Biomass, productivity and energy use efficiency of climax vegetation on Dinghu Mountains, Guangdong, China

【摘要】 <正> The biomass, primary productivity and energy use efficiency of photosysthetically active radiation of climax vegetation on Dinghu Mountains, in low subtropical were studied with the tree-harvested, litter gather, CO, analysis methods, etc. The results show that the leaf area index of the community is 17; biomass, 363 t·（hm²） ^-1 · a^-1, total productivity, 132 t· （hm²） ^-1 · a^-1; primary productivity, 23.2 t · （hm²） ^-1· a^-1; litter-fall, 9.2t ·（hm²）^-1·a^-1; death tree, 3.9 t·（hm²）^-1· a^-1, animal-eating, 0.6 t·（hm²） ^-1 · a^-1; net productivity, 9.5 t·（hm²）^-1· a^-1.更多还原
