    FOSSIL DIATOMS IN NO.47 BOREHOLE OF JIANGHAN PLAIN AND THEIR SIGNIFICANCE TO PALEOENVIRONMENTAL ANALYSIS
    江汉平原47号钻孔中的化石硅藻及其在古环境分析上的意义
    Tentative Application of the CLSM Technique to the Study of Fossil Diatom Microstructure
    CLSM技术应用于化石硅藻微构造的尝试研究
    In the present paper, one new fossil diatom species, Geissleria jianghanensis sp. nov. Li, is described.
    在对江汉平原钻孔中属晚更新世地层的化石硅藻进行鉴定时,发现1个新种:Geissleria jianghanensis sp.nov.
    According to these diatom-pH transfer functions,the fossil diatom in the sediment were analysed to reconstruct the pH value in Llyn Hir(lake) from 1956 to 1995.It showed that the improvement of pH in 1985 was the result of liming by the history record and there was an obvious effect in the following six years but the effect weakened gradually and vanished.
    我们在Llyn Hir湖中心钻取岩芯,对顶部14.5cm进行了化石硅藻种群组合的分析,利用这些资料,根据这3个硅藻-pH转换函数模型,定量重建了该湖1956~1995年pH的变化过程. 结果显示,1985年为了改善该湖酸化状况,向湖中施加石灰引起湖水pH明显增高,这种显著效果维持了6年,此后逐渐减弱乃至消失.
