The age measures and its layer sequence tratigraphy of Late Quaternary sediment in Lushan Dajiaochang of China

Through the scientific investigation on Lushan for a long time, detailed studies have been carried out on the geologic stratum section of Late Quaternary in Dajiaochang. The series age data of complete stratigraphic section and full time formation since 400 kaBP were based on the results of the analyses using the dating methods with various instruments such as the ancient geomagnetism, electronics spin resonance （ESR）, 36C1 and lumines- cence dating, etc. Corresponding to these data, it identified the paleomagnetic polarity events including Biwa- III event （320 kaBP）, Biwa- 1I event （260 kaBP）, Biwa- I event （180 kaBP, scarcity due to the disturbance of the iron dish）, Blake event （100 kaBP） and Laschamp event （20 kaBP, didn＇t grow due to the activities of the surface）, etc. Combined with the sequence stratigraphy, layer type characteristics and its sediment environment, the strati- graphic can be divided into 4 stages of development respectively ： Stage [ is the climate period of glacial epoch （200-400 kaBP）; stage 11 is the climate period of interglacial epoch （100-200 kaBP）; stage llI is the climate peri- od of periglacial epoch （10-100 kaBP）; stage IV is the climate period ofpostglacial epoch （0-10 kaBP）.

中国庐山地区大校场晚第四纪沉积年龄测定及层序地层学

通过庐山科学考察(1997—2009)对大校场沟口晚第四纪剖面地层进行精细研究,采用古地磁、电子自旋共振(ESR)、36Cl、释光法等多种仪器测年方法的分析,建立了完整剖面的全时段地层的自400 ka.B.P.以来的系列年龄数据,与之相对应识别出Biwa-III(320 ka.B.P.)事件、Biwa-II(260 ka.B.P.)事件、Biwa-I(180 ka.B.P.)事件(因铁盘扰动影响缺失)、Blake(100 ka.B.P.)事件、Laschamp(20 ka.B.P.)事件(因表层活动影响未发育)等古地磁极性事件,结合层序地层和层型特征及沉积环境将剖面地层由早至晚划分为4个发展旋回阶段:I阶段为冰期(400～200 ka.B.P.)气候时期,II阶段为间冰期(200～100 ka.B.P.)气候时期,III阶段为冰缘期(100～10 ka.B.P.)气候时期,IV阶段为冰后期(10～0 ka.B.P.)气候时期。

南京大校场历史纪念性景观构建研究

以南京大校场为例,对保护与传承理念下纪念性景观的设计进行探寻,得出了具体的南京大校场设计方案。在设计手法、设计元素、空间布局、材质应用等方面进行了探索,打造一个独特的大校场机场跑道公园,为当代南京大校场的规划建设提供参考。
