测定了洱海沉积物中有机碳、氮,提取了沉积物中的DNA.有机碳氮呈现相同的变化趋势:降解主要发生在表层10cm;7cm前后氧化-还原条件变化,微生物电子受体改变,所以有机质的降解方式不同,出现不同的特征.利用分子生物学和地球化学相结合的方法,能更全面的认识和理解早期成岩过程. |

The contents of organic carbon and nitrogen were measured and DNA was extracted in the sediments of Lake Erhai. The distribution of organic carbon and nitrogen is consistent, i. e. degradation of organic carbon and ni-trogen occurred in 10cm surface sediments and the modes of degradation change at 7cm, resulting in die different characteristics. Using the methods of molecular biology connecting with geochemistry, diagenesis process can be un-derstood deeply. |
