Simulation of Direct Effects of CO2 and Temperature Increase on Forest Growth: The Lteef Project

摘要: In the first phase of EU-funded project on “Long-Term Effects CO2 and Climate Change European Forests (LTEEF)”, which ran from 1994–1997, a range models has been used to analyse long-term effects climate change existing forest ecosystems in Europe. This was done by applying at set generic types, combination with scenarios generated accordance recent GCM output. scenario analysis, special attention paid acclimation changing site conditions, impacts growth rates, phenology timing vegetation-atmosphere exchange water carbon dioxide. Results obtained so far show high variation model output, even when applied using same input data for thereby reflecting differences modelling concepts resulting sensitivity conditions. Modelling results agreement increases as result increased temperature, but output requires additional evaluation determine suitability individual such analysis. second (1998–2000) will be updated experimental work carried out within ECOCRAFT project, tested against time series daily values fluxes measured EUROFLUX programme eddy-covariance measurements. Based this evaluation, selected then inventory regional-scale forests, well regional feedback’s terms sequestration over
