Resilience of upland soils to long term environmental changes

摘要: Abstract The effect of long-term changes in land-use, pollution deposition and climate change on upland soils was evaluated by resurveying a large set sites mountain landscape the UK, which were initially sampled forty years ago. Unexpectedly, despite length time between sampling dates, no significant pH, soil exchangeable base cations or C N percentage content weight observed across range type parent material. This suggests that have been relatively resistant to environmental pressures experienced past years, include 1.5 °C increase mean temperature; peak UK sulphur around 1970, followed ~ 90% reduction; increases nitrogen deposition; major grazing intensity. These results suggest may be considerably more resilient future than many previous assessments suggested.
