【摘要】 三峡库区(湖北)农业面源污染负荷、评价及预警系统是对全国第一次污染普查数据研究结果的应用。在明确该区域农业生产和农业面源污染现状的基础上,使用C#语言进行系统编程的实现,通过计算机将种植业源、畜禽养殖业源和农村生活源的有关参数进行污染负荷估算,并对各个县及乡镇的重点污染源和重点污染区域进行风险预测及预警,为政府宏观调控及各级乡镇单元制定农业面源污染防控对策提供支撑。该系统结合Mysql数据库,通过Winform界面将研究结果中的数据以图表、文字的形式显示出来,直观明了的突出农业生产及污染现状,准确地显示出各地区污染预警值,并且通过污染负荷估算为下一步农业生产调整做出指导。更多还原

【Abstract】 "Three Gorges Reservoir Area(Hubei) agricultural non-point source pollution load, evaluation and early warning system" is an application of the first national pollution census data results. On the basis of clarifying the status of agricultural production and agricultural non-point source pollution in the region, using C # Language to realize the system programming,estimating the pollution loads by the parameters of the planting source, livestock and poultry source and the rural life source by computer, and then making the risk prediction and early warning of the key pollution sources and key pollution areas in the counties and rural townships, aims to provide support for the government macro-regulation and make agricultural non-point source pollution prevention and control countermeasures. This system combines Mysql database, the research data are displayed in graphical and text forms by Winform interface, which can highlight the status of agricultural production,pollution, and pollution warning values visually and clearly, and to guide the adjustment of agricultural production through pollution load estimation.更多还原
