异速生长关系在陆地生态系统生物量估测中的应用

The Application of Allometric Relationships in Biomass Estimation in Terrestrial Ecosystems

随着全球变化问题的日益加剧,迫切需要了解陆地生态系统碳储量和碳循环的有关情况,而其中的核心问题之一就是生物量的准确估测。异速生长关系在间接估测陆地生态系统生物量的过程中扮演着重要角色。本文首先概述了近年来异速生长关系在陆地生态系统生物量估测方面的应用情况,并对其常见形式做了介绍。然后简述了与生物量估测方程拟合相关的一些统计学问题,还对立地间、物种间异速生长关系整合等前沿问题做了概述。最后展望了未来的研究与应用的发展趋势。

Global climate change has inspired an increasing interest in global carbon storage and carbon balance, and therefore, ecologists pay more attention to the estimate of global terrestrial biomass. Allometric relationships play the most important role in terrestrial biomass estimation. We introduced the progress in the application of allometric relationships in biomass estimation in recent decade ,and then discussed some statistical issues in model fitting process. Some frontier problems such as site-general and species-general biomass estimation equations were also addressed. Finally,some researches and applications were emphasized in future.
