森林景观模型（FLMs）被广泛用于研究干扰对长期和大尺度森林生态系统动态的影响。然而，flm不太适合模拟某些类型的管理或干扰制度，包括土地利用变化。因此，在某些情况下，研究人员可能希望从不同的模型、经验观察或其他来源估计外部事件的时间和位置，然后将它们合并到FLM中。我们提出了Land Use Plus (LU+)，这是LANDIS-II FLM的扩展，允许用户将外部开发的、空间和时间上明确的土地使用或其他干扰表示集成到模拟中。LU+允许用户模拟这些事件对森林组成和生物量的近似影响，以及随后的动态，包括树木的建立和未来管理的潜力。LU+将大大增加研究问题的广度，LANDIS-II可以适当地用于这些研究问题。
Forest landscape models (FLMs) are widely used to examine the influence of disturbances on long-term and broad-scale forest ecosystem dynamics. However, FLMs are not well-suited to simulating some types of management or disturbance regimes, including land-use change. Consequently, there are situations in which a researcher may wish to estimate the timing and location of events externally, either from a different model, empirical observations, or some other source, and then incorporate them into an FLM. We present Land Use Plus (LU+), an extension for the LANDIS-II FLM that allows users to integrate externally-developed, spatially and temporally explicit representations of land use or other disturbance into simulations. LU+ allows users to model the proximate effects of these events on forest composition and biomass, as well as subsequent dynamics, including tree establishment and the potential for future management. LU+ will significantly increase the breadth of research questions for which LANDIS-II may be appropriately used.
