摘要: 采用概率反演分析法估算黄土高原草地和农田生态系统各碳库滞留时间及固碳潜力。结果表明:除农田植物地上部分外,植物地上部分、地下部分、代谢性凋落物及土壤活性有机碳库滞留时间最短,为25~203 d;惰性凋落物碳库滞留时间为2.4~3 a;慢性有机碳库和惰性有机碳库滞留时间最长,分别为57.4~79.6 a和593~598 a。多年生草地的根系滞留时间显著高于农田;而农田代谢性凋落物碳库和慢性有机碳库的滞留时间显著高于草地。根据反演所得参数模拟,在当前气候和土壤条件下,农田和草地系统土壤有机碳在250 a左右时达稳定状态,农田系统固碳潜力约为2 680 g C·m-2,草地约为3 130 g C·m-2。农田有机肥的输入能使土壤有机碳多固定4 000 g C·m-2。有机肥的输入及土壤有机碳周转缓慢使耕作农田比草地更有利于土壤有机碳积累。

Abstract: A Bayesian probability inversion was applied to estimate the Carbon residence times and sequestration potential of grassland and cropland ecosystems in the Loess Plateau. The result shows that the shortest Carbon residence times ranged from 25 to 203 days were in the aboveground and belowground biomass pools, the metabolic litter pools and the active soil organic matter (SOC) pools, excluding the aboveground biomass pool in cropland. The structure litter pools had Carbon residence times between 2.4 and 3 years. The longest Carbon residence times were 57.4-79.6 years and 593-598 years in the slow and passive SOC pools, respectively. Carbon residences times for the belowground biomass pools were longer in grassland than those in cropland, whereas Carbon residences times in the metabolic litter and slow SOC pools in grassland were shorter than those in cropland. According to the parameters derived from the inversion model, the SOC pools in grassland and cropland would reach a stable state in 250 years. The Carbon sequestration potential would be 3 130 and 2 680 g C·m-2, respectively, in grassland and cropland ecosystems. The application of manure could result in higher (4 000 g C·m-2) Carbon sequestration. Compared to that in grassland, the application of manure and the longer Carbon residence times of soil pools could lead to higher SOC sequestration in cropland ecosystem.
