| 摘要: |
| 以南京市为温室气体监测区域，以2021年1月和7月作为冬、夏季的代表，利用拉格朗日粒子扩散模型（LPDM）和K均值（K-Means）聚类算法对南京市已有的高塔点位进行筛选，研究温室气体监测点位布设最优位置。通过计算不同点位的城市CO2贡献度，最终确定了冬季和夏季各8个温室气体监测建议点位。结果表明，通过聚类算法筛选出的监测站点选址能对南京市大部分城区的温室气体排放具有相对最大的覆盖范围和较高的敏感性，能够有效反映出南京市CO2排放量的梯度变化，对南京市不同时空尺度上的温室气体排放达到相对最好的监测效果。 |

| Abstract: |
| In this paper，Nanjing was taken as the research object of greenhouse gas(GHG) monitoring work， we selected January and July 2021 as representatives of winter and summer and chose the existing high tower sites as research objectives，by using Lagrangian Particle Dispersion Model and K-means clustering algorithm，to evaluate the optimal GHG monitoring sites and then establish the GHG monitoring network in Nanjing. We calculated the contributions to the urban's CO2 concentrations of the different tower sites， and 8 recommended GHG monitoring sites were finalized in winter and in summer， respectively. The results show that the monitoring site selection screened by the clustering algorithm are high sensitivity to the greenhouse gas emissions and can cover most of the Nanjing city， which can effectively reflect the gradient change of the city's CO2 emissions， and achieve the best monitoring effect on Nanjing's greenhouse gas emissions at different temporal and spatial scales. |
