    摘要:

    河湖相沉积物上发育的昆山大市镇土壤位于太湖地区,形成于1万年以前。根据土壤特性,沉积—成土作用阶段,放射性碳年龄以及孢粉和微形态分析,该土壤可划分为四个层段。土壤层段特性的变化反映出这里全新世自然环境的变迁和人为活动在土壤中留下的不可磨灭影响,尤为强调的是这里水稻栽培有着悠久的历史。

    Abstract:

    The soils on fluviolacutrine deposit,in Kunshan region,South Jiangsu,formed in the Holocene.According to the analysis of their soil properties,14C age and pollen spectrum,and micromorphology the soils of Holocene can be divided into four forming stages: initial,transitional and typical ones of deposition soil formation,as well as forming stage of modern cultivated soils.The four forming stages are consistent with early Holocene,the beginning of mid-Holocene,optimum mid-Holocene and late Holocene.At the same time,they reflect changes in the environment during the Holocene including climate change,and vegetation evolution under intensive cultivation of human.It should be emphasizld that rice cultivation here has a log history.
