摘要
对江苏建湖地区若干全新世剖面进行了系统的孢粉分析，划分出６个孢粉组合带，恢复了本地区自早全新世以来的古植被演替与古气候古环境变迁。
Throuth the systematic polynological study of four sections in Jianhu county, Jiangsu province, six sporo pollen assemblages have been obtained, and the paleovegetation and paleoclimate since the Early Holocene in this area have been restored. The paleoenvironment changes and stratigraphical division during the Holocene in this area have been discussed. The spor pollen assemblages in Jianhu area can be divided into 6 zones, from bottom to top as follows: Zone A: Cupressaceae Pinus Betula Artemisia Gramineae sporo pollen zone revealing a cool and slightly dry climate in the Pre Boreal period. Zone B: Quercus Castanea Pinus Artemisia Chenopodiaceae sporo pollen zone revealing a temperate and semi moist climate in the Boreal period. Zone C: Quercus Castanopsis Castanea Typha Atriplex sporo pollen zone revealing a warm and moist climate in the Atlantic period. Zone D: Quercus Castanea Chenopodiaceae Artemisia Typha sporo pollen zone revealing a temperate and semi moist climate in the Sub Boreal period. Zone E:Chenopodiaceae Artemisia Gramineae Pinus sporo pollen zone revealing a temperate cool and slightly dry climate in the Sub Atlantic period. Zone F: Artemisia Typha Hydrocharitaceae Salvinia Pinus sporo pollen zone revaling a temperate cool and semi moist climate in the Sub Atlantic period.
