| 摘 要： | 分析基于Surfer空气质量模拟结果等值线表达方法的优缺点,探讨基于GIS空气质量模拟结果可视化的技术与方法;借助ArcGIS Engine 9.3,集成Calpuff模型,对气象场、污染浓度时空分布特征与动态演变趋势等进行可视化试验。结果表明,基于GIS的空气质量模拟结果可视化能较好地表达研究区域的大气环境状况,对深入研究污染浓度的时空演变规律、污染影响范围与程度有很强的实际应用价值。 |

| Abstract: | Traditional air quality simulation result is stored in text form.Text-based information is insufficient for pollution spatial-temporal relationship extraction.Therefore,it is necessary to render pollution information through geo-visualization.Based on analysis on both advantage and disadvantage of air quality contour representation,a geo-visualization solution for air quality simulative result is proposed in this paper.Based on Calpuff model,meteorological condition,spatial-temporal distribution of pollution concentration and pollution dynamic pattern is calculated.With help of rendering module in ArcGIS Engine 9.3,simulative result is presented visually.According to rendering result,geo-visualization gains advantage over other methods in air quality simulation representation.Geo-visualization is preferable strategy which could be utilized in analyzing spatial-temporal distribution of pollution concentration. |
