| 摘 要： | 对东南极大陆沿海西福尔丘陵 ( Vestfold Hills,68°38′S,78°0 6′E)若干主要湖泊及其周边环境进行了现代生态学和古生态学研究。分析了不同类型湖泊的地理地貌环境和理化要素的动态特征、生态群落结构类型。利用湖岸古化石的生态组成与放射性同位素测定资料 ,推断了晚更新世以来随着全球海平面变化 ,该地区所经历的海侵、海退及其地理地貌改变过程 ,尤其重现了本区 1 80 0 0年以来因两次海侵而发生的湖泊生态演替过程。本文首次推出了该区海成湖泊 4种环境演化模式 ,认为这些湖泊环境演化模式不仅是区域环境生态历史演变的缩影 ,而且也是现今南极局部环境变化和全球气候变化的具体反映 |

| Abstract: | Ecological and palaeoecological studies were carried out in coastal lakes and adjacent areas in the Vestfold Hills (VH,68°38′S,78°06′E) at the Antarctic continent. Dynamics features of environmental geomorphology and physic chemical,the types of biological structures as well in those different lakes were analyzed. Marine macrofossils collected from terraces surrounding these lakes have radiocarbon ages from the Late Pleistocene were used for representing of evolutionary processes and models of the lakes after sea level changes and transgressions since 18000BP. It could be regarded as not only the history of environmental and ecological changes in VH coastal lakes,and also the reflection of local environmental change in Antarctic region and global climate changes in present time. |
| Keywords: | sea level change Antarctic continent environment of the lakes ecological evolution |
