摘　　要：通过对湛江湖光岩玛珥湖钻孔孢粉记录的研究认为 ,末次冰期以来 ,该区植被类型从早期的南亚热带季风常绿阔叶林依次演替为 ,中亚热带常绿、落叶阔叶林→南亚热带季风常绿阔叶林→中亚热带常绿 落叶阔叶 针叶混交林 (湖边草地 )→热带季雨林→半常绿季雨林。气候最寒冷的时期温度比目前至少降低了 4— 6°C以上。全新世早期相对干旱。A new pollen record from the Huguangyan Maar Lake (110°17′E,21°9′N ) in the Leizhou Peninsula, Guangdong Province, China, provides information on vegetation and climate changes since the last glaciation. Six major significant changes in pollen associations indicate the history and the process of vegetation successions, those are the southern subtropical evergreen monsoon forest, middle subtropical evergreen and deciduous broad-leaved forest, southern subtropical evergreen monsoon forest, middle subtropical evergreen-deciduous broad-leaved and conifer mixed forest, tropical seasonal rain forest, and the semi-evergreen seasonal rain forest. The pollen record suggests that the temperature dropped 4—6 °C during the coldest epoch of the last glaciation than that of today. The climate in early Holocene was drier in this region.
