在阿尔伯兹山脉（Hyrcanian森林上方）的吉兰省高地，首次重建了过去4,300 cal yrsbp的植被、火灾和气候动态以及人类影响。本文应用花粉、孢子、非花粉孢粉、木炭和地球化学分析等多种代用指标分析方法，研究了2,280 m a.s.l.在赫坎尼亚森林上空主导草原植被发生在整个记录期间的研究领域。所研究的沼泽沉积物的形成以及植被组成表明，在4，300至1，700 calyrsbp之后，气候条件变得更加湿润。火灾频繁，这可能意味着该地区长期存在人类活动。植被覆盖减少，水分指数（MI）显著下降，表明干燥条件介于1，700和1，000 cal yrsbp之间。在低海拔地区，菊苣亚科和苋科的比例很高，树木减少，特别是水青冈属和栎属，表明人类活动，如密集的牲畜放牧和砍伐森林。土壤侵蚀是由于干旱和人类活动导致植被减少的结果，可以从Glomusspores的显着增加和高值的K和Ti重建。自1，000 cal yrsbp以来，MI增加，以及禾本科和莎草科的兴起以及森林恢复，表明向更潮湿的条件变化。仍然频繁发生的菊苣亚科和车前lanceolata随着Sordariareflect继续密集放牧的牲畜由人类。
Past vegetation, fire, and climate dynamics, as well as human impact, have been reconstructed for the first time in the highlands of the Gilan province in the Alborz mountains (above the Hyrcanian forest) for the last 4,300 cal yrsbp. Multi-proxy analysis, including pollen, spores, non-pollen palynomorphs, charcoal, and geochemical analysis, has been applied to investigate the environmental changes at 2,280 m a.s.l., above the Hyrcanian forest. Dominant steppe vegetation occurred in the study area throughout the recorded period. The formation of the studied mire deposits, as well as vegetation composition, suggest a change to wetter climatic conditions after 4,300 until 1,700 cal yrsbp. Fires were frequent, which may imply long-lasting anthropogenic activities in the area. Less vegetation cover with a marked decrease of the Moisture Index (MI) suggests drier conditions between 1,700 and 1,000 cal yrsbp. A high proportion of Cichorioideae and Amaranthaceae, as well as the reduction of trees, in particularFagusandQuercus, at lower elevations, indicate human activities such as intense livestock grazing and deforestation. Soil erosion as the result of less vegetation due to dry conditions and/or human activities can be reconstructed from a marked increase ofGlomusspores and high values of K and Ti. Since 1,000 cal yrsbp, the increasing MI, as well as the rise of Poaceae and Cyperaceae together with forest recovery, suggest a change to wetter conditions. The occurrence of still frequent Cichorioideae andPlantago lanceolataalong withSordariareflect continued intense grazing of livestock by humans.
