Abstract: Based on the test results of sediment pollen, micropalaeontological identification and age of ZK13 core in the Pearl River Delta, the authors divided the palaeoenvironmental record information of the drilling section into four stages. Ⅰ: 91.50±11.00~84.61±5.47ka, the pollen assemblage is composed of trilete spore-Quercus-Poaceae- Castanopsis-Pinus-Castanea-Euphorbiaceae, reflecting a warm and humid climate, and there are no fossils of foraminifera and ostracods, indicating a continental sedimentary environment. Ⅱ: 84.61±5.47~59.46±3.02ka, the pollen assemblage is Castanopsis- trilete spore- Quercus- Poaceae- Castanea- Caryophyllaceae-monolete spore, reflecting a dry and warm climate, and there are no fossils of foraminifera and ostracods, indicating a continental sedimentary environment. Ⅲ: 59.46±3.02~2ka, the concentration of pollen is low; there are mainly spores and pollen of tree plants. It can be divided into three subzones, the climate is generally warm and humid. The content of micropalaeontology is high, the abundance of benthic foraminifera is much higher than that of ostracods, presumably it is sedimentary environment of transitional facies from sea to land. Ⅳ: 2000~1000a, spore has the highest content. The percentage of pollen of tree and herbaceous is reduced, the climate is more moist than phase III. The micropalaeontology is mainly ostracods. Based on assemblages and number of fossils, presumably it is a sedimentary environment of transitional facies from sea to land.
