摘要
在湖泊沉积物实验方法基础上 ,初步建立了泥炭中硅藻的提取方法 ,并利用扫描电镜在金川泥炭中首次发现了硅藻 ,根据其形貌特征确定了科属 ,发现研究区硅藻以生活在浅淡水中的舟形藻科为主 ,该类硅藻可能具有一定的季节意义。
On the basis of the methods applied to lake sediments, a new method of extracting diatoms from peat has been developed. Diatoms in Jinchuan peat were first found by SEM, and the species of diatoms were identified according to their configurative characters. It is found that Naviculaceae, which exists in flat and fresh water, is the dominant species and this kind of diatoms perhaps may have some seasonal implication.
