进行大规模实地实验的机会很少，但提供了一个独特的机会来揭示在自然生态系统中运作的复杂过程。在此，我们回顾了现有的大规模森林破碎化实验的设计。在此综述的基础上，我们为改变森林生态系统的稳定性（SAFE）项目设计了一个新的森林破碎化实验，该项目将在马来西亚婆罗洲（沙巴州）的低地热带森林进行。SAFE项目在现有实验的基础上取得了进步，因为它：(i)允许将景观级森林覆盖的影响与斑块级过程区分开来；（ii）旨在促进在广泛的空间尺度上运作的关于生态格局和过程的各种数据类型的统一；（三）比现有实验具有更大的重复性；（iv）包括对河岸走廊的实验性操作；(5)将实验破碎的景观嵌入比现有项目更广泛的土地利用强度梯度中。SAFE项目为跨学科的生态学家提供了一个机会，使他们能够参与一项旨在广泛了解热带森林改造对生态影响的大型倡议。
Opportunities to conduct large-scale field experiments are rare, but provide a unique opportunity to reveal the complex processes that operate within natural ecosystems. Here, we review the design of existing, large-scale forest fragmentation experiments. Based on this review, we develop a design for the Stability of Altered Forest Ecosystems (SAFE) Project, a new forest fragmentation experiment to be located in the lowland tropical forests of Borneo (Sabah, Malaysia). The SAFE Project represents an advance on existing experiments in that it: (i) allows discrimination of the effects of landscape-level forest cover from patch-level processes; (ii) is designed to facilitate the unification of a wide range of data types on ecological patterns and processes that operate over a wide range of spatial scales; (iii) has greater replication than existing experiments; (iv) incorporates an experimental manipulation of riparian corridors; and (v) embeds the experimentally fragmented landscape within a wider gradient of land-use intensity than do existing projects. The SAFE Project represents an opportunity for ecologists across disciplines to participate in a large initiative designed to generate a broad understanding of the ecological impacts of tropical forest modification.
