Water table drawdown increases plant biodiversity and soil polyphenol in the Zoige Plateau

Water table drawdown accelerates peatland degradation and carbon loss from peatland, but phenolic compounds—the concentration and composition of which are determined by vegetation community composition—can slow down carbon loss. However, the response of phenolic compounds to water table drawdown is...
