| 摘 要： | 利用广东省环境信息GIS综合发布平台发布的2005—2010年间珠三角区域范围内空气质量日报中空气质量等级数据,采用网格化分析、空间统计分析、专题图分级渲染模型,对珠三角区域的空气质量时空演化特征和影响因素进行研究,结果表明各周期年度珠三角区域网格空气质量频数统计上近似呈正态分布,近5来空气质量空间分布形态由以东莞、佛山为污染中心的哑铃形向以佛山中部为中心并且长轴为西北-东南向的椭圆形演化。

| Abstract: | Based on the Air Quality Level data distributed between 2005 and 2010 by the GIS Platform of the Environmental Monitoring Center in Guangdong province, the Spatial and temporal evolution characteristics and reasons on Air Quality Level in Pearl River Delta in recent five years is studied with the models of analysis of grid, spatial statistics, and the rendering thematic map. The result is that the grids's frequency of the mean of RAQI in each year shows statistically normal distribution.The spatial shape of the air quality in this area is changed from the dumbbell with the center of Dongguan and Foshan to the ellipse whose long axis is nwse-trending and center is in Foshan. |
