[Responses of radial growth of at different densities to drought events].

In recent years, a surge in drought occurrences has dramatically impacted tree growth worldwide. We examined the ecological resilience of plantations with varying densities (1950, 2355, and 2595 trees·hm) at the Saihanba Mechanical Forest Farm, by extracting the increment cores using the standard dendrochronological method to measure individual-tree basal area increments (BAI) as part of our assessment of ecological resilience, including resistance (), recovery (), and resilience (). The results showed that drought events occurred in 2006-2010, 2015, and 2018.
