| 摘 要： | 本文以宁夏水洞沟全新统剖面为例,运用孢粉浓度统计法对我国西北地区土类堆积物进行了初步研究,并与传统的孢粉百分比统计法所得结果进行了对比。文中,运用电子计算机进行了孢粉资料整理,划分出了七个孢粉组合带,基本上符合我国北方全新世气候变化的一般规律。结果表明,两种方法所反映的古植被、古气候变化趋势基本一致。在孢粉数量丰富的情况下,孢粉浓度统计在图式上表现得更突出和明显;在孢粉数量较少时,用百分比统计法更便于说明问题。

| Abstract: | Taking the Shuidonggou Pleistocene section in the Ningxia Province as an example, this paper discussed the ground accumulation in the west-northern area of Chiaa by using the statistical method of the sporo-pollen concentration and compared this result with the result obtained by the tranditional sporo-pollen percentage statistical method. In this paper ,according to the data obtained with an electronic computer,the whole section is divided into seven sporo-pollen sasociation zones,which accord basically with the universal law of the climate changes during the pleistocene epoch in the northern part of China. The result shows that the variational tendencies of the palaeoplant and the palaeoclimate mirrored by the both methods are basically the same. In the case of the sporo-pollen abundance the statististical method of the sporo-pollen concentration is puite prominent and clear in the diagram.While the amount of the sporo-pollen is becoming smaller, the statistical methgd of the sporo-pollen percenttge is more useful to answer these questions. |
