Abstract: Based on the theory of functional ecology, a new method for distinguishing soil types according to its characteristic mass(CM)and characteristic time(CT)was presented. By mathematical modeling, the CM and CT of Soddy-podzodsand Cherro zem was calculated as the orders of 133 t穐m-2 and 80 years with an annual litter-fall mass about 5.5 t穐m-2 for Soddy podzods, and 820 t穐m-2, 650 years with an annual litter-fall mass 11.2 t穐m-2 for the Cherro zem. Further more, the CM and CT varied with the change of mass input and decomposed velocity in the soil, which are influenced by the external factors(light, temperature, moisture etc.)and anthropologic factors. We also found that the lower the horizon was, the longer the CT would be.
