本文的目的是研究在基于主体的土地利用决策模型中纳入生态系统功能模拟的问题。纳入这些模拟的原因包括当地对土地肥力的兴趣和全球对碳封存的兴趣。为了计算这种通量，需要建立生物地球化学模型。在描述世纪模型时，特别注意了它可以包含的土地使用选择。当世纪被应用于土地利用问题时，组合选择导致潜在的不可管理的模拟运行次数。世纪也是参数密集型的。给出了在基于代理的模型中包含世纪输出的三种方法，从单独计算的查找表到在模拟中运行世纪的代理。后者可能是最高效的，但它会将计算成本转移到问题最严重的地方。对计算成本的担忧不应成为障碍。
The objective of this paper is to examine issues in the inclusion of simulations of ecosystem functions in agent-based models of land use decision-making. The reasons for incorporating these simulations include local interests in land fertility and global interests in carbon sequestration. Biogeochemical models are needed in order to calculate such fluxes. The Century model is described with particular attention to the land use choices that it can encompass. When Century is applied to a land use problem the combinatorial choices lead to a potentially unmanageable number of simulation runs. Century is also parameter-intensive. Three ways of including Century output in agent-based models, ranging from separately calculated look-up tables to agents running Century within the simulation, are presented. The latter may be most efficient, but it moves the computing costs to where they are most problematic. Concern for computing costs should not be a roadblock.
