浙北嘉湖平原发育,深受全新世中,后期沉积环境所制约。本文以该区分布最广的四个水稻土土属(湖成白土田、黄斑田、小粉田、青紫泥田)为研究对象,从颗粒参数、孢粉微体古生物组合、矿物成分、粘粒矿物、~(14)C、古遗址等方面的测定、分析推断,把本区沉积环境类型概分为滨湖相、陆相、海陆交互相、湖沼相四类。再进一步把沉积环境与土壤发育联系起来研究,以揭示本区几种水稻土的分布规律、形成特点和基本属性。
The development of the Jiahu Plain in North Zhejiang is well controlled by the depositional environment in the middle and late Holocene. In this paper, the four most widely distributed paddy soils (Lake into white soil, macular, small powder field, Qing purple soil) as the research object, from the particle parameters, sporopollenic paleontology, mineral composition, Minerals, ~ (14) C, ancient ruins and other aspects of the analysis, inferred, the type of sedimentary environment in this area can be divided into Binhu phase, continental phase, sea and land interaction phase, lake phase four. Furthermore, the sedimentary environment and soil development are further studied in order to reveal the distribution characteristics, formation characteristics and basic attributes of several paddy soils in this area.
