摘要

摘要: 武汉城市圈的高时空分辨率大气细颗粒物(PM_2.5)排放清单研究的暂时缺乏，制约着区域PM_2.5污染的精确模拟和防控. 本研究采用排放因子法，融合高德地图兴趣点数据以及人口、路网和土地利用类型等代用指标，构建了2017-2023年该区域人为源排放PM_2.5的高空间分辨率（1 km×1 km）的排放清单，评估其不确定性，揭示其时空演变规律. 结果表明，武汉城市圈PM_2.5排放总量在2018年达峰值（164.59千吨），2020年因疫情降至137.15千吨，2023年反弹至149.97千吨. 各源类排放PM_2.5的不确定性为-31.7%～42.2%，化石燃料燃烧源（-13.2%～35.8%）和工艺过程源（-15.2%～34.3%）不确定性较高，扬尘源不确定性最低（-8.2%～15.4%）. 工艺过程源和扬尘源为主要贡献源，占PM_2.5总排放的46.5%～52.6%和26.7%～31.8%. 区域内PM_2.5排放强度在城市中心区为600～800 t/km²，是郊区、农村区域排放强度的40～50倍. 本研究可为大气化学数值模拟精度改进提供可靠的高精度清单数据支撑.

Abstract: The lack of high spatio-temporal resolution emission inventories for atmospheric fine particulate matter (PM_2.5) in the Wuhan Metropolitan Area limits the accurate simulation and control of regional PM_2.5 pollution. In this study, the emission factor method was adopted, integrating point of interest data from Amap as well as relevant allocation index including population, road network and land use type, etc., to construct a high-spatial-resolution (1 km×1 km) emission inventory of anthropogenic PM_2.5 emissions in the region from 2017 to 2023. Its uncertainty was evaluated, and its temporal and spatial evolution patterns were revealed. Results showed that the total PM_2.5 emissions peaked in 2018 at 164.59 kt, dropped to 137.15 kt in 2020 due to the pandemic, and rebounded to 149.97 kt in 2023. The uncertainty of PM_2.5 emissions from various source categories ranged from -31.7% to 42.2%, fossil fuel combustion sources (-13.2% to 35.8%) and process sources (-15.2% to 34.3%) have high uncertainty, while dust sources have the lowest uncertainty (-8.2% to 15.4%). Industrial and dust sources were the main contributor, accounting for 46.5% ~ 52.6% and 26.7% ~ 31.8% of total PM_2.5 emissions, respectively. The emission intensity of PM_2.5 in urban central area was 600 ~ 800 t/km², which was 40 ~ 50 times that in suburban and rural areas. This study can provide reliable high-precision emission inventory data support for improving the accuracy of atmospheric chemistry numerical simulations.
