CENTURY: MODELING ECOSYSTEM RESPONSES TO CLIMATE CHANGE, VERSION 4 (VEMAP 1995)

The CENTURY model, Version 4, is a general model of plant-soil nutrient cycling that is being used to simulate carbon and nutrient dynamics for different types of ecosystems including grasslands, agricultural lands, forests and savannas. CENTURY is composed of a soil organic matter/ decomposition submodel, a water budget model, a grassland/crop submodel, a forest production submodel, and management and events scheduling functions. It computes the flow of carbon, nitrogen, phosphorus, and sulfur through the model's compartments.

CENTURY模型（CENTURY Model）第4版是一款通用的植物-土壤养分循环模型，目前被应用于模拟草原、农田、森林及稀树草原等各类生态系统的碳与养分动态。该模型由土壤有机质分解子模型、水量平衡模型、草原/作物子模型、森林生产力子模型，以及管理与事件调度功能模块构成，可计算碳、氮、磷、硫在模型各组分隔室中的流动过程。
