| 英文摘要 | High-resolution pollen and charcoal records from two bogs-Stavs & aring;kra in the hemiboreal zone and Storasj & ouml; in the boreal zone of central Sm & aring;land, southern Sweden-were used to reconstruct Holocene plant diversity and to disentangle the relative impacts of climate, fire, and anthropogenic disturbance. Four diversity metrics (richness, evenness, Simpson index, and Shannon-Wiener index) were applied to reconstruct plant diversity. Richness declined from 11 to 9.2 ka BP, remained low and variable between 7 and 3 ka BP, and increased again after 3 ka BP. These long-term trends track regional climate change. Superimposed centennial-scale variability was early Holocene, which maintained open canopies and high biodiversity. On the contrary, low fire frequency at Storasj & ouml; promoted closed conifer forests and lower diversity. The mid-Holocene low-fire regime at Stavs & aring;kra decreased evenness, whereas moderate fire disturbance at Storasj & ouml; sustained mixed forests. After 1 ka BP, anthropogenic fires initially enhanced diversity, but ultimately reduced it when burning became excessive. The results corroborate the Intermediate Disturbance Hypothesis: moderate fire frequency maximises plant diversity, whereas both low-fire regime and high-frequency burning depress it. We therefore recommend integrating scientifically monitored prescribed burning into future forest management to restore disturbance regimes and conserve biodiversity in the boreal-hemiboreal landscapes. |
