Abstract: The closed chamber method was used to observe the characteristics of N₂O emission from rice fields in the hilly area of southern Jiangsu province. The results showed that the N₂O emission fluxes varied between 22-31μg N₂O-N·m^-2 ·h^-1 during rice-growing season. The N₂O emission was enhanced by application of urea. 0.038%-0.195% of urea nitrogen added was lost to the atmosphere as nitrous oxide. There was no obvious correlation between fertilizer application rates and mean N₂O fluxes. Under the condition of water management of drying and irrigation alternation, the precipitation significantly influenced N₂O fluxes.

Key words: settlement morphology, commuting, urban transportation, energy consumption, greenhouse gases emission.
