摘要
随着人们对森林多功能性认识加深及对森林多种产品与服务的需求增加,森林经营受到更广泛的关注。传统设置样地比较经营活动效果的方式在时间上具有迟滞性,学者认为应采用数学模型对森林经营进行计算机仿真,森林生长与动力学模型在森林可持续经营中应用的作用愈加突出。文中对基于林分经营尺度的森林生态系统混合斑块模型(PICUS)进行引介,详细介绍了其2个基础组成模型——林窗模型与基于生理过程的3-PG模型,对PICUS模型的林木死亡率、更新、森林经营以及森林生态系统地下过程等子模块进行了简要概述,并阐述了该模型在欧洲及中国的应用与启示,对于促进PICUS模型在实践中的推广应用以及提高人们对森林生长过程与动态的认识和理解具有重要意义。
As people have gained the awareness of forest multi-functionality and set more demand for forest ecosystem goods and services,forest management has drawn a wide attention.However,the conventional way of setting sample plots takes time to reflect the effects of forest management.People begin to apply mathematic models to simulate the forest management.Models of forest growth and dynamics play an increasingly prominent role in the development of sustainable forest management.This paper introduces the PICUS model(Forest Ecosystem Hybrid Patch Model),especially the two fundamental models,i.e.,forest gap model and 3-PG model,elaborates the sub-/modules of mortality,regeneration,management and underground process of forest ecosystem,and discusses the PICUS model application in the Europe and China and its inspiration.This study is of great significance to promote the application of PICUS model in practices and increase the understanding of forest growth and dynamics.
