死亡速度加快数倍澳大利亚和美国的研究人员最近的研究结果表明,全球1 00年~300年树龄的大型树木目前正在以惊人的速度濒临灭绝。大洋洲的花楸、美洲的松树、红木和非洲的猴面包树等树种面临风险(图1),它们不仅在森林大火中大规模死亡,而且在没有火灾的年份里死亡速度也是正常速度的10倍最大的活的有机体古树和巨树是地球上最大的活的有机体(图3),在森林、林地、热带稀树草原、农业景观和城市地区呈阶梯形结构,起到年幼、较小树木无法发挥的独特的生态作用。大型树木以水果、花、叶 The rate of death is several times faster Recent research by researchers in Australia and the United States has shown that large-scale trees of 100 years to 300 years of age worldwide are now extinct at an alarming rate. Trees in Oceania, pine trees in the Americas, mahogany and African baobab are at risk (Figure 1), not only on a large scale in forest fires, but also in death-free periods at rates 10 times normal The Largest Living Organisms The ancient trees and giant trees are the largest living organisms on the planet (Figure 3), featuring a ladder-like structure in forests, woodlands, savannas, agricultural landscapes and urban areas, serving young, smaller The unique ecological role that trees can not play.
