里下河地区全新世自然环境变迁OA北大核心CSCDCSTPCD
Holocene environmental changes in Lixiahe area
在区域地质调查项目进行过程中,以几个典型地质剖面和钻孔为基础,讨论了里下河区域全新世地层的分布规律,研究了地貌分布特征;探讨了全新世古植被、古气候与古环境变迁以及历史时期自然环境变化特征.里下河地区全新世自然环境变迁经历了4个重要的阶段:(1)10～7.5 kaBP,以湖沼发育为主,海水曾经影响到本区；(2)7.5～4.0kaBP,海水入侵本区,自然环境以潮滩、滨浅海、潟湖等为主,最大海侵甚至可到达运河以西地区,但里下河仍然有部分地区未被海水淹没…查看全部>>
During the performance of the regional geological survey project, the authors, based on several typical geological profiles and drill holes, discussed the distribution regularity of Holocene strata and studied the distribution characteristics of landform in Lixiahe area. Then the vegetation change and palaeoclimatic and palaeoenvironmental variations in the area since 10 ka BP were analyzed and investigated. According to the results obtained, the natural env…查看全部>>
