摘要
本文是在大九湖盆地,沿盆地地表横剖面样线进行的表土孢粉分析。结果表明:现代孢粉组合基本上反映了当地的植被状况,尤其是盆地中心的部位的样品。但在无松样点,松花粉以较大比例出现;大量箭竹丛下无箭竹花粉。同时,用外加花粉法求得花粉浓度,并与花粉百分比计算相比较,二者表现为基本一致的变化趋势,但前者更为明显。
Fifteen surface samples from a transect from one side (mountain) across a swamp basin to another side in Dajiuhu area, Shennongjia Mountain, were analysed and compared with modern vegetation in this paper. The results show that the pollen assemblage in this area can reflects the vegetation types basically, but there are some difference between them. For example, the pollen of Pinus reached 10% where is no any Pinus plant, but the sites exiting Sinarundiaria nitida had not its pollen. Meanwhile, the pollen frequency were calculated by means of exotic pollen (Lycopodium) , and compared with pollen percentage. It shows that the fluctuation of them are similar, but the former are more obvious than the later.
