| 摘 要： | 对贡嘎山亚高山森林生态系统草地亚系统冰川退缩9年迹地形成的小叶黄芪群落C循环进行了研究.根据植物固定的有机碳量、土壤有机碳储量和土壤CO2呼吸量,结合群落区域大气温度与土壤CO2排放关系, 研究得出贡嘎山亚高山森林生态草地亚系统小叶黄芪群落C循环周期为88年,是CO2循环的库.

| Abstract: | The carbon cycle was studied for an Astragalus hulunensis population in the grassland sub-system of the sub-alpine forest ecosystem on Mt. Gongga, the population forming on exposed land with glacier retreat for 9 years. Looking at plant organic carbon sequestration, soil organic carbon reserves, and soil CO_2 emission, in combination with the relationship between atmospheric temperature and soil CO_2 emission, the results showed that the carbon cycle of the Astragalus hulunensis population is 88 years, and the population is a pool for carbon-dioxide cycling. |
