乡村振兴背景下工业园区周边空气污染物浓度分布测定方法研究

Method for Measuring Concentration Distribution of Air Pollutants Around Industrial Parks in Context of Rural Revitalization

工业园区数量增多进而造成的有毒化学物质的排放,对生态系统和物种多样性造成不可逆转的损害。将西安市作为研究区域,并对区域概况展开分析,采用经验正交分析法获得空气污染物的时间分布特征,通过反距离权重法分析空气污染物的空间分布特征。根据上述特征分析了工业园区周边空气污染物浓度分布影响因素,以此获得了空气污染物的月、季变化特征,并绘制了污染物空间分布图,完成工业园区周边空气污染物浓度分布测定。分析结果表明,所提方法可以准确测定工业园区周边空气污染物浓度分布情况,具有较高的精度。

The increase in the number of industrial parks leads to the discharge of toxic chemicals,which can easily cause irreversible damage to ecosystems and species diversity.Taking Xi'an as the research area,this paper analyzes the regional overview.It uses empirical orthogonal analysis to obtain the temporal distribution characteristics of air pollutants,and uses inverse distance weighting method to analyze the spatial distribution characteristics of air pollutants.Based on the above characteristics,the influencing factors of the concentration distribution of air pollutants around the industrial park were analyzed,and the monthly and seasonal variation characteristics of air pollutants were obtained.A spatial distribution map of pollutants was drawn to complete the measurement of the concentration distribution of air pollutants around the industrial park.The analysis results indicate that the proposed method can accurately measure the concentration distribution of air pollutants around industrial parks,with high accuracy.
