doi:10.7523/j.issn.2095-6134.2001.1.014

Abstract

Abstract:

Based on observed soil carbon density data over wold wide and model results of net primary production, a simple model was built that can be used directly in calculating average soil respiration rate and soil carbon density. The simulated results have been compared with measurements. According to our model results, the recently view that averaged soil respiration rate does not vary with temperature is under debatable. Using this model, we simulate the distribution of potential soil carbon density on global scale,the calculated global soil organic carbon pool is 1152 Pg. This simple model can successfully simulate the large differences of soil carbon density at different precipitation (or soil moisture) situations.

Key words: average soil respiration rate, soil caron density, carbon pool, climate data, model
