Investigating the forest biomass allocation is crucial for understanding the impacts of global change on carbon allocation and cycling.Moreover, the question of how climate factors affect biomass allocation in natural and planted forests remains unresolved. Here, we addressed this question by collecting data from 384 planted forests and 541 natural forests in China. We evaluated the direct and indirect effects of climate factors on the belowground biomass proportion(BGBP). The average BGBP was 31.09% in natural forests and was significantly higher(38.75%) in planted forests. Furthermore, we observed a significant decrease in BGBP with increasing temperature and precipitation. Climate factors, particularly those affecting soil factors, such as p H,strongly affected the BGBP in natural and planted forests. Based on our results, we propose that future studies should consider the effects of forest type(natural or planted) and soil factors on BGBP.展开更多
