PI: J.F. Reynolds and L. F. Pitelka Institution: Duke University Proposal Number: DEB - 9812440 There exist two generally broad categories of forest-growth models: gap models which deal with long-term population dynamics of vegetation structure and stand models, which deal with short- to medium-term physiological processes such as gas fluxes and plant growth. A fundamental question regarding these models is how much physiology from stand models needs to be incorporated into gap models to effectively simulate long-term vegetation responses to global change. A workshop would be help to evaluate this question. It would assemble a range of investigators with experience on both types of models and employ strategies that combine model comparisons and model assessments. The workshop will ensure that forest growth models are developed that are effective in evaluating projected changes in global climate and in elevated carbon dioxide concentrations. This will improve the utility of forest-growth models in developing important management decisions.

主要研究者： J.F. Reynolds和L. F.机构：杜克大学 建议编号：DEB - 9812440 一般有两大类森林生长模型：处理植被结构长期种群动态的林隙模型和处理气体流通和植物生长等中短期生理过程的林分模型。 关于这些模型的一个基本问题是，有多少生理从林分模型需要纳入到差距模型，以有效地模拟长期植被对全球变化的反应。研讨会将有助于评估这一问题。它将召集一批对这两种模型都有经验的调查人员，并采用将联合收割机模型比较和模型评估相结合的战略。 讲习班将确保开发的森林生长模型能够有效地评估全球气候和二氧化碳浓度升高的预计变化。 这将提高森林生长模型在制定重要管理决策方面的效用。
