| 摘 要： | 采用Sunscan冠层分析仪,对库布齐固定沙地、半固定沙地、流动沙地油蒿群落冠层光合有效辐射截获量(IPAR)进行研究,分层测量地上生物量重量.结果表明库布齐沙地不同沙地类型IPAR固定沙地＞半固定沙地＞流动沙地,不同沙地油蒿群落冠层IPAR与地上生物量具有显著相关性,冠层截获的光合有效辐射增加,固碳量加大,固碳能力提高. |
| 关 键 词： | 库布齐沙地 油蒿 冠层光合有效辐射截获量 地上生物量 |

| Abstract: | The photosynthetic active radiation in canopy of Artemisia ordosica community in Kubuqi fixed sandland,semi-fixed sandland and drifting sandland were measured with the Sunscan canopy analysis system.The results showed that canopy photosynthetic active radiation in canopy of Artemisia ordosica community was fixed sandland>semi-fixed sandland >drifting sandland.The canopy structure of Artemisia ordosica community on different sandland was significant correlated to dry matter weight,photosynthetic active radiation intercepted by canopy increased,the amount of carbon fixed increased,fixed carbon capability was enhanced. |
