| 中文摘要 | 根据定位观测数据和有关历史资料，研究了贡嘎山东坡峨眉冷杉（Ａｂｉｅｓｆａｂｒｉ）近熟林和中龄林Ｃ循环。测定了两种林分植物Ｃ储量、土壤有机Ｃ储量、凋落物和立枯量中的Ｃ储量，并对两种林分的净光合速率进行了对照研究。 |
| 英文摘要 | The carbon cycle ,especially the CO2 emission and uptake by the middle age and near mature A bies f abri forest s was studied in this paper . The forest CO2 source and sink were emphatically analyzed . Based on the data of located observation on the east slope of Gongga Mountain , the following aspect s were investigated in the middle age and near mature A bies f abri forest s : the storage of plant s carbon , soils organic carbon , litter and dead standing t ree carbon , photosynthetic rates of the plant s and respiration rates of the plant s and soils by CI - 301 photosynthesis system. The result s show that the total carbon storage of the near mature forest was 320. 966 t/ hm2 ,of which , the storage of plant carbon ,soil organic 2 期罗辑等:贡嗄山东坡峨眉冷杉林C循环的初步研究 253 carbon , litter and dead standing t ree carbon accounted for 172. 740 , 143. 152 , 1. 786 and 3. 288 t/ hm2 , respectively. The total carbon storage of middle age forest was 98. 465 t/ hm2 , of which ,the storage of plant carbon , soil organic carbon , litter and dead standing t ree carbon ac2 counted for 57. 966 , 30. 698 , 1. 504 and 8. 297 t/ hm2 , respectively. CO2 was released which a rate of 21. 749 t/ hm2·a f rom the soil of the near mature forest . CO2 was released with a rate of 12. 320 t/ hm2·a f rom the soil of the middle age forest . The result s also show that there was an increasing in carbon storage of the middle age and near mature forest s f rom atmospheric CO2 . The main factor which affected soil respiration was temperature. Finally ,the uncertainties in the estimations were discussed in detail and further works were also suggested. |
