湿地是地球上单位面积生态系统服务价值最高的生态系统类型,其中湿地生态系统的固碳功能和物质循环、气候变化等生态学热点问题紧密相关。科学直观的展现湿地生态系统固碳功能一方面有助于公众理解其价值,另一方面也可以为国家推进“碳达峰”和“碳中和”进程提供数据支撑。基于前期研究结合文献分析,本文系统梳理了我国典型内陆和滨海湿地生态系统的固碳价值及其分异规律。结果发现内陆湿地生态系统单位面积的固碳价值范围为1400~43360元/(hm2·a),滨海湿地生态系统单位面积的固碳价值相比内陆湿地变化幅度较小,均值为4880.57元/(hm2·a)。滨海湿地生态系统固碳价值在总生态系统服务价值的占比(最低为10.72%,平均值为13.19%)明显高于内陆湿地中的占比(最高为若尔盖沼泽湿地的10.08%)。研究结果可为湿地生态系统保护、修复和管理提供一定的科学支撑。 |

Wetlands have the highest ecosystem service value on earth per unit area. Carbon sequestration is among the most valuable of ecosystem services, and closely related to nutrient cycling and climate change. In this study, typical inland and coastal wetlands in China were studied, and we determined carbon sequestration values among the different wetland types, their proportional contributions to wetland ecosystem services, and then systematically analyzed carbon sequestration values and the differentiation rules of different wetland ecosystems. We also explored the factors affecting carbon sequestration in wetland ecosystems. Our analysis was based on Landsat TM 5 remote sensing images from 2011 and research on wetland carbon sequestration values conducted by our team and other relevant research. The spatial differentiation of carbon sequestration values in wetland ecosystems was significant and the variation in the values among inland wetlands was higher than that among coastal wetlands. The annual carbon sequestration value of inland wetlands per unit area was in the range of 1 400-43 360 yuan/hm2, with the highest value in Taihu Lake wetland (43 360 yuan/hm2), followed by the Zoige wetland (19 990 yuan/hm2), and the lowest value was in Baiyangdian wetland (1 400 yuan/hm2). The proportion of carbon sequestration value to total service value was highest in the Zoige wetland (Sichuan) at 10.08%, while the proportions in Caohai wetland (Guizhou), Dongting Lake wetland (Hunan), the Baiyangdian wetland (Hebei), Bosten Lake wetland (Xinjiang), and Qinghai Lake wetland (Qinghai) were less than 1%. The annual carbon sequestration values of coastal wetland ecosystems per unit area were in the range of 3 711.50-6 448.00 yuan/hm2, with an average value of 4 880.57 yuan/hm2. The proportions of carbon sequestration value to total ecosystem service value for the coastal wetlands (minimum 10.72%, average 13.19%) was significantly higher than those of inland wetlands. To enhance the carbon sequestration function and value of wetland ecosystems, we recommend strengthening protection of wetland soils, particularly in coastal wetlands. Our research provides scientific support for the protection, restoration and management of wetland ecosystems. |
