摘要
将有序样品最优分割法引入孢粉学研究之中，以杭州湾北部沿岸某钻孔晚第四纪沉积物为例，从中划分出五个孢粉带，并讨论了与之相应的地层时代与沉积环境，同时对影响这一方法所得结果的因素作了分析．
It is successful in this paper that the best division of ordinal samples has been used to distinguish five spore-pollen zones from a core of Quaternary in northern Hangzhou Bay. The caculation processes is as follows: 1 ) list target Kmatrix; 2) caculate distance factor D and list D matrix ; 3) caculate (n) and list S matrix and I matrix showing the sample number of each best division. Besides, some problems about the application of this mathimatical method in Palynology are dicussed detailedly and satisfactory results are attained.
