一項(xiàng)深入研究亞馬遜雨林歷史的研究發(fā)現(xiàn)，原住民在此居住了數(shù)千年，卻 “沒有造成明顯的物種損失或干擾”。

This was an exercise in botanical archaeology, with the researchers examining layers of rainforest soil excavated in a remote corner of northeastern Peru. They dated each layer and studied the microscopic plant fossils locked inside. This revealed that there had been little change in the composition of plants growing in this part of the rainforest for 5,000 years before Europeans arrived in the Amazon.

這是一個(gè)植物考古學(xué)的課題，研究人員們檢驗(yàn)了在秘魯東北部偏遠(yuǎn)角落挖掘出來的雨林土壤層。他們推算出了每層土壤的年代，并研究了鎖在其中的微型植物化石。結(jié)果表明，在歐洲人到達(dá)亞馬遜地區(qū)以前的五千年內(nèi)，生長在這片雨林中的植物成分幾乎沒有變化。

Previous research has suggested that the rainforest was intensively managed and modified by indigenous peoples. But this evidence suggests that people lived for millennia among the Amazon’s biodiversity without disturbing it.

過去的研究認(rèn)為，這片雨林曾被各原住民族密集地監(jiān)管和改造。但最新的證據(jù)表明，原住民在生物種類多樣的亞馬遜地區(qū)生活了數(shù)千年，卻未對(duì)其造成干擾。

That indigenous knowledge, for example, about which species thrive best in which locations, could be vital in helping modern conservationists to protect what’s now a landscape under threat.

原住民掌握的知識(shí)，比如哪些物種最適合在哪些地方繁衍生息，對(duì)幫助當(dāng)下的保育人士維護(hù)這一現(xiàn)面臨威脅的自然景觀來說，可能是至關(guān)重要的。
