Research Of The Suining City Environmental Information System

Now the information technology more and more has been used in social economy each aspect, the information technology is changing our work and the life. For the adaptation time to the environmental protection work's request, as well as the environmental protection work's actual need, established the environmental information system already to become the urgent matter. The environmental information resources'reasonable development, the conformity, full sharing and the effective use have the very vital significance to urban and the local sustainable development and the scientific order's environmental management and the decision-making.Will summarize and profits from the domestic and foreign environmental information system construction the advanced experience and in the future trend of development foundation, Through to the SuiNing environmental information system construction plan's research, unifies in the SuiNing municipal district in the existing information system platform foundation to dump pollutants enterprise's actual situation, the optimization existing environmental information system construction plan. This will enhance all levels of environmental protection bureau environmental protection work enormously the information and the automation, to the source of pollution monitoring and the management level, the enhancement working efficiency, is the macro-scientific policy-making provides a more detailed data pool, was also has laid the foundation for the establishment burst characteristics environmental pollution emergency command system; Utilizes the real-time monitor data pool, the union pollutant proliferation model and the GIS system, the simulator study basin pollution situation, feeds back through the correlation technique in the information system, strengthens to the entire area of jurisdiction key pollution discharge enterprise, the water quality, the atmospheric environment quality effective monitoring and the management; Meanwhile constructs certainly for our country's environment information system's fundamental research and the practice profits from the function.The environmental information system's construction mainly divides into three links:field data gathering, data transmission project design, information monitoring center construction work (receiving end's build). The environmental information system design plan includes:"the system design's thought that the principle, the entire model, in data acquisition system's data transmission plan and agreement provision, the information monitoring center engine room construction and the hardware, the software shaping request, the recombination environment information construction correlation technique standard request, has provided the one whole set plan". And present paper about information system construction goal and system design model analysis; To SuiNing environmental information system and equipment shaping analysis; Introduced briefly to the data acquisition system that lets at the beginning of us slightly understand data acquisition system's structure function; To current transmission plan (PSTN) the analysis, unifies in the SuiNing municipal district to dump pollutants enterprise's actual situation, the analysis contrasts each communication network technical program, selects the GPRS wireless communication network which China moves to take the data transmission platform the importance; In the union information system the pollution outlet real-time monitor data, the utilization two-dimensional water quality model simulator study pollutant's migration proliferation rule, to the FuJiang River SuiNing section basin's influence, the selection typical section and utilizes the computer visualization technology, unifies the GIS system to be able the image to feed back intuitively in the information system; Based on entire information system's design construction, unifies GIS/ES (expert system) the technology, the analytical study establishment burst characteristics environmental pollution emergency command system, simultaneously using burst characteristics environmental pollution emergency command system confirmation entire information system's normal operation.
