摘要:

固碳释氧是湿地最重要的生态系统服务之一。为了科学评估吉林省湿地生态系统固碳和释氧能力,以更好地保护湿地,采用实测生物量数据、湿地小班数据、TM遥感数据及相关统计数据,通过遥感反演、碳税价值法、市场价值法等方法进行估算,评估吉林省湿地生态系统固碳和释氧的服务功能。结果表明,吉林省湿地生态系统年固碳量为87.09×104 t,年释氧量为35.97×104 t,表现为较强的碳汇。各地区年固碳释氧能力以白城市和松原市较高,辽源市、通化市及四平市湿地年固碳释氧能力相对较低。在各湿地类型中,沼泽湿地年固碳量和年释氧量最高,分别为54.39×104 t和20.15×104 t;河流湿地年固碳量和年释氧量分别为17.62×104 t和8.52×104 t;人工湿地年固碳量和年释氧量分别为8.33×104 t和4.48×104 t,湖泊湿地年固碳量和年释氧量最小,分别为6.75×104 t和2.82×104 t。吉林省湿地年固碳释氧价值为105.5亿元,其中固碳价值为71.38亿元,释氧价值为34.12亿元。与第一次评估相比,吉林省湿地固碳释氧功能呈增加的趋势,西部地区湿地贡献率较大,其中季节性咸水沼泽和内陆盐沼固碳量和释氧量增加最为明显,湿地保护与恢复项目的建设和各大水利工程的实施可能是西部地区湿地固碳释氧能力增加的主要原因。继续加强对吉林省湿地的保护,有利于湿地生态系统充分发挥调节大气组分的能力。

Abstract:

Carbon sequestration and oxygen release is one of the most important services provided by the wetland ecosystem. In order to evaluate the carbon sequestration and oxygen release capacity of the wetland ecosystem in Jilin Province scientifically, and to protect the wetlands better, the biomass data, wetland survey data, TM remote sensing data and related statistical data are used in this study to evaluate through remote sensing inversion, carbon tax value method, and market value method. The results of the study show that the annual carbon sequestration of the wetland ecosystem in Jilin Province is 870900 t and the annual oxygen release is 359700 t. As for different areas, the annual carbon sequestration and oxygen release capacity of the wetland in Baicheng and Songyuan is higher, while it is relatively lower in Liaoyuan, Tonghua and Siping. Among the different wetland types, the annual carbon sequestration and annual oxygen release are highest in the marsh with 543900 t and 201500 t respectively, they are 176200 t and 85200 t respectively in the riverine, they are 83300 t and 44800 t respectively in the constructed wetland, and they are lowest in the lacustrine with 67500 t and 28200 t respectively. The value of annual carbon sequestration and oxygen release of the wetland in Jilin Province is 10.55 billion yuan with 7.14 billion yuan and 3.41 billion yuan respectively. Compared with the first assessment, the carbon sequestration and oxygen release functions of the wetland in Jilin Province are increasing, and the contribution of the wetland in the western area is higher. The carbon sequestration and oxygen release quantities in the seasonal marine swamp and the inland marine swamp increase most obviously. The wetland protection, the construction of restoration projects and the implementation of major water conservancy projects may be the main reasons for the increase in the carbon sequestration and oxygen release capacity of the wetland in the western area. Therefore, the continued strengthening of the wetland protection in Jilin Province will help the wetland ecosystem to full play its ability to regulate atmospheric components.
