摘要
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·(hm^2)^(-1)· a^(-1), total productivity, 132 t· (hm^2)^(-1) · a^(-1); primary productivity, 23.2 t · (hm^2)^(-1)· a^(-1); litter-fall, 9.2t ·(hm^2)^(-1)·a^(-1); death tree, 3.9 t·(hm^2)(-1)· a^(-1), animal-eating, 0.6 t·(hm^2)^(-1) · a^(-1); net productivity, 9.5 t·(hm^2)^(-1)· a^(-1).
