【摘要】：水是人類賴以生存的基礎(chǔ),其中河流水尤為重要,然而近年來(lái)由于工業(yè)的發(fā)展、現(xiàn)代農(nóng)業(yè)的進(jìn)步,在給人們的生活帶來(lái)改進(jìn)的同時(shí),也帶來(lái)了河流的污染。河流的污染不僅給人們的生活環(huán)境帶來(lái)困擾,也給人們的身體健康帶來(lái)威脅。因此,研究河流水環(huán)境模擬系統(tǒng)的發(fā)展演變是十分必要的,無(wú)論對(duì)于長(zhǎng)期排放污水的工廠,還是對(duì)于應(yīng)急污染源,根據(jù)污染物沿河流的變化及時(shí)地采取措施,可以有效地、有針對(duì)性的改善河流環(huán)境。 然而傳統(tǒng)水環(huán)境模擬主要是數(shù)值計(jì)算模擬,沒(méi)有可視化界面,不直觀,操作也不方便。隨著計(jì)算機(jī)技術(shù)和地理信息系統(tǒng)的發(fā)展,將GIS技術(shù)應(yīng)用到各個(gè)跟地理相關(guān)的領(lǐng)域逐漸引起注意,甚至有些已經(jīng)產(chǎn)業(yè)化。而在GIS的應(yīng)用中,水環(huán)境是極為重要的一個(gè)方面,因?yàn)樗木哂忻黠@的地理特征,將GIS技術(shù)應(yīng)用于水環(huán)境模擬是可行而有效的,只是需要解決水環(huán)境數(shù)據(jù)的存儲(chǔ)以及相關(guān)的軟件模塊的實(shí)現(xiàn)。本文正是著眼于GIS與水環(huán)境的結(jié)合而進(jìn)行數(shù)據(jù)存儲(chǔ)結(jié)構(gòu)和模擬系統(tǒng)的研究和開(kāi)發(fā)的。 將GIS技術(shù)與水環(huán)境模擬結(jié)合的系統(tǒng)開(kāi)發(fā)主要涉及水環(huán)境系統(tǒng)模擬模型的選擇、屬性數(shù)據(jù)和空間數(shù)據(jù)的處理、GIS平臺(tái)的選取以及計(jì)算機(jī)模擬實(shí)現(xiàn)。其中水環(huán)境系統(tǒng)模擬模型一般分為數(shù)值模擬和物理模擬,通常以數(shù)值模擬為主,因?yàn)樗哂惺r(shí)和高效等優(yōu)點(diǎn)。而在數(shù)據(jù)的存儲(chǔ)方面,屬性數(shù)據(jù)在選擇好數(shù)據(jù)類型后存放在通用的數(shù)據(jù)庫(kù)中即可,而空間數(shù)據(jù)則需要存儲(chǔ)于空間數(shù)據(jù)庫(kù)中。GIS平臺(tái)則選擇主流的ArcGIS,它具有開(kāi)發(fā)功能強(qiáng)大,省時(shí)省力易實(shí)現(xiàn)等諸多優(yōu)點(diǎn)。然后,借助于C#開(kāi)發(fā)語(yǔ)言和ArcGIS Engine開(kāi)發(fā)包開(kāi)發(fā)出在計(jì)算機(jī)上的水環(huán)境模擬系統(tǒng)。其中按維度包括一維水質(zhì)模擬、二維水質(zhì)模擬和三維水質(zhì)模擬,并調(diào)用Matlab進(jìn)行函數(shù)計(jì)算,設(shè)計(jì)出的水環(huán)境模擬系統(tǒng)能滿足水利部門(mén)的基本需求,在水質(zhì)管理以及應(yīng)急水污染中提供幫助。
[Abstract]:Water is the basis of human survival, among which river water is particularly important. However, due to the development of industry and the progress of modern agriculture in recent years, people's lives are improved at the same time. The pollution of rivers not only brings troubles to people's living environment, but also threatens people's health. Therefore, it is necessary to study the development and evolution of river water environment simulation system. No matter for the factories that discharge sewage for a long time or for the emergency pollution sources, timely measures can be taken according to the changes of pollutants along the river, which can effectively and pertinently improve the river environment. However, the traditional water environment simulation is mainly numerical simulation, no visual interface, not intuitive, not easy to operate. With the development of computer technology and geographic information system. The application of GIS technology to various geographical related fields has gradually attracted attention, and some of them have been industrialized. In the application of GIS, the water environment is an extremely important aspect. Because hydrology has obvious geographical characteristics, it is feasible and effective to apply GIS technology to water environment simulation. It is only necessary to solve the storage of water environment data and the realization of related software modules. This paper focuses on the research and development of data storage structure and simulation system based on the combination of GIS and water environment. The system development which combines the GIS technology with the water environment simulation mainly involves the selection of the water environment system simulation model, the processing of the attribute data and the spatial data. The selection of GIS platform and the realization of computer simulation, in which the simulation model of water environment system is generally divided into numerical simulation and physical simulation, usually mainly numerical simulation. Because of its advantages such as saving time and high efficiency, in the aspect of data storage, attribute data can be stored in a common database after selecting a good data type. The spatial data need to be stored in the spatial database. The GIS platform chooses the mainstream ArcGIS.It has many advantages, such as powerful development function, saving time and labor, and easy to realize. Then. With the help of C # development language and ArcGIS Engine development kit, a water environment simulation system is developed on the computer, in which one dimensional water quality simulation is included according to the dimension. Two-dimensional water quality simulation and three-dimensional water quality simulation, and call Matlab to calculate the function, the designed water environment simulation system can meet the basic needs of water conservancy departments. Assist in water quality management and emergency water pollution.
