以前广泛的大片的原始雨林已经退化的人类活动，我们研究了如何影响森林干扰所产生的栖息地破碎化和商业选择性采伐影响生态系统功能在这些栖息地的研究落叶分解率的垃圾袋放在森林地面上。婆罗洲的热带雨林主要由龙脑香科的树木组成，我们比较了8个森林碎片地点（面积3-3529公顷）的3种龙脑香物种的落叶分解率，这些森林碎片地点具有不同的干扰预碎片化历史：4个碎片在碎片化之前被选择性地记录，4个碎片是从以前未受干扰的森林中形成的。我们将这些已采伐和未采伐的森林片段与连续森林中已选择性采伐（两个地点）和完全保护且未受干扰（两个地点）的地点进行了比较。120 d后，未受干扰的连续森林网站的分解速度最快（52%的质量损失）。森林碎片形成的未采伐的森林（32%的质量损失）有更快的分解速率比记录的森林碎片（28%的质量损失），但比连续记录的森林（39%的质量损失）的速度慢。光需求的物种（Parashorea malaanonan）的叶子比耐荫物种（Hopea nervosa）的叶子分解得更快，但我们研究的所有三种龙脑香物种的分解对伐木和破碎效应的反应相似。在被砍伐和破碎的森林地点，分解率降低可能影响养分循环，从而对森林再生产生不利影响。应优先进行养护管理，以提高森林质量，特别是在被砍伐的森林片断。
Previously extensive tracts of primary rain forest have been degraded by human activities, and we examined how the effects of forest disturbance arising from habitat fragmentation and commercial selective logging affected ecosystem functioning in these habitats by studying leaf litter decomposition rates in litter bags placed on the forest floor. The rain forests of Borneo are dominated by trees from the family Dipterocarpaceae, and we compared leaf litter decomposition rates of three dipterocarp species at eight forest fragment sites (area 3–3529 ha) that had different histories of disturbance pre‐fragmentation: four fragments had been selectively logged prior to fragmentation and four had been formed from previously undisturbed forest. We compared these logged and unlogged forest fragments with sites in continuous forest that had been selectively logged (two sites) and fully protected and undisturbed (two sites). After 120 d, undisturbed continuous forest sites had the fastest rates of decomposition (52% mass loss). Forest fragments formed from unlogged forest (32% mass loss) had faster decomposition rates than logged forest fragments (28% mass loss), but slower rates than continuous logged forest (39% mass loss). Leaves of a light‐demanding species (Parashorea malaanonan) decomposed faster than those of a shade‐tolerant species (Hopea nervosa), but decomposition of all three dipterocarp species that we studied responded similarly to logging and fragmentation effects. Reduced decomposition rates in logged and fragmented forest sites may affect nutrient cycling and thus have detrimental consequences for forest regeneration. Conservation management to improve forest quality should be a priority, particularly in logged forest fragments.
