摘　　要：石河子地区污染情况日益严重,采用传统分析方法没有考虑风险和风速因素,导致分析结果不精准,因此,使用污染物浓度插值方法研究风速对石河子污染物扩散。分析风向与大气污染关系,依据石河子2015年各月主导风向统计资料,获取主导风向和频率信息,确定风向和风速是影响污染物扩散的主要因子。顾及风向和风速因素,分解矢量数据,得到风向和风速的属性值。构建扩散问题标准模型,确定污染物浓度,计算风场中相邻网格单元间扩散距离。由分析结果可知,污染物浓度插值方法分析结果更加精准。The pollution situation in Shihezi area is getting more and more serious.The traditional analysis method does not consider the risk and wind speed factors,which leads to inaccurate analysis results.Therefore,the pollutant concentration interpolation method is used to study the diffusion of wind speed to Shihezi pollutants.This study analyzes the relationship between wind direction and air pollution,and obtain the leading wind direction and frequency information based on Shihezi's leading wind direction leading wind direction in each month of 2015.The wind direction and wind speed are the main factors affecting the diffusion of pollutants.Taking the wind direction and wind speed into consideration,the vector data is decomposed to obtain the wind direction and wind speed attribute values.Th study constructed a standard model of diffusion problem,determined the concentration of pollutants,and calculated the diffusion distance between adjacent grid cells in the wind field.It is concluded that the analysis result of the pollutant concentration interpolation method is more accurate.
