摘要 基于森林生长过程的模型是辅助森林管理的有力工具,其包含描述森林生理、生态和物理过程的组件,基于这一过程的3-PG模型用于研究林木生长过程中考虑树种的生理特性,并结合立地条件、气候条件以及经营管理等措施,预测在各种变化条件下的森林生长情况。文中通过对3-PG模型参数及参数敏感性的分析来表述3-PG模型研究现状,概述了3-PG模型在林业中的应用研究进展,认为其将很好地解决大区域尺度下的森林动态生长变化问题,并对该模型的发展进行了展望。 The models of forest growth process are important tools for assisting forest management, which contain components that describe forest physiological, ecological and physical processes. The3-PG model was used to study the physiological characteristics of tree species in the process of forest growth, and combine with site conditions, climatic conditions, management and other measures to predict the forest growth under various changing conditions. This paper described the research status of3-PG model by the analysis of parameters and parameter sensitivity, summarized the research progress of3-PG model in forestry application, pointed out that the3 -PG model could solve the problem of dynamic growth of forest in large regional scale, and prospected the development of this model.
