摘要:
ABSTRACTShore displacement at Stockholm has been studied by indications of former water levels from e.g. tide-pole records, old oak-trees,14C-datings of sediments in lakes isolated from the Baltic and archaeological material. Through the excavations at Helgeandsholmen, more material has appeared to give information about the process on the Baltic (“Saltsjö”-) side of the town. It has been found that shore-displacement at Stockholm is not so regular as was previously thought. Eustatic factors strongly modify the isostatic uplift that might be considered more or less linear over the last millenium. Since the isolation of Lake Mälar that probably occurred in the 12th-13th centuries the lake has cut down its outlet (mainly at Norrström) at about the same rate that shore displacement has taken place on the Baltic side. However, this process has stopped during the last 3–4 decades, due to regulation of the water level through damming.
