Litter input is a critical link between the circulation and flows of energy matter in forest ecosystems. Drought events impact litter inputs, affecting ecosystems' nutrient cycles. To investigate response production to extreme drought, explore their recovery mechanism, difference whole year, concurrent non-drought period, rainy season, dry season. We studied an drought event subtropical evergreen broadleaved Ailao Mountain 2009–2010. used 10 years (2005–2014) monthly climate data, including average precipitation (MAP), soil water content (SWC), temperature (MAT). The observation period was separated into pre-drought (2005–2008), during-drought (2009–2010), post-drought (2011–2014) periods. found that annual total decreased by 12 % during (p < 0. 05), similar period. Leaf increased 1 time, other fraction obviously. contribution environmental factors more evident after events. MAT, MAP, SWC jointly affect under conditions, dominant factor related Water (MAP & SWC) contributed events, while MAT mainly affected seasons. Due growth nutritional strategies each fraction, time branch leaf flower fruit moss bark. results further reveal importance recovery.
