| 摘 要： | 草地生态系统在全球碳循环中起着极为重要的作用。但是实测数据十分匮乏,文中利用2008年全国草原地面监测数据,以及卫星遥感数据,对2008年中国草地的碳储量进行了估算。主要结论如下:中国草地总面积约为341.7×104km2,2008年中国草地总有机碳为35.96Pg,其中地上生物量有机碳为0.1613Pg,地下生物量碳为0.7395Pg,地下根系储存的碳是地上碳储量的5倍左右,中国草地土壤有机碳为35.06Pg。

| Abstract: | Grassland ecosystems plays a very important role in the global carbon cycle.In this paper,based on the ground survey data of grassland in five provinces in 2008 and satellite remote sensing data,carbon storage in grassland ecosystem in China in 2008 was estimated.The main conclusions are as follows: China’s total grassland area was about 331×104hm2.The total carbon storage in grassland ecosystem in China was 35.96 Pg,The carbon storage in aboveground and belowground were 0.1613 and 0.7395 Pg respectively.Carbon storage of underground was about 5 times more than that of aboveground,the soil organic carbon in Chinese grassland was 35.06 Pg. |
