摘要
利用中国HJ-1环境星CCD影像,基于遥感技术采用非线性大气辐射传输6S模型,通过ENVI5.3 IDL编程实现吉安市悬浮细颗粒物(PM2.5)和可吸入颗粒物(PM10)时空分布特征遥感反演。研究表明:从时空位置来看,吉安市悬浮颗粒物AOD在工业发达,人口、交通密集城镇地区最为严重;从季相变化特征来看,吉安市AOD上半年优于下半年;从时间特征上来看,2011—2017年AOD浓度逐年下降,空气质量逐年提升。反演结果具有较高地实用价值,能为审计、环保等相关部门提供决策支撑。
Based on the Chinese HJ-1 environmental star CCD image,the 6S model of nonlinear atmospheric radiation transmission based on remote sensing technology was used to realize the spatial and temporal distribution of suspended fine particulate matter(PM2.5)and respirable particulate matter(PM 10)in Ji′an City through ENVI5.3 IDL programming.Feature remote sensing inversion.The research shows that from the perspective of time and space,the AOD of suspended particulate matter in Ji′an City is the most developed in the industry,and the population and traffic-intensive urban areas are the most serious.From the characteristics of seasonal phase change,the first half of Ji'an AOD is better than the second half;From 2011 to 2017,the AOD concentration decreased year by year,and the air quality increased year by year.The inversion results have high practical value and can provide decision support for auditing,environmental protection and other related departments.
