In the Pinus taiwanensis forest in Daiyun Mountain National Nature Reserve in Fujian Province, a total of twelve 10 m×10 m simulated nitrogen deposition plots were set up, which all of facing the same direction with similar slope and altitude. The experimental treatments included control (CT, 0 kg N hm-2a-1), low nitrogen (LN, 40 kg N hm-2a-1), and high nitrogen (HN, 80 kg N hm-2a-1), with 4 replicates for each treatment. The experiment started in May 2018, and after two years of simulated nitrogen deposition, a dataset of soil organic nitrogen depolymerizing enzyme activity in response to nitrogen addition was obtained. This dataset included: (1) location of sample sites; (2) the impact of nitrogen addition on soil biochemical properties; (3) the impact of nitrogen addition on soil organic nitrogen depolymerizing enzyme activity. The dataset was archived in the .shp and .xlsx formats, consisting of 8 data files with data size of 21.3 KB (compressed into 1 file with 17.4 KB). The analysis paper based on the dataset was published in Acta Ecologica Sinica, Vol. 43, No. 16, 2023.
