基于生态人文理念的对环境污染时空分布特征研究

Study on the Spatiotemporal Distribution of Environmental Pollution Based on Ecological Humanities

研究基于生态人文理念的对环境污染时空分布特征,利用广东省2018年全年空气质量指数,通过趋势分析方法、SURFER软件以及灰色关联分析方法研究基于生态人文理念的广东省环境污染时空分布特征。研究结果表明,广东省21个城市中空气质量最高与最低城市分别为汕尾市以及广州市;广东省空气污染物浓度较高与较低月份分别为1、2月份以及7、8月份;造成广东省环境污染主要大气污染物为细颗粒物、可吸入颗粒物;与环境污染关联较大的气相因素为降雨量以及相对湿度,降雨量增加可缓解环境污染,相对湿度越高环境污染越严重。

Guangdong Province's 2018 annual air quality index for fine particles,respirable particles,sulfur dioxide,and nitrogen dioxide were studied by using trend analysis method,SURFER software,and grey correlation analysis method.The results show that the highest and lowest air quality among the 17 cities in Guangdong Province are Shanwei City and Guangzhou City;the higher and lower air pollutant concentrations in Guangdong Province are January,February,and July and August,respectively.The main atmospheric pollutant of environmental pollution in Guangdong Province is PM10.The gas phase factors that are greatly related to environmental pollution are rainfall and relative humidity.Increased rainfall can alleviate environmental pollution.The higher the relative humidity,the more serious the environmental pollution.
