摘要(Abstract)：

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。利用2008年四川省草原地面调查数据,以及卫星遥感数据,对2008年四川省草地的碳储量进行了估算。主要结论如下:四川省草地总面积约为20.38×10⁴ km²,2008年四川省草地总有机碳为2 302.97 Tg,其中地上生物量有机碳为15.54 Tg,地下生物量碳为104.45 Tg,地下根系储存的碳是地上碳储量的6倍多,四川省草地土壤有机碳为2 182.98 Tg。土壤储存的碳是植被的19倍多。
The grassland ecosystem plays a very important role in the global carbon cycle. But the measured data is very lacking. In this paper,based on the ground survey data of the grassland in 2008 and satellite remote sensing data in Sichuan,the carbon storage in grassland ecosystem in Sichuan was estimated. The results showed that the total grassland area in Sichuan was about 22.43×10⁴ km² in 2008, and the total carbon storage in the grassland ecosystem in Sichuan was 2 302.97 Tg. The aboveground and underground carbon storage was 15.54 and 104.45 Tg C respectively. The underground carbon storage was about 6 times more than the aboveground; the soil organic carbon in Sichuan grassland was 2 182.98 Tg, which was about 19 times more than the vegetation carbon.
