| 摘 要： | 为表现环境影响评价信息的空间特征与属性特征的关系，提出基于GIS的点源大气环评可视化的自适应图形处理方法。针对现有图形处理技术在GIS开发中的不足，提出基于大气污染物浓度分布的自适应网格划分方法和一种新的等值线、区域填充快速生成算法，实现对GIS环评结果的快速可视化显示与分析。

| Abstract: | To analyze the attribute characteristic and geo-spatial feature of atmospheric Environmental Impact Assessment(EIA), this paper presents a processing method of self-adaptive graphic for visualization of GIS-based point source atmospheric EIA. A self-adaptively grid partition algorithm based on the spreading attribute of the point source atmospheric pollutant, and a new contour, area filling algorithm and proposed. It visualizes and analyzes the result of GIS-based EIA fleetly. |
