Abstract:: This study was conducted in in a subtropical evergreen broad-leaved forest in Wuyishan Mountain and aimed at measuring soil nutrients and soil enzyme activities and the effects of nitrogen deposition. Nitrogen addition experiments were carried out within the forest selected in 2016. Four N addition treatments with three replicates were established in mature forest: control, no N [N₀, 0 kg/(hm²·a)], low N [N₁, 50 kg/(hm²·a)], medium N [N₂, 100 kg/(hm²·a)] and high N [N₃, 150 kg/(hm²·a)]. The results showed that: (1) the soil temperature and soil moisture content had the consistent change trend with the highest in January and the lowest in August; (2) there was a significant effect of nitrogen deposition on soil nutrients, and then increased soil nutrients, while there was no significant effect of nitrogen deposition on soil total phosphorus (p>0.05); (3) soil microbial biomass carbon and nitrogen increased first and then decreased with the increase of nitrogen concentration, while there was no significant effect of nitrogen deposition on soil microbial biomass phosphorus (p>0.05); (4) soil Bglu, Bxyl, NAG, Phos, Phox, Pero enzyme activity increased first and then decreased with the increase of nitrogen concentration, and then increased soil enzyme activities, while there was no significant effect of nitrogen deposition on soil Phox enzyme activity (p>0.05); (5) correlation analysis showed that correlation coefficient between soil water content and soil nutrients and soil enzyme activity in 0—5 cm layer was higher than correlation coefficient in 5—10 cm layer; similarly, correlation coefficient between soil temperature and soil nutrients and soil enzyme activity in 0—5 cm layer was higher than correlation coefficient in 5—10 cm layer, suggesting that soil nutrients and soil enzyme are more dependent on soil temperature.
