摘要:

利用河南省西部、南部山区13个县区的34个空气负氧离子站监测数据和中分辨率成像光谱仪(MODIS,moderate resolution imaging spectroradiometer)植被指数产品数据,使用相关分析、随机森林回归模型等方法,分析了影响河南省山地空气负氧离子浓度的主要气象因子和环境因子,并建立预测模型。结果表明,影响河南省山地负氧离子浓度日变化的主要气象因子是温度和相对湿度,主要环境因子是PM2.5浓度、PM10浓度和植被覆盖。通过建立负氧离子浓度预测模型,实现了负氧离子预报的定量化,为地区空气质量评价提供参考。

Abstract:

Using the monitoring data of 34 air negative oxygenion stations and Moderate Resolution Imaging Spectroradiometer vegetation index product data of 13 counties in the western and southern mountainous areas of Henan Province, correlation analysis and random forest regression model were used to analyze the main meteorological and environmental factors affecting the concentration of negative oxygenion in these areas to establish a negative oxygenion concentration forecasting model. Results showed that temperature and relative humidity were the main meteorological factors affecting the diurnal variation of negative oxygenion concentration, concentration of PM2.5, PM10 and vegetation coverage were the main environmental factors.By establishing the negative oxygen ion concentration forecasting model, the quantification of negative oxygen ion prediction was realized. This study provides reference for regional air quality evaluation.

Key words: negative oxygenion, meteorological factor, environmental factor, forecast model
