摘要/Abstract

摘要： 为提高网格化排放清单精度,结合AOD(aerosol optical depth)和标准路长提出基于AOD修正系数的空间分配模型,并以青岛市为例进行验证。验证结果表明:基于AOD修正系数的空间分配模型获取的2019年青岛市1 km×1 km分辨率的PM_2.5排放清单与测量数据的相关系数R2为0.55,高于基于标准路长、GDP(gross domestic product)和人口密度的空间分配模型(R2分别为0.47、0.43和0.31);青岛市中心城区,下辖的即墨、胶州、莱西、平度的中心城区及胶州湾地区是机动车的高排放区。本研究首次将强现实性的遥感数据引入空间分配模型,使每个网格的空间分配系数由固定值变为随真实大气污染状况变化的动态参数,提高了网格化机动车排放清单的精度,对研究机动车排放对大气污染的影响、精细化管控等具有重要意义。
