Assessment and Application Analysis on Forest Soil Organic Carbon Models
摘要
Abstract
Forestry soil organic carbon (SOC) is an important component of the global carbon cycle > which effects the global carbon balance. Presently, the changes in SOC stock can arise because of the climatic changes or changes in the land use and land management. Here we introduced various kinds of estimating methods on forest SOC, analyzed characters, excellences and disadvantages of each method, enumerated the principal features of the most popular existing soil organic matter (SOM) models dealing with C and N turnover. At least 250 models dealing with soil carbon and nutrient turnover existed. Among these models, we considered in detail the mechanistic compartment-based models. Based on their internal structure, models describing SOM dynamics could be divided into (1) process-oriented and (multi)-compartment models, (2) organism-oriented (food-web) models, (3) cohort models describing decomposition as a continuum, and (4) a combination of model types (1) and (2). The new features, areas supported capabilities, spatial and temporal scale, uncertainty and limitations of main SOC models were introduced. According to the mechanism of CENTURY, principles and methods of some influence factors including the parameters of soil, plant, and climate were advanced. With the CENTURY model uncertainty and influence factor of precision, conceptual basis and scientific detail were analyzed.关键词
