Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.
