Trade‐off between Structural Diversity and Economic Objectives in Forest Management
提出一种新的多样性测度NAD，可纳入经济优化模型，并应用于多物种森林管理，探讨生态与经济目标间的权衡。
Abstract A measure of divergence (NAD) between the distribution of individuals in a community and a target distribution is presented. When the latter is uniform, NAD measures evenness and exhibits a strong correlation with the widely used Shannon index. However, NAD offers the capability to incorporate an arbitrary composition in an economic optimization model where the Shannon index is not applicable. An empirical application to optimum management of a multispecies forest is presented, and the trade‐off between ecological and economic objectives is investigated.
