Typical Mathematical and Statistical Methods in the Cycle of Carbon and Nitrogen in Forest Soil

The coupled carbon-nitrogen cycle in the terrestrial ecosystem is a complex system between plant and soil, directly impacting the biosphere. The typical mathematical and statistical methods in studying the cycle of carbon and nitrogen in forest soil have been reviewed through dozens of literatures. Statistical methods play an irreplaceable role in processing the collected experimental data, and mathematical methods and models provide strong support for explaining the mechanism of C–N cycle in forest soil. Those presented typical methods can act as important references for researchers in the field of the cycle of carbon and nitrogen in forest soil.
