Abstract:

To study the spatial changes of forest soil carbon components across urban-rural forest transects in Beijing, we set up four urban-rural transects in Beijing (northeast, northwest, southwest and due south) from the city center (The Imperial Palace) to the rural, and randomly selected 20 independent urban forest parks for sampling. We randomly selected three typical forest patches in each park from late June to early July 2019, collected soil samples from the surface layer (0-10 cm) and subsurface layer (10-20 cm), and measured the content of soil total carbon, organic carbon, particulate organic carbon and mineral associated organic carbon. The dataset includes: (1) geolocation of the sample sites; (2) content of topsoil total carbon, organic carbon, inorganic carbon, particulate organic carbon and mineral associated organic carbon across urban-rural forest transects in Beijing region; (3) topsoil carbon fractions and different drivers, including: soil data (soil pH and soil claysilt), vegetation data (vegetation coverage, park age, common tree species number), climate data (mean annual temperature and precipitation). The dataset is archived in .shp and .xlsx data formats, and consists of 8 data files with data size of 30.7 KB (Compressed into one single file with 27 KB). The analysis paper based on the dataset was published at Acta Geographica Sinica, Vol. 79, No. 1, 2024.
