Description

The emissions of nitrous oxide have dramatically increased due to human activities. In this paper, we assessed the impacts of land use conversions to the nitrous oxide emissions. We collected data from 40 studies and analyzed them based on three conversion groups: forest to degraded forest, forest to crop, and forest to pasture. We generated regression lines and found that the logarithmic model best fits the conversion from forest to degraded forest with R2= 0.396; the Fréchet Distribution best fits the conversion from forest to crop with R2=0.241 and the conversion from forest to pasture with R2 =0.197. The trends of nitrous oxide emissions we manipulated are similar to the study done by Lent, Hergoualc’h, and Verchot. Lent’s Model. In order to more accurately assess the impacts to nitrous oxide emissions in the future, we need to collect and analyze data according to divided regions to eliminate the gaps of data measurements which are caused by differences in temperature, light intensity, and soil types.
