摘要
基于青藏高原生态环境保护的重要性,选取川西高原的康定市为研究对象,通过获取7-8月旅游旺季典型日的环境空气质量数据和组分数据,用人工智能聚类算法(ART-2a)和示踪离子法两种方法对颗粒物质谱数据进行分类查找污染源,同时用质谱法分析主要VOCs组分,得出康定市环境空气中的PM_(2.5)和O_(3)浓度主要受移动源和餐饮排放影响。
Based on the importance of ecological environmental protection in the Qinghai-Tibet Plateau,Kangding city in the western Sichuan Plateau was selected as the research object.By obtaining the ambient air quality data and component data of typical days in the tourist peak season from July to August,the particle mass spectrometry data were classified by artificial intelligence clustering algorithm(ART-2a)and tracer ion method to find the pollution sources.Meanwhile,the main VOCs components were analyzed by mass spectrometry,and it was concluded that PM_(2.5)and O_(3)concentrations in the ambient air were mainly influenced by mobile source and food and beverage emissions.
