摘　　要：甘肃省作为中国重要的生态屏障,省内尕海湿地是国际重要湿地之一,研究尕海湿地能源抵消效应对甘肃省更好地实现“双碳”目标和维护生态安全具有重要意义。根据尕海不同类型湿地的占地面积、土壤的有机碳密度计算出尕海湿地的碳储存总量,以及通过部门法计算出甘肃省2021年不同行业能源消耗的碳排放总量。结果表明,尕海湿地能源抵消效率呈现出明显的类型差异,草本泥炭地和高山湿地的抵消效率相近,永久性沼泽湿地的能源抵消能力最低。因此,针对提升尕海湿地能源抵消率提出以下建议:改良湿地相关的计算方法、完善湿地保护政策、拓宽融资渠道、保护湿地资源,提升抵消能力和提升专业水平,增强环保意识。Gansu Province is an important ecological barrier in China,the Gahai wetland in the province is one of the important wetlands in the world,the study of the energy offset effect of Gahai wetland is of great significance to better achieve the dual carbon goal and maintain ecological security in Gansu Province.The article calculates the total carbon storage of Gahai wetland based on the area of different types of wetlands and the organic carbon density of the soil,and the total carbon emissions from energy consumption of different industries in Gansu Province in 2021 were calculated through the sectoral method.The results showed that there were obvious types of energy offsetting efficiency in Gahai wetland,with similar offsetting efficiency between herbaceous peatland and alpine wetland,and the lowest energy offsetting capacity in permanent swamp wetland.Therefore,the following suggestions are put forward to improve the energy offset rate of Gahai wetland:improve the calculation method related to wetlands,improve wetland protection policies,broaden financing channels,protect wetland resources,improve offset capacity and professional level,and enhance environmental awareness.
