Soil respiration of a Moso bamboo forest significantly affected by gross ecosystem productivity and leaf area index in an extreme drought event.

ABSTRACT: Moso bamboo has large potential to alleviate global warming through carbon sequestration. Since soil respiration (R _s ) is a major source of CO₂ emissions, we analyzed the dynamics of soil respiration (R _s ) and its relation to environmental factors in a Moso bamboo (Phllostachys heterocycla cv. pubescens) forest to identify the relative importance of biotic and abiotic drivers of respiration. Annual average R _s was 44.07 t CO₂ ha^-1 a^-1. R _s correlated significantly with soil temperature (P < 0.01), which explained 69.7% of the variation in R _s at a diurnal scale. Soil moisture was correlated significantly wit
