基于WebGIS的企業(yè)大氣污染物查詢分析系統的設計與實現
[Abstract]:With the characteristic of the stage development of urban industrialization in our country, the industrial area in the city is interlaced with the residential area, the commercial district, and so on. The air pollution material brought by the industrial zone inevitably has a negative impact on the surrounding environment and gives people's life. The work caused some trouble. It is a realistic problem that how to understand the environmental impact of the air pollutants emitted by the surrounding enterprises. Under the above background, on the basis of the real, reliable and abundant enterprise pollution source monitoring data, this paper is devoted to selecting the appropriate air diffusion model through Web Geographic Information system (WebGIS). Establish enterprise air pollutant inquiry and analysis system. WebGIS integrates network, computer graphics and geographic information database, stores and processes spatial information, can combine geographical location and related attributes organically to satisfy different departments, Different users of spatial information requirements. Users can use their spatial analysis ability and visual representation for various auxiliary decisions. This paper mainly studies the system from the following two aspects: 1. According to the characteristics of the pollution sources of industrial enterprises, select and optimize the appropriate air diffusion model, determine the atmospheric stability and select the diffusion parameters. The diffusion model of atmospheric pollutants in enterprises is discussed. Secondly, the WebGIS and other related technologies are applied to the system design, and a prototype system for query and analysis of atmospheric pollutants in enterprises is implemented. The system can query and analyze the impact of the pollutants emitted by industrial enterprises on the surrounding environment and the diffusion of pollutants in the atmosphere, and realize the visual expression of diffusion model and multi-user browsing. According to the characteristics of enterprise pollution sources, a reasonable enterprise atmospheric pollutant query and analysis system is set up in this paper. At the same time, the application of WebGIS technology to urban environmental impact is preliminarily explored and tried, which provides users with real-time browsing. Query and online analysis tools, provides a convenient understanding of the quality of living environment around the platform.
