| 摘 要： | 基于可获取的城市SO2和CO2排放清单数据，从数据挖掘的角度去探究两者排放趋势的相似性或差异性，分析这种趋势之间的相互关系对预测CO2今后趋势的借鉴意义。利用DTW算法实现SO2和CO2在时间轴上的匹配关系，将城市按照滞后型、同步型、超前型进行分类，对于各类城市进行碳达峰年预判，最后根据研究结果对碳减排行动提出了建议。

| Abstract: | Based on the available urban SO2 and CO2 emission inventory data, from the perspective of data mining, we explored the similarities and differences between the two emission trends and found out the reference significance of analyzing the relationship for predicting the CO2 emission trends. DTW algorithm was used to realize the matching pattern of CO2 and SO2 on the time axis. Cities were classified as lag type, synchronous type and advanced type, based on DTW. The carbon emission peak year of cities were estimated due to emission path types. At last, suggestions were proposed for future carbon emission reduction of the cities. |
