【摘要】：随着我国城市工业化阶段性发展的特性,城市中工业区与居住区、商业区等区块交错，工业区带来的大气污染物质对周边的环境不可避免地产生着不良影响，给人们的生活、工作造成了一定的困扰。如何即时地了解自身周边企业排放的大气污染物质对环境的影响，是人们面对的现实问题。在上述背景下，本文在真实、可靠、丰富的企业污染源监测数据基础上，致力于通过Web地理信息系统(WebGIS)选取恰当的空气扩散模型，建立企业大气污染物查询与分析系统。WebGIS融网络、计算机图形和地理信息数据库于一体，储存和处理空间信息，能把地理位置和相关属性有机结合起来，满足不同部门、不同用户对空间信息的要求。用户可以借助其空间分析能力和可视化表达，，用于各种辅助决策。本文主要从以下两个方面对系统进行了研究、设计和开发： 1、针对工业企业污染源的特性，选取和优化合适的空气扩散模型，确定大气稳定度和选取扩散参数，对企业大气污染物扩散模式进行了讨论； 2、将WebGIS等相关技术应用到系统设计中，实现了一个企业大气污染物查询与分析的原型系统。系统能查询与分析工业企业排放的污染物质对周边环境产生的影响以及污染物质在大气中扩散的情况，实现了扩散模型的可视化表达和多用户浏览。本课题根据企业污染源特点，建立了比较合理的企业大气污染物查询分析系统，同时对WebGIS技术运用于城市环境影响的应用进行了初步探索与尝试，为用户提供了实时浏览、查询和在线分析工具，提供了一个方便的了解四周生活环境质量的平台。
[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.
