| Abstract: | The biomass and net productivity of typical forest stand dominant species Picea crassifolia and Sabina przewalskii at different average age in the Qilian Mountains were studied.The results showed that the biomass of Picea crassifolia was 282.544 t/hm2,the biomass of Sabina przewalskii was 248.764 t/hm2,different organs biomass distribution size sequence of Picea crassifolia and Sabina przewalskii were trunk(61.19%,58.82%)>root(28.17%,22.73%)> branch(6.47%,14.15%)> leaves(2.77%,2.83%)> fruit(1.40%,1.47%);net primary productivity were 5.249 and 5.280 t/(hm2·a) of Picea crassifolia and Sabina przewalskii,its annual die litter quantity and each organ in growth size were litter(39.09%,43.45%) > fruit(24.77%,22.73%) > trunk(16.66%,15.02%)> branch(8.70%,11.33%)> root(7.05%,5.07%)> leaves(3.73%,2.40%). |
