英文摘要: Land use intensification in northern regions has resulted in major land cover transformations that havegenerally negative impacts on traditional land use systems. We examined land cover disturbances inthe Lappi reindeer herding district in North-Eastern Finland between 1965 and 2005 using multi-sourceremote sensing and GIS data. We utilised a series of Landsat MSS and TM data, KH-9 images, aerialphotography and national GIS databases to detect land cover changes and accumulation of disturbancesin a study area of 4504 km2. The results showed that the cover of continuous (old) coniferous forestswas notably reduced by the 1970s, and the undisturbed forest cover further declined from 87 to 77%during the study period. The length of the road network increased from 835 km in 1972 to 1855 kmin 2010. We estimate that circa 27% of the total area in the reindeer herding district has experiencedmajor disturbances since the late 1960s owing to modern forest management, road construction andhydroelectric reservoirs. These long-lasting or permanent land cover changes have had several negativeeffects on reindeer pastures and have increased vulnerability of the reindeer herding system. © 2013 Elsevier B.V.
