Guangxi Pingxiang BEF
The experiment was established in Pingxiang, Guangxi, China, in 2015. The main objective is the selection of tree species composition patterns to enhance forest productivity, ecosystem carbon stock and stability, biodiversity, and soil nutrient retention, as well as to understand the mechanisms involved in these processes.
Design
The experiment includes 5 tree species and consists of 4 random blocks, each with 12 treatments and each treatment has 4 replicates. Tree species richness levels are 0, 1, 2, and 4. There are five types of monoculture, four types of 2-species mixture, and two types of 4-species, and additional 4 plots without plantings and natural restoration. The species are mixed by rows.

Research
The experiment aims to:
1. Clarify the mechanisms by which tree species diversity and stand structure affect carbon storage and its composition in forest ecosystems.
2. Investigate the relationship between aboveground and belowground carbon storage in forest ecosystems and its driving mechanisms.
3. Unveil the dominant mechanisms behind carbon sequestration enhancement and the trade-offs and synergies of multiple functions in forest ecosystems.
