Based on soil under seven vegetation types, the carbon sequestration potential in the Ebinur Lake wetland was estimated using the maximum value method, the saturation value method, and the classification and grading method. Results indicated that: 1) Soil carbon sequestration results for the top 20 cm soil layer were about 1.88 Mt using the maximum value method; the middle level standard of the classification and grading method result was 1.71 Mt. 2) Soil carbon sequestration potential in the top 20 cm layer under different vegetation types, evaluated using the saturation value method and the classification-grading method, ranged from 0.45 to 0.67 Mt, accounting for about 5/16 of the ideal carbon sequestration potential. 3) Carbon sequestration potential calculated using the saturation method and the classification method (middle level standard), combining the soil organic carbon increment under different vegetation types in Ebinur Lake wetland, recorded an average growth rate of soil organic carbon around 0.7–1 kg/(hm²·a). Time required to reach its carbon sequestration potential was 41 to 144 a. These results indicate that soil organic carbon content dynamically changes, and different forms of land use affect soil organic carbon content. The potential and ability of soil carbon sequestration and its mechanism of dynamic change are investigated, providing a scientific basis for understanding regional carbon cycle and climate change in wetlands.

艾比湖湿地土壤固碳潜力三种估算方法的比较与分析

基于七种植被类型下的土壤，使用最大值法，饱和度法和分类分级法估算了艾比湖湿地的固碳潜力。结果表明：1）采用最大值法，表层20 cm土层的固碳量约为1.88Mt。分类和定级方法结果的中级标准为1.71Mt。2）使用饱和度法和分类-分级法评估的不同植被类型下最顶层20 cm层的土壤固碳潜力为0.45至0.67 Mt，约占理想固碳潜力的5/16。3）使用饱和法和分类法（中级标准）计算出的固碳潜力，² ·a）。达到其碳固存潜力所需的时间为41至144 a。这些结果表明，土壤有机碳含量是动态变化的，不同形式的土地利用都会影响土壤有机碳含量。研究了土壤碳固存的潜力和能力及其动态变化的机理，为了解湿地的区域碳循环和气候变化提供了科学依据。
