[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.
