摘要
根据第二次土壤普查和2005年土壤采样分析结果,对聊城市20余年来土壤有机碳储量动态变化状况进行了研究,结果表明,研究区土壤有机碳总量增加了123万t。在此基础上进一步分析了土壤有机碳储量增加的原因。
It is of great importance to study the dynamic change of organic carben storage in agri- cultural soil. Based on the data of second soil survey and samples taken in 2005, the change of soil organic carben storage in Liaocheng city was analyzed.
