摘　　要：为实现国家和城市尺度的“双碳”目标,落实减污减碳的总体要求,支持气候变化工作的成效评估,开展碳监测和评估试点工作非常重要.本研究以受海陆交互影响的滨海城市—深圳为例,基于基础地理数据、经济社会数据、排放数据、气象站数据和FNL再分析数据,采用WRF、HYSPLIT、FLEXPART-WRF、SAFE-C等模型,发展了一套适应于典型海陆交互区城市高精度温室气体监测网建设的科学选址方案.通过对各个模型结果进行整合分析,表明优选监测点位贡献度均在90%以上,均具有较高敏感性(平均敏感性为95.6%).本方案选取的温室气体监测点组成的温室气体监测网络能够满足深圳市反演1 km分辨率格网化温室气体源汇的目的.本文报道的科学选址方法对海陆交互滨海城市温室气体监测网建设具有参考和指导意义.In order to achieve carbon emission summit and carbon neutrality target at the national and city-scales,to coordinately reduce air pollution and carbon emission,and to evaluate the effectiveness of climate change adaptation policies and activities,it is important to carry out a carbon monitoring and assessment pilot program.This study takes Shenzhen as an example,to study how to design high precision greenhouse gas(GHG)monitoring network in coastal cities which affected by land-sea interaction.Based on basic geographic data,economic and social data,emission data,meteorological station data and FNL reanalysis data,a set of scientific site selection models,i.e.WRF,HYSPLIT,FLEXPART-WRF and SAFE-C were used to design a high-precision greenhouse gas monitoring network in a typical land-sea interaction city.A scientific site selection scheme was developed for costal cities.The integrated analysis of the results of each model shows that the contribution of the selected monitoring sites is above 90%,and the sensitivity is high(average sensitivity is 95.6%).The GHG monitoring network composed of the selected GHG monitoring towers can meet the purpose of inversion gridded GHG source sinks at a 1 km resolution in Shenzhen.The scientific site selection method reported in this paper has guiding significance for the construction of GHG monitoring network in sea-land interactive coastal cities.
