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.

将生态系统功能添加到基于主体的土地利用模型中。

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固存的兴趣。为了计算这种通量,需要生物地球化学模型。在描述Century模型时,要特别注意它可以包含的土地使用选择。当将Century应用于土地使用问题时,组合选择会导致潜在的难以控制的模拟运行次数。Century也是参数密集型的。提出了将Century输出包含在基于代理的模型中的三种方法,范围从单独计算的查找表到在模拟中运行Century的代理。后者可能是最有效的,但这会将计算成本转移到最容易出现问题的地方。对计算成本的关注不应成为障碍。
