摘　　要：本文运用有序系统聚类、对应聚点、最优分割三种数学地质方法，参照孢粉图式将九龙江河口平原海澄ZK5孔剖面划分为8个孢粉带。结合其他钻孔有关资料，得出研究区9个综合孢极组合带，分别反映晚第四纪不同阶段的不同气候环境。通过对应分析结果表明，本区晚第四纪植被演替的决定因素中，湿度比温度更为重要。Using three methods of mathematical geology, namely constrained hierachy clustering,correspondirlg spotting and optimum segmentation, with references to the sporopollen di-agram, 8 sporopollen zones can be divided for Haicheng Core ZK5 in the Jiulongjiang Estuar-ine Plain. Based on the combined consideratiom of the data of other cores, 9 comprehensive sporopollen assemblage zones can be obtained, which reflect varied climatic environments of varied stages during Late Quaternary in the region, respectively, The results of corre-sponding analysls show that in the decisive factors of Late Quaternary vegetation evolution in the region, the moisture is more significant than temperature.
