河道的有效管理,達(dá)到科學(xué)合理利用河道資源的目標(biāo),是解決目前水資源問(wèn)題的有效途徑之一。全國(guó)水利信息化發(fā)展“十二五”規(guī)劃中指出對(duì)水利工作的支撐總目標(biāo)包括全面提升信息技術(shù)對(duì)水利日常工作及應(yīng)急處理的支撐與服務(wù)能力,因此實(shí)現(xiàn)河道的信息化使資源的管理更加科學(xué)、規(guī)劃更加合理、利用更加高效,是水利信息管理的中流砥柱也是其綜合體現(xiàn)。 地理信息系統(tǒng)(GIS)是專用于地理空間信息處理和管理的計(jì)算機(jī)技術(shù)系統(tǒng),從上世紀(jì)60年代發(fā)展以來(lái)各項(xiàng)技術(shù)日益成熟并在各行業(yè)中廣為應(yīng)用,它的特性為河道信息化的實(shí)現(xiàn)提供了強(qiáng)有力的工具。本文選用方興未艾的GIS組件ArcEngine9.3為開發(fā)工具,在Visual Studio2005開發(fā)環(huán)境下利用嵌入式開發(fā)技術(shù),結(jié)合SQL Server2005數(shù)據(jù)庫(kù)管理系統(tǒng)和空間數(shù)據(jù)引擎ArcSDE研發(fā)了三川河流域河道的信息管理系統(tǒng)。 首先闡述了三川河流域數(shù)字河道建設(shè)的背景及意義、河道概況和國(guó)內(nèi)外研究發(fā)展概況；其次對(duì)創(chuàng)建系統(tǒng)時(shí)涉及的關(guān)鍵技術(shù)做了匯總,著重介紹了ArcEngine組件技術(shù)及開發(fā)優(yōu)勢(shì)和系統(tǒng)數(shù)據(jù)庫(kù)技術(shù)；然后設(shè)計(jì)了系統(tǒng)的數(shù)據(jù)庫(kù),利用SQL Server2005和空間數(shù)據(jù)引擎對(duì)系統(tǒng)的空間數(shù)據(jù)及屬性數(shù)據(jù)進(jìn)行了邏輯設(shè)計(jì)和物理設(shè)計(jì),達(dá)到對(duì)河道海量數(shù)據(jù)的科學(xué)、高效和統(tǒng)一管理的目標(biāo)；最后實(shí)現(xiàn)系統(tǒng)各模塊功能,系統(tǒng)包含常規(guī)模塊、專用模塊和輔助模塊實(shí)現(xiàn)對(duì)河道資源信息的存儲(chǔ)、編輯、更新、專題查詢、統(tǒng)計(jì)和分析等,成功應(yīng)用于河道資源數(shù)據(jù)的科學(xué)信息化管理并為相關(guān)部門提供分析指導(dǎo)和決策依據(jù)。 研究表明,基于GIS組件技術(shù)ArcEngine能夠自定義創(chuàng)建一個(gè)功能較強(qiáng)、易于擴(kuò)充并具有友好界面的河道信息管理系統(tǒng)并滿足當(dāng)前用戶的需求。作者在ArcEngine應(yīng)用于河道信息管理系統(tǒng)方面做了嘗試,為該系統(tǒng)的繼續(xù)完善和水利信息化其它自定義系統(tǒng)的開發(fā)提供了便捷。
[Abstract]:China is faced with the serious problems of engineering water shortage in the central and western regions, water shortage in the north and water quality in the south, such as the "runaway horse" water problem, which is greatly affecting the people's life, ecological environment and social production in our country. It is also a major bottleneck in the development of local science. As an important storage medium of water resources and a place where biological-physical-chemical reactions take place in water quality, the river channel is an important part of it. For example, it can realize the effective management of river channels and achieve the goal of scientific and rational utilization of river resources. It is one of the effective ways to solve the problem of water resources at present. In the 12th Five-Year Plan for the Development of National Water Resources Informatization, it was pointed out that the overall objectives of supporting water conservancy work include comprehensively enhancing the support and service capacity of information technology for daily water conservancy work and emergency handling. Therefore, realizing the informationization of river channel makes the management of resources more scientific, planning more reasonable, and utilizing more efficiently, which is the mainstay of water conservancy information management and its comprehensive embodiment. Geographic Information system (GIS) is a computer technology system dedicated to geospatial information processing and management. Since its development in the 1960s, various technologies have become increasingly mature and widely used in various industries. Its characteristics provide a powerful tool for the realization of river information. In this paper, we choose the burgeoning GIS component ArcEngine9.3 as the development tool, using embedded development technology under the Visual Studio2005 development environment, combining the SQL Server2005 database management system and the spatial data engine ArcSDE to develop the information management system of Sanchuan river basin. Firstly, the background and significance of digital river channel construction in Sanchuan River Basin, the general situation of river course and the research and development situation at home and abroad are expounded. Secondly, the key technologies involved in the establishment of the system are summarized. This paper mainly introduces the ArcEngine component technology, its development advantage and the system database technology, then designs the database of the system, and makes use of SQL Server2005 and the spatial data engine to carry on the logical design and the physical design to the system spatial data and the attribute data. To achieve the goal of scientific, efficient and unified management of massive river channel data. Finally, the functions of each module of the system are realized. The system includes routine module, special module and auxiliary module to store, edit and update the channel resource information. Thematic inquiry, statistics and analysis have been successfully applied to the scientific information management of river resource data and provide analysis guidance and decision basis for relevant departments. The research shows that ArcEngine based on GIS component technology can create a channel information management system with strong function, easy expansion and friendly interface, and can meet the needs of current users. The author tries to apply ArcEngine to river information management system, which provides convenience for the further improvement of the system and the development of other customized water conservancy information systems.
