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.

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

As an applied technology in modern ecology research,stable isotope technique has been prosperously applied to the ecological fields.Because stable isotope ~(15)N technique can trace and distinguish the source and fate of nitrogen matters,and it plays a very important role in the research on nitrogen cycling in natural ecosystems.This paper firstly summarizes,mainly from the processes of input,transformation and fate,the advance in current research on the biogeochemical process of nitrogen in wetland based on...

As an applied technology in modern ecology research,stable isotope technique has been prosperously applied to the ecological fields.Because stable isotope ~(15)N technique can trace and distinguish the source and fate of nitrogen matters,and it plays a very important role in the research on nitrogen cycling in natural ecosystems.This paper firstly summarizes,mainly from the processes of input,transformation and fate,the advance in current research on the biogeochemical process of nitrogen in wetland based on stable isotope ~(15)N technique.Then it analyzes the issues existed in current research,and points that,in particular,the current research is still very weak,and lacks systemic,deep and broad study.Finally,this paper forecasts the prosperous application of this technique in the research on the biogeochemical process of nitrogen in wetland,and indicates that its application will promote the depth of wetland quantitative research and contribute to the development of wetland science in China.

稳定性同位素技术是现代生态学研究中的一门应用技术,它几乎在生态学研究的各个领域都有着广泛的应用。其中15N技术由于具有示踪和区分氮素物质的源与去向等优越性而在生态系统氮循环研究中发挥了极为重要的作用。文章主要从湿地氮素的输入过程、转化过程以及归趋过程三方面综述了该技术在当前国内外湿地氮素生物地球化学过程研究中的应用进展,特别指出当前基于该技术的湿地氮素生物地球化学过程研究尚缺乏一定的系统性、深入性和广泛性。最后,文章就该技术在湿地氮素生物地球化学过程研究中的应用前景进行了展望研究。

Polycystine radiolarians play an important role in the research of paleoceanography and paleoenvironment because of their indiscerptible siliceous skeletons and the good corresponding relation between radiolarian assemblage and physical oceanography,hydrographical conditions.With widespread radiolarian application in paleoceanography reconstruction and the improvement of research measures,living radiolarians have been widely studied in the world.China has participated in such deep-sea research programs as IODP,which...

Polycystine radiolarians play an important role in the research of paleoceanography and paleoenvironment because of their indiscerptible siliceous skeletons and the good corresponding relation between radiolarian assemblage and physical oceanography,hydrographical conditions.With widespread radiolarian application in paleoceanography reconstruction and the improvement of research measures,living radiolarians have been widely studied in the world.China has participated in such deep-sea research programs as IODP,which should accelerate the step of the study of paleoceanography.Radiolaria is an important fauna among the marine micropaleontology,whose ecology knowledge is the base of paleoceanographical and paleoenvironmental reconstruction.Therefore,it is very necessary to offer the latest achievement and progress trends in ecological studies on living radiolarians to research communities,with a view to making our research on radiolarian keep pace with the world and offering more proxies of paleoenvironment and paleoceanography.

放射虫以其不易溶解的硅质壳体在古海洋、古环境研究中起着不可替代的作用,其种类组合与海洋物理、水文环境有着很好的对应关系。随着放射虫在古海洋环境研究中的广泛应用以及研究手段的改进,放射虫现代生态学研究在世界各大洋得到了广泛开展。中国加入综合大洋钻探计划,势必会加快我国古海洋学的研究步伐,放射虫作为海洋微体古生物中的一个重要类群,其生态学知识是重建古海洋、古环境的基础。因此,有必要向我国学术界提供放射虫现代生态学的研究成果及最新发展趋势,促使我国放射虫的研究与国际接轨,以提供更多的古海洋、古环境替代性指标。
