为使港口企业制定合理的碳达峰方案，首先，界定集装箱港口的测算范围，以船舶与集装箱为计量单位，建立基于能源消耗的集装箱港口作业碳排放量测算模型，采用考虑异常值的支持向量回归模型预测集装箱吞吐量；再通过测算模型得到碳排放量时间序列，并设计基于MannKendall趋势检验法的碳达峰时间判断标准，进而确定碳达峰时间；最后，以某集装箱港口为例，测算2000—2020年以及未来10年的碳排放量，得出该港的碳达峰时间，并提出有效降低港区碳排放量的建议.该方法可为港口制定碳达峰方案提供参考.

In order to enable port enterprises to formulate a reasonable carbon peak scheme, firstly, the calculation scope of container ports was defined, taking ships and containers as the measurement unit, a calculation model of carbon emissions from container port operations based on energy consumption was established, and the support vector regression model considering outliers was used to predict container throughput. Then the carbon emission time series was obtained by calculation model, and the judgment standard of carbon peak time based on Mann Kendall trend test was designed to determine the carbon peak time. Finally, taking a container port as an example, the carbon emissions from 2000 to 2020 and the next decade were calculated, the carbon peak time of the port was obtained, and some suggestions were puts forward to effectively reduce the carbon emissions of the port. This method can provide a reference for the port to formulate the carbon peak scheme.
