Dataset of effects of warming and nitrogen addition on soil phosphorus bioavailability in China's mountainous areas

This data was screened from papers published between 2000 and 2024 in China National Knowledge Infrastructure (CNKI) and Web of Science databases (keywords: warming, nitrogen addition/position, soil bioavailable phosphorus, soil phosphorus fractions), and two screening criteria were established: (1) the study must be conducted in situ simulated warming or nitrogen addition experiments in the field; (2) The research data information must be complete, including the average values and sample sizes of the selected variables in the control and treatment groups. After screening, it was found that there were only 4 foreign in-situ warming experimental studies that met the requirements. In order to avoid spatial non-uniformity of data, this study focuses on the results of relevant research in China, including 30 literature on warming, with a total of 98 data points; There are 82 literature on nitrogen addition, with a total of 422 data points. Extracting data includes: (1) latitude and longitude, climate factors, and altitude of the sample points; (2) Biological available phosphorus data, replicates, and standard deviation between the experimental group and the control group; (3) Variables such as soil physicochemical properties and ecosystem types; (4) Heating amplitude and nitrogen addition amount (type), heating temperature and nitrogen addition time and method.
