In the Maujahn peat bog the Slavic period is recorded with a high-resolution pollen diagram in 150 cm of the peat profile. In the upper part of the pollen diagram the time resolution is 3.2 years in the middle and lower part 5.2 years. The Slavic period can be divided into four stages according to different kind of land use and intensity of human influence. The main crop was Secale; less important was the cultivation of Triticum, Panicum, Hordeum, Avena and Pisum. The Slavic period lasted from about a.d. 800–1200. The pollen diagram also displays a final part of the Migration period.  相似文献

Pollen analysis was carried out on gyttja from the small lake Femtingagölen in the Småland Uplands, southern Sweden. The interpretation of the pollen diagram focused on land-use history and comparisons were made to archaeological and historical information from the area. An absolute chronology, based on AMS dates from terrestrial plant macrofossils, was complemented by inferred dates. The pollen analytical data suggest interference with the woodland cover from ca. 1700 B.C. onwards. Intensified grazing and forest clearances resulted in semi-open pastures between ca. A.D. 400–600 which was followed by forest regeneration (chronology based on AMS 14C dates and cross-correlation with other well dated profiles). The landscape became more open again between A.D. 800 and 1400. Animal husbandry was complemented by small-scale shifting cultivation during the Iron Age. Permanent arable fields were probably not introduced until the Late Iron Age or the Middle Ages. Hordeum and Triticum were grown during the Iron Age, Hordeum, Triticum, Secale and Cannabis sativa during the Middle Ages and early Modern time, and Hordeum and Avena in the recent past. Sandy and silty soils, where stone clearance was not necessary, have probably been used for cereal growing in prehistoric and historic time.  相似文献

Pollen profiles, based cores taken in Lake Kahala and from the adjoining mire, were used to establish general vegetation history and to reconstruct the extent and types of land-use over most of the Holocene. Modern pollen deposition was studied using moss polsters and the results were used in the interpretation of the fossil pollen data in terms of former land-use practices. The modern-day samples are from settlements, hay meadow and pasture, and overgrown pasture. Indications of human activity can be traced back to the Stone Age. At ca. 6400 cal. B.C., the first indications of possible woodland utilisation by humans are recorded. This may have involved grazing within the forests. From 4200 cal. B.C. onwards, animal husbandry with changing intensity was practised. Arable farming, involving cereals, was introduced to the area at ca. 1800 cal. B.C., but it was only at ca. 500 cal. B.C. that it assumed an important role in the farming economy.Secale cereale (rye) was introduced during the Roman Iron Age, intensive rye cultivation started at the end of the Iron Age, at ca. cal. A.D. 800. Ever increasing farming pressures triggered the formation of openalvars. Open landscape similar to that of today has persisted, with minor forest regeneration phases, since at least 500 cal. B.C.  相似文献

In 1985 archaeological excavations at Stavanger Airport, Sola, south-western Norway, revealed evidence for five phases of human activity ranging in age from the Mesolithic to the Late Bronze Age. The two youngest phases, namely 4 and 5 which reflect agrarian activity, are considered in detail in this paper. The fourth phase, which dates to ca. 3500 B.P., contains the first evidence of animal husbandry at the site and, in the fifth phase, there is evidence for a mixed farming economy. Physical evidence of cultivation includes intersecting patterns of plough-marks and, at seven sites, pollen assemblages indicative of arable farming have been recorded. The arable fields, in which weed-rich crops of Hordeum and Triticum were grown, date to ca. 2550-2200 B.P. The fields were subsequently covered by a thick layer of aeolian sand.  相似文献

Long term (from the Mesolithic to the Bronze Age) habitation of the Akali settlement on a clearly defined bog-island in East Estonia is used as an example of transitional development from a prosperous foragers’ habitation centre to a hinterland of established farming cultures, taking place through availability, substitution and consolidation phases of crop farming in the boreal forest zone. The pre-Neolithic finds of Triticum and Cannabis t. pollen at c. 5600 b.c. are interpreted as possible indications of the acquaintance of foragers with farming products, through contacts with central European agrarian tribes during the availability phase. The substitution phase is marked by more or less scattered pollen finds of various cereals and hemp and, at Akali, is connected with Neolithic period 4900–1800 b.c. An increasing importance of crop farming in the economy is characteristic of the consolidation phase, but because natural conditions are unfavourable for arable land-use, a regression of human presence is recorded during the second part of the Neolithic. The settlement was abandoned during the Bronze Age at the time when crop farming become the basis of the economy in Estonia. The re-colonisation of the area, traced to ca. a.d. 1200, took place for political reasons rather than through increasing suitability of the landscape.Editorial responsibility: Felix Bittmann  相似文献

Soil samples from a late Neolithic stone cist in Hamneda, southern Sweden, were pollen analysed. The results of the analysis suggest that the local vegetation at the time of the burial was a half-open woodland with pasture and small-scale cereal growing, intermingled with stands ofTilia (lime),Quercus (oak) andCorylus (hazel). The analysis also gives unique information on the burial ritual. High pollen percentages ofHordeum type,Triticum type and undifferentiated Cerealia from among the shards of a pot deposited in the cist show that the pot originally contained cereal grains, bread, porridge, gruel or beer. Furthermore, the analysis shows that flowers ofAnemone nemorosa were deposited on or beneath the dead body in the cist.  相似文献

Palaeoecological investigations of mires suggest that agriculture was established north of the Arctic Circle in Norway during the late Bronze Age (1100?C500 b.c.) and Pre-Roman Iron Age (500?C1 b.c.). The lack of archaeobotanical and archaeological investigations has made it difficult to assess the nature of this early agricultural expansion into the Arctic in any detail. Here we present the first well documented archaeobotanical investigation from north Norway that covers this agricultural pioneer phase. Remains of charred seeds show that barley (Hordeum) was already being cultivated in the late Bronze Age, and that wheat (Triticum) was introduced in the Pre-Roman Iron Age. Large amounts of crowberry (Empetrum) seeds are also typical of the Pre-Roman Iron Age and were obviously an important food plant at the time, at least locally. Charcoal rich layers dated to the late Bronze Age suggest that the local birch forest was initially cleared away with the help of fire, possibly related to a slash-and-burn cultivation practice. Lithostratigraphic and pollen-analytical results indicate that the cultivation practice of the Pre-Roman Iron Age was a form of bush-fallow system with intensive soil re-working alternated with long periods of fallow.  相似文献

The sediment stratigraphy of a medium-sized mixotrophic lake (Ruila) situated below the highest shoreline of the Baltic Ice Lake in the West-Estonian Lowland is described. The lake is without natural inlets our outlets. The reconstruction of vegetation and land-use history based on pollen data, combined with available archaeological data and detailed 14C dating allows us to give a provisional reconstruction of the temporal and spatial pattern of natural and human induced environmental changes in north-west Estonia during the Holocene. Both radiocarbon dates derived from terrestrial macrofossil dating by accelerator mass spectrometry (AMS) and conventional dating of bulk lake sediment are discussed. The isolation of the lake basin from the Yoldia Sea took place ca. 9700 cal B. C. The Ancylus Lake transgression at ca. 8400 cal B. C. did not reach the basin, but caused a ground water rise, seen in the sediment stratigraphy of the lake. The first signs of human impact on the pollen record appear ca. 5400 cal B. C. (Late Mesolithic). The history of arable farming has been divided into three periods: 1) introduction of crop cultivation and animal husbandry (1500 cal B. C. – A. D. 500); 2) establishment of animal husbandry A. D. 500–1000) and 3) establishment of crop cultivation and intensive cattle breeding (A. D. 1000–today). Due to unfavourable eda-phic conditions the introduction of arable farming was delayed for more than 1000 years compared with elsewhere on the north coast of Esotnia, and intensity of land-use never reached the same proportion as in these areas.

The High Weald is an unusually well-wooded area in southern England. A high proportion of this woodland is ancient, being formerly exploited as seasonal pasture and coppice. Multiple pollen profiles from the Rye area have been used to elucidate the origins of this cultural landscape. By combining sites with small and large pollen source areas, both local and regional patterns of vegetation change have been determined. The mid-Holocene Tilia-dominated woodlands were subjected to temporary clearance as early as the Neolithic. This woodland was more extensively exploited over a ca. 700 year period from the beginning of the Bronze Age. The main elements of the modern landscape (woodland, pasture and limited cultivation) can be traced back to a more intensive phase of human activity, which commenced in the late Bronze Age. A regional increase in Fagus sylvatica pollen ca. 750 B.C. probably reflects the use of the Wealden woods for pasturage. There is no palynological evidence that the fuel demands of the Roman iron industry resulted in widespread woodland destruction. The early Anglo-Saxon period appears to have been one of land-use continuity, with a second increase in Fagus pollen at ca. A.D. 700 corresponding to historical evidence for the presence of wood-pastures in the Weald.  相似文献

An excavation in the near surroundings of the town of Gouda revealed the remains of a wooden farmhouse. Radiocarbon dates and pottery indicate that the farm was built around A.D. 1120–1135. It belongs to the initial phase of land reclamation in the wetlands of the part of the Netherlands called Holland. Pollen and wood analysis show that the original vegetation consisted of ash and alder woodland on a subsoil of eutrophic peat. People used local wood very economically for the construction of the house. A triangular figure of splitPinus sp. andAbies alba branches near the entrance provides an exotic and probably ritual element. The farmers practised mixed farming based on the raising of cattle, pigs and crops comprisingTriticum dicoccum (emmer wheat),Hordeum sp. (barley).Avena sativa (oats),Linum usitatissimum (flax) andCannabis sativa (hemp). Conspicuously absent isSecale cereale (rye). There are no indications of an orchard.  相似文献
