Experiments under controlled conditions have established that ecosystem functioning is generally positively related to levels of biodiversity, but it is unclear how widespread these effects are in real-world settings and whether they can be harnessed for ecosystem restoration. We used remote-sensing data from the first decade of a long-term, field-scale tropical restoration experiment initiated in 2002 to test how the diversity of planted trees affected recovery of a 500-ha area of selectively logged forest measured using multiple sources of satellite data. Replanting using species-rich mixtures of tree seedlings with higher phylogenetic and functional diversity accelerated restoration of remotely sensed estimates of aboveground biomass, canopy cover, and leaf area index. Our results are consistent with a positive relationship between biodiversity and ecosystem functioning in the lowland dipterocarp rainforests of SE Asia and demonstrate that using diverse mixtures of species can enhance their initial recovery after logging.
在受控条件下进行的实验已经证实，生态系统功能通常与生物多样性水平呈正相关，但目前尚不清楚这些影响在现实环境中广泛程度如何，以及它们是否可以用于生态系统恢复。我们使用了 2002 年启动的一项长期野外尺度热带恢复实验的第一个十年的遥感数据，以测试种植树木的多样性如何影响使用多种卫星数据源测量的 500 公顷被选择性采伐森林的恢复。使用具有更高系统发育和功能多样性的树种丰富混合物进行重新种植，加速了对地上生物量、冠层覆盖和叶面积指数的遥感估算的恢复。我们的结果与东南亚低地龙脑香雨林中生物多样性与生态系统功能之间的正相关关系一致，并表明使用多种物种的混合可以增强它们在采伐后的初始恢复。
