Shuitu Baochi Xuebao, 2017 以两种常见的有机废弃物牛粪和稻秆为原料，利用Eisenia foetida生产蚓粪，采用室内培养试验，研究了蚓粪在重金属污染的酸性土壤中对有机碳含量和形态、土壤酸度及Cu、Pb形态的影响。结果表明：在2.5%～10%的蚓粪用量下，土壤总有机碳含量增加了25%～83%，除牛粪蚓粪组的可溶性有机碳显著高于稻秆蚓粪外（P＜0.05），其余形态两种蚓粪间土壤有机碳含量无显著差异。蚓粪使土壤pH（H2O）值提升0.38～1.13个单位，同时交换性氢和铝的含量分别降低41%～77%和57%～94 ...

亚热带红壤区自然恢复草地转换为人工林后对土壤团聚体有机碳周转的影响
Shuitu Baochi Xuebao, 2019 选择江西泰和红壤退化区25年的自然恢复草地和2种恢复林地，测定了土壤团聚体有机碳的δ13C，探讨了森林恢复过程有机碳在团聚体中的分配和周转特征。结果表明：3种植被恢复模式土壤大团聚比例最高，微团聚体比例最低，木荷林0-20 cm土层大团聚体比例平均值高于马尾松林和草地；木荷林表层土各粒径团聚体有机碳含量均显著高于草地，表层土粉黏粒（

Shuitu Baochi Xuebao, 2022 为了科学评估中国退耕还林工程的固碳能力，收集整理了退耕还林一期工程（1999—2010年）详细的造林资料，结合中国主要树种的蓄积量（生物量）生长曲线和退耕还林前后土壤有机碳变化特征及各树种碳储量计算的相关参数，估算退耕还林工程1999—2050年的固碳量及其变化。结果表明：截至2010年，退耕还林工程造林总固碳量（土壤和植被）为355.87 Tg；工程实施期间，造林后期固碳量显著大于造林前期，平均每年固碳量为29.66 Tg；工程林固碳增汇潜力不断增加，预计到2050年中国退耕还林工程的固碳增汇潜力为1
