荷兰瓦赫宁根大学Lourens Poorter团队研究了多维热带森林恢复过程。2021年12月10日出版的《科学》杂志发表了这项成果。
他们使用热带地区的 77 个站点分析了 12 种森林属性在次生演替过程中如何恢复以及它们的恢复如何相互关联。热带森林对低强度土地利用具有很强的复原力； 20 年后，森林属性达到其原始生长值的 78%（33% 至 100%）。土壤（<10年）和植物功能（<25年）恢复到旧生长值的 90% 最快，结构和物种多样性介于中间（25到60年），生物量和物种组成最慢（>120年）。
网络分析显示了三个独立的属性恢复集群，与结构、物种多样性和物种组成有关。次生林应被视为生态系统恢复、减缓气候变化和生物多样性保护的低成本、自然解决方案。
据了解，由于森林砍伐，热带森林迅速消失，但它们有可能在废弃的土地上自然再生。

Abstract: Tropical forests disappear rapidly because of deforestation, yet they have the potential to regrow naturally on abandoned lands. We analyze how 12 forest attributes recover during secondary succession and how their recovery is interrelated using 77 sites across the tropics. Tropical forests are highly resilient to low-intensity land use; after 20 years, forest attributes attain 78% (33 to 100%) of their old-growth values. Recovery to 90% of old-growth values is fastest for soil (<1 decade) and plant functioning (<2.5 decades), intermediate for structure and species diversity (2.5 to 6 decades), and slowest for biomass and species composition (>12 decades). Network analysis shows three independent clusters of attribute recovery, related to structure, species diversity, and species composition. Secondary forests should be embraced as a low-cost, natural solution for ecosystem restoration, climate change mitigation, and biodiversity conservation.
