【摘要】 近年来,随着经济社会的快速发展,河流水质污染状况日益严重,而我们的环境监控能力建设相对滞后、水平较低,已不能适应当前环境保护工作新形势和新任务的要求。因此需要建立一套功能更完备、设计更科学的水质自动监控系统。系统采用C/S和B/S相结合的模式,系统访问部分采用B/S模式,系统的开发和实现基于微软Net Framework平台,依靠Visual Studio.Net开发工具,采用C#编程语言实现。新的水质自动监控系统与以往类似的软件相比做出了以下改进：一是根据原始监测数据对水质分类,对监测结果进行定性分析,使监测结果通俗易懂,便于领导和非专业人员查看。二是设定动态目标值,通过污染扩散模型计算动态目标值,消除上游断面污染超标对下游断面产生的影响,对断面是否达标给出更科学的判断。本文主要做了以下几方面的工作：首先,是对地表水水质监测因子的选择以及对监测因子评价方法的选定。其次,根据业务需求分析,绘制业务流程,对系统整体功能和数据库的整体结构进行了设计。再次,对地表水环境质量评价方法进行了分析,根据污染指数计算方法和评价标准,设计公式和数据库并实现。最后,建立污染物衰减模型,分析衰减系数的计算方法,在此基础上设计动态目标值计算模型和数据库并实现。该系统的建成与应用将实现对全省河流水环境质量的有效监控,为全省建立上下游生态补偿机制、环保责任目标考核、总量减排提供技术支持。更多还原

【Abstract】 In recent years,with the rapid development of ecnomic society, River water contamination situation is gradually grave, but our environment is monitor relative ability construction lagging, horizontal lower, already can not adapt to new circumstances of current environmental protection work and new mission call for. Need to build a set of function more completely therefore, design that the science water quality monitors system more voluntarily.System adopt pattern of integration of C/S with B/S, system visits a part adopt the B/S pattern, and systematic exploitation coming true owing to Microsoft. Net Framework platform, depends on Visual Studio. Net develops an implement, adopt the C# programming language to come true. New water quality automatic monitoring system has made the following improvement out compared with in the past similar software:One is in the light of primitive monitor a data classifying to water quality, carry out qualitative analysis on to monitoring result, the messenger is monitored result is popular and easy to understand, professional staff checks the leader and mistake easy to. Two is to set up the development target value, target value calculating development by contaminating the model diffusing, eliminate section contaminates the effect going beyond standard coming into being to lower reaches section upstream, is given to out to if section reach the standard more the science judgement.The main body of a book have done the following job in several aspects mainly:First, be the choice to the earth’s surface water water quality monitoring factor and selected appraising method’s to monitoring a factor.Secondly, draw business technological process according to business need analysis,the overall function and data base entirety structure have carried out design on system.Next, method has carried out analysis on the earth’s surface water environment quality evaluation, reckoning has composed in reply with valuation standard, design formula a data base and realization according to pollution index. Finally, Build the pollution attenuation model, Analyse the attenuation coefficient reckoning, here, design that the development target value calculates the model and the data base and come true on the basis.The establishment and realization of this system will provide technical support in order that the water environmental quality supervisory control can be applied on the whole province river,the Ecological Compensation Mechanism of the up and lower reaches on the whole province river can be built up.Meanwhile it will impact on the environmental protection responsibility target check and the total emission of main contaminants reduction.更多还原
