Abstract

Abstract:

Background and Aims Most studies of the consequences of enhanced nitrogen deposition on sources and sinks of greenhouse gases have been performed in temperate ecosystems. Little information is available about greenhouse gases and responses to atmospheric nitrogen deposition in subtropical and tropical forests, especially in the forests of China. The objective of this study was to determine soil N₂O emission and its response to simulated N deposition in pine forest (PF), pine-broadleaf mixed forest (MF), and monsoon evergreen broadleaf forest (MEBF) of Dinghushan in subtropical China.

Methods Four N addition treatments (in three replicates) were established in MEBF: Control, Low N (50 kg N·hm^-2·a^-1), Medium N (100 kg N·hm^-2·a^-1) and High N (150 kg N·hm^-2·a^-1), and three treatments were established in MF and PF (Control, Low N and Medium N).

Key Results The effects of nitrogen addition on soil N₂O emission differed by forest type. In MF, no significant differences were found among the three treatments after 3 months. In PF, however, soil N₂O emission rate was significantly higher in Medium plots than that in Low or Control plots, which exhibited no significant difference. In MEBF, soil N₂O emission rate was highest in High N plots and significantly higher in Medium plots than in Low or Control plots, which exhibited no significant difference.

Conclusions This study suggests that nitrogen addition significantly stimulated soil N₂O emission rates in both MEBF and PF, and its effect generally increased with the levels of nitrogen addition, but there was no such significant effect in MF.

Key words: N deposition, N₂O emission response, Subtropical forest, China
