摘要/Abstract

摘要： 森林景观模型能够基于传统的野外调查数据和数学模型定量模拟景观尺度森林结构和功能的时空变化,可为制定科学的森林经营管理策略提供参考。FireBGCv2是当前研究森林景观变化的代表性模型之一,能模拟树木尺度(树木生长、建立和死亡等)、林分尺度(碳氮库、可燃物处理、分解等)、立地尺度(资源竞争和物种物候等)以及景观尺度(种子传播和林火干扰等)等多个尺度上的生态过程及其对森林景观结构和功能的影响。该模型的优点是能模拟多种生态过程,且考虑了生态系统的多样性和复杂性,但亦存在计算量大、使用较复杂等缺陷。本文归纳总结FireBGCv2的基本原理和结构,并介绍其在森林景观研究和管理中的应用进展。目前,国内外对FireBGCv2模型的应用主要集中在探索火灾、气候和植被的相互作用,量化火灾的空间和时间动态以及描述未来气候和土地管理策略下潜在的火灾动态等。随着森林景观模型理论和应用的深入发展,FireBGCv2的发展前景主要是改进和更新模型的算法、增加新的功能模块以探索火灾管理的问题以及满足不同用户的需求等。

Abstract: Forest landscape model can quantitatively simulate the spatiotemporal variations in forest structure and function at the landscape scale based on traditional field survey data and mathematical models, providing a reference for the formulation of scientific forest management strategies. FireBGCv2 is one of the representative models currently used in the research area of forest landscape changes. It can simulate ecological processes at various scales, including trees scale (tree growth, establishment, and mortality), stand scale (carbon and nitrogen pools, fuel treatment, decomposition), site scale (resource competition and species phenology), and landscape scale (seed dispersal and wildfire disturbances), and the effects of those processes on forest landscape structure and function. The advantage of this model lies in its ability to simulate multiple ecological processes while considering the diversity and complexity of ecosystems. However, it also has drawbacks, such as high computational demands and complexity of use. We summarized the basic principles and structure of FireBGCv2 and introduced its application progress in forest landscape research and management. Currently, the application of the FireBGCv2 model, both domestically and internationally, mainly focused on exploring the interactions between fire, climate, and vegetation, quantifying the spatial and temporal dynamics of fires, and describing potential fire dynamics under future climate scenarios and land management strategies. With the in-depth development of forest landscape model theories and applications, the future prospects of FireBGCv2 include improving and updating the model's algorithms, adding new functional modules to explore fire management issues, and meeting the needs of different users.
