2020年南岭山地典型森林生态系统土壤养分数据集

In 2020, this data set will carry out standardized field survey and test effort of soil sample collection for ancient woodland in five typical forest ecosystems, namely, valley tropical and subtropical moist broadleaf forests (<800 m), mountain tropical and subtropical moist broadleaf forests (800 – 1200 m), evergreen coniferous and broad-leaved mixed forest (1200 – 1500 m), mountaintop grassland (>1500 m), and mountaintop evergreen broad-leaved dwarf forest (>1500 m) in the Nanling Mountain forest ecosystem, The soil nutrient data set of typical forest ecosystem in the Nanling Mountain was constructed. This data set includes soil nutrients (organic matter, total nitrogen, total phosphorus, and total potassium) and soil available nutrients (nitrate nitrogen, ammonium nitrogen, available phosphorus, and available potassium) of 0-20 cm topsoil in four quarters, with a view to providing valuable measured data for the study of soil nutrient cycling process in the Nanling Mountain of China.
