摘要: The title of the thesis is "Impact cropping systems and climate change on soil carbon sink in a Mediterranean area". research was carried out in North East Sardinia area, near the Berchidda Monti towns. This area characterized by several system such pasture, short term forage crops vineyard. aim to evaluate influence of different dynamic organic matter how climatic could modify crop production sink. study using EPIC simulation model. A pedologic, vegetational characterization studied were out. Through this we obtained information useful describe site cropping systems. Moreover data, characterization, used as input data for the EPIC simulation model. After calibration EPIC model several simulations pasture short crops cropping systems. In order effects and soil sink, have 2 different scenarios (based A2 B2 green house gas emission proposed IPCC) generated general circulation (HadCM3 and GISS) create "future weather" file
