基于GIS的城市空气污染综合分析

Comprehensive Analysis Based on GIS of Urban Air Pollution

在城市空气污染的模型研究中,GIS可以作为复杂环境模型的输入数据处理器,而且GIS有一个重要的功能模块——统计分析模块,GIS能够对模型的运算输出数据进行综合处理,并对结果进一步分析,进行有关的查询以及对研究成果的可视化输出。在基于GIS的城市空气污染的综合分析中,我们探究了城市土地利用现状对空气质量的影响,本文采用模糊综合分析法探索城市三大污染源在空气污染中所占的比重,制作城市空气污染等级分布图。GIS在大气污染研究领域可以充分发挥其空间分析和可视化优势,为治理工作提供技术路线。

Model in the study of air pollution in the city, GIS can be used as a complex environment model input data processor, and GIS is a important function of the statistical analysis, GIS can carry on the comprehensive treatment to the model output data, and the analysis of the results further, on the query and visualization output of research results. In the comprehensive analysis based on GIS of urban air pollution, we explore the influence of urban land use status quo on air quality, by fuzzy comprehensive analysis method to explore three big pollution in the air pollution in cities of share, making urban air pollution level distribution. The GIS in the research field of atmosphere pollution can give full play to the advantage in spatial analysis and visualization put forward the technical route for governance work.
