美国东部杜克森林长期定位研究综述

LONG-TERM STUDIES OF FOREST DYNAMIC IN THE DUKE FOREST,SOUTH EASTERN UNITED STATES:A SYNTHESIS(REVIEW)

该文比较系统地综述了美国东部杜克森林76年来植物种类变化、种群动态和森林演替研究的基本情况。重点介绍了该森林内永久性森林样地的设置和调查规范,以及最近10年来利用永久样地数据进行树木空间格局和自然干扰研究的最新进展,并将杜克森林永久样地监测规范和数据管理方法与目前主要的森林监测网络进行了一定的比较,旨在对目前国际上蓬勃开展的长期定位植物多样性监测和空间格局研究有所启示和帮助。

A growing need for long-term condition and trend information across natural and anthropogenic landscapes is promoting interest in long-term permanent plot research. In this review, we introduced the 76- year history of management and research on forest dynamics in the Duke Forest, NC. This forest has been intensively studied since the early 1930s and has become a model system for ecological and environmental education and research in the eastern United States. We summarize and assess research in the Duke Forest on forest environment, the current network of long-term permanent vegetation plots, survey protocols, data management procedures, and major research findings from those long-term plot data. We also summarize more broadly the current status of long-term research on the natural dynamics of Piedmont forests of the southeastern United States. Lessons leamed from the Duke Forest research site could inform the design of a world-wide, long-term network of research plots for monitoring and assessment of forest dynamics and trends in species composition and biodiversity.
