Out of the Peat: Preliminary Geophysical Prospection and Evaluation of the Mid-Holocene Stationary Wooden Fishing Structures in Haapajärvi,Finland

The huge scientific and interpretive value of wetland archaeological sites has been well demonstrated in several studies. The management of the archaeological resource of wetland landscapes is problematic, however, and there is an urgent need for noninvasive techniques to detect waterlogged organic archaeological remains. Stationary wooden fishing structures associated with fishing sites constitute an important wetland archaeological resource in northern Europe. In Finland, similar wooden constructions have been used for fishing from prehistory to the early modern era. The discovery of sites has been accidental, because the waterlogged organic remains have been considered invisible to conventional geoprospection techniques. Because of this, a small project was launched at Lamminoja, northwest Finland, in order to investigate whether it would be possible to improve our chances to detect fishery sites in demanding wetland habitats. New information was obtained through geophysical prospection, trial excavations, and accelerator mass spectrometry (AMS) dating. Geophysical testing was hampered by several factors, including complex sediments affected by modern drainage. New information was obtained, however, on the composition, age, and spatial distribution of the wooden fishing structures preserved in peat over 5000 years.     

内蒙古中南部考古学文化演变的环境学透视

内蒙古中南部位于我国北方农牧交错带的中段, 是气侯变化的敏感地区。全新世以来的气侯波动, 对于塑造这里的自然景观和古文化的面貌起着重要的作用。本文分析了全新世大暖期的不同时段上古文化的特点和生计方式的变化, 并从沙地进退、湖面升降的视角探讨了这一地区考古学文化的演变以及人地之间相互作用的过程。     

五代时期的扬州城考

英藏敦煌文献S.529(V)号《诸山圣迹志》(又名《失名行记》)记载了五代时期的扬州城周里数,为研究五代时期的扬州城提供了极其珍贵的第一手资料。本文以敦煌文献S.529(V)号的记载为依据,利用古籍记载和考古资料,论证了五代时期扬州城存在的事实,同时利用该文献对扬州城的规模和城门数进行了探讨。     

谈谈考古遗址的展示保护

本文讨论了考古遗址的风化状况和原因,指出考古遗址的破坏是多种因素共同作用而产生的,为了保护考古遗址,就要采用多种相应的技术措施。这些措施包括:保护房的建设、地下水的治理、土体的机械和化学加固及生物因素的控制等。在遗址保护中要根据实际情况选择保护手段。
