A sediment sequence from a small forest lake in southwestern Sweden was investigated to explore the effects of forestry and land-use on catchment erosion and delivery of organic and minerogenic matter to the lake. Catchment-scale vegetation changes during the last 1,100 years were reconstructed quantitatively at 50-year resolution using pollen analysis and the Landscape reconstruction algorithm (LRA). Variations in terrestrial organic matter input to lake sediments were assessed by total organic carbon (TOC) content and carbon to nitrogen (C/N) ratios. Changes in minerogenic matter were analysed using X-ray fluorescence (XRF) scanning. The results show that Skogaryd was not intensively used for agriculture throughout the past 1,100 years, but its land-use changes were very sensitive to societal changes. Between ca. ad 950 and 1350, local land-use was characterized by small-scale agricultural activities associated with the Medieval expansion, and enhanced soil erosion was recorded by increased K, Ti and Rb deposition. Around ad 1350 much of the farmland was abandoned, most likely in response to outbreaks of plague. The abandonment of farmland caused increased coniferous woodland cover and lower soil erosion. From the 16th century land-use expanded and gradually intensified, concurrent with a population increase documented in the study area between ca. ad 1600 and 1850. Intensive exploitation of the forest led to soil erosion and increased terrestrial organic and minerogenic matter export to the lake. These processes peaked with the artificial drainage of a nearby wetland for agricultural purposes. During the 20th century, modern forestry management started with the plantation of conifers, and soil erosion declined.

研究了瑞典西南部一个小型森林湖中的沉积物序列，以探讨林业和土地利用对流域侵蚀以及向湖中输送有机和成矿物质的影响。使用花粉分析和景观重建算法（LRA），以50年的分辨率定量重建了过去1100年的流域尺度植被变化。通过总有机碳（TOC）含量和碳氮比（C / N）来评估输入湖沉积物中的陆地有机物的变化。使用X射线荧光（XRF）扫描分析了成矿物质的变化。结果表明，在过去的1100年中，斯科加里德（Skogaryd）并未广泛用于农业，但其土地利用变化对社会变化非常敏感。之间。广告950和1350年，当地土地利用的特征是与中世纪扩张相关的小型农业活动，而土壤侵蚀的增加是由于钾，钛和deposition的沉积增加所致。围绕广告1350多的农田被废弃，最有可能在应对鼠疫的爆发。放弃耕地导致针叶林地覆盖面积增加，土壤侵蚀减少。从16世纪开始，土地利用范围不断扩大和加剧，同时研究地区之间的人口增加也记录在案。广告1600年和1850年。森林的集约化开发导致水土流失，并增加了向湖泊出口的陆地有机和成矿物质。这些过程在附近的农业湿地人工排水中达到了顶峰。在20世纪，现代林业管理始于针叶树的种植，水土流失有所减少。
