【摘要】：伴随社会发展、经济进步,在对地下水的供需关系上,黑龙江省农业基地、农场、中小城镇表现出的关系越来越密切。因为缺乏水环境保护意识,地下水的不合理利用和开发情况越来越严重,并伴随工厂的不合理排放废水、农业耕种上化肥农药超标使用、居民生活用水不按规定任意排放,导致地下水水质情况日益恶化,质量下降,污染严重。因此,结合黑龙江省庆安县各个城镇及853农场现状为例进行地下水水质环境评价,对当地水位、地质、社会经济、工农业现状进行综合分析,确定地下水受污染情况,评价地下水等级现状,根据所得结论提出地下水水质保护意见,采取措施防止二次污染,改善水质现状。本文将在以下几个方面进行研究。论文查取相关国内外文献,综合目前国内外水环境相关问题的研究现状,随着计算机的快速发展,提出了其在水环境管理上方便快捷的作用和使用趋势。本文根据编程软件特点,选取Visual Basic 6.0(以下简称VB)作为界面开发工具,根据MATLAB在数据处理上的优势,选取MATLAB作为处理工具,论证了二者之间可以进行无缝连接、混合编程应用的可行性,确定研究目标、技术可行性依据、系统完整设计步骤、主要功能实现方式以及所需计算机配置等内容。论文研究获得如下成绩:利用VB编程实现层次分析算法,结合实际情况实现评价因子对水环境质量影响权重分析;根据VB编程调用储存在EXCEL中的数据资料,集合混合编程实现不同算法的水环境质量评价,并可将评价结果可视化显示,实现用户界面管理等功能。本文以庆安县及三江平原853农场水质检测资料进行实例分析,查找相关文献对研究区域的情况作出系统、综合性论述。其中包括研究区域自然环境、社会经济环境、水资源情况等方面。区域水质质量评价采用内梅罗指数法、熵权模糊综合评价、组和权重模糊评价,得到了研究区域水质等级现状。并结合当地实际情况,运用层次分析法确定各评价因子对水质等级的影响大小。确定影响水环境质量的主要因素,本文通过已有的水质检测资料进行综合的分析,结合当地实际,分析讨论评价结果基本符合实情。论文最后根据当地实际情况和评价结果提出可行性预防办法和相应的防治措施,为当地政府治理地下水水环境提出可行性参考建议。本文以混合编程为主线路建立水环境管理系统,结合当前普遍的水质评价方法,为水质管理人员搭建一个计算机管理平台。其优势在于方便快捷、拥有良好的操作界面、提高工作效率的特点,有利于中小型城镇水环境信息系统管理。
[Abstract]:Along with social development and economic progress, the relationship between agricultural bases, farms, and small and medium-sized towns in Heilongjiang Province has become more and more close in terms of the supply and demand relationship for groundwater. Because of the lack of water environmental protection consciousness, The unreasonable utilization and exploitation of groundwater are becoming more and more serious, and accompanied by the unreasonable discharge of wastewater from factories, the use of chemical fertilizers and pesticides in agricultural cultivation exceeds the standard, and the domestic water is not discharged arbitrarily according to regulations, which leads to the worsening of groundwater quality. As a result, combined with the present situation of various towns and 853 farms in Qingan County, Heilongjiang Province, the groundwater quality and environment were evaluated, and the local water level, geology, social economy, and the present situation of industry and agriculture were comprehensively analyzed. To determine the situation of groundwater pollution, to evaluate the present situation of groundwater grade, to put forward the opinions on the protection of groundwater quality according to the conclusions, and to take measures to prevent secondary pollution, To improve the water quality. This paper will study in the following aspects. The paper looks up the relevant domestic and foreign literature, synthesizes the current research status of the domestic and foreign water environment related problems, with the rapid development of the computer, According to the characteristics of programming software, Visual Basic 6.0 (hereinafter referred to as VB6.0) is selected as interface development tool. According to the advantages of MATLAB in data processing, MATLAB is selected as processing tool. It demonstrates the feasibility of seamless connection between the two, the feasibility of hybrid programming, the determination of research objectives, the technical feasibility basis, and the complete design steps of the system. In this paper, the following achievements are obtained: using VB programming to realize the AHP algorithm, combining with the actual situation to realize the weight analysis of the impact of evaluation factors on the quality of water environment; According to VB programming, the data stored in EXCEL are called, and mixed programming is used to realize the evaluation of water environment quality of different algorithms, and the evaluation results can be visualized. To realize the function of user interface management, this paper analyzes the water quality test data of Qingan County and 853 Farm in Sanjiang Plain, finds the relevant documents and makes a systematic and comprehensive discussion on the situation of the study area, including the natural environment of the research area. In the aspects of social and economic environment, water resources and so on, the evaluation of regional water quality is based on the method of Nemero index, the fuzzy comprehensive evaluation of entropy weight, the fuzzy evaluation of group and weight, and the present situation of water quality grade in the study area. Using AHP to determine the influence of each evaluation factor on the water quality grade, and to determine the main factors affecting the quality of water environment, this paper makes a comprehensive analysis through the existing water quality inspection data, combining with the local reality. The analysis and discussion of the evaluation results basically accord with the actual situation. Finally, according to the local actual situation and the evaluation results, the paper puts forward the feasible preventive measures and corresponding prevention measures. In this paper, a water environment management system based on mixed programming is established, which is combined with the current water quality evaluation method. The advantages of a computer platform for water quality management are that it is convenient and quick, has a good operating interface, improves the working efficiency, and is conducive to the management of water environment information system in small and medium-sized cities and towns.
