中文摘要	本文研究了宁夏草甸草原、温性草原、草原化荒漠和荒漠草原4种温性典型天然草地生态系统碳储量及其构成特征。结果表明:草甸草原、温性草原、草原化荒漠和荒漠草原植被总生物量分别为1178.91、481.22、292.80和209.09 g·m~(-2)。其中,地下根系生物量是构成草甸草原和温性草原植被总生物量的主体,分别占总生物量的73.1%和56.6%;地上植被生物量是构成草原化荒漠和荒漠草原植被总生物量的主体,分别占总生物量的50.3%和47.6%;枯落物生物量占比较低,分别仅为8.5%、8.0%、6.4%和16. 2%。草甸草原、温性草原、草原化荒漠和荒漠草原4种天然草地生态系统碳储量分别为13.90、5.94、2.69和2.37 kg·m~(-2),其中植被碳储量分别为470.26、192.23、117.17、83.36 g·m~(-2),0 ~ 40 cm土层土壤有机碳储量分别为13.43、5.75、2.58和2.29 kg·m~(-2),土壤有机碳储量是构成宁夏典型天然草地碳储量的主体,分别占到了生态系统碳储量的96.6%、96.8%、95.6%和96.5%。 4种草地类型植被总生物量、植被碳储量、土壤有机碳储量和生态系统碳储量均表现为:草甸草原>温性草原>草原化荒漠>荒漠草原。
英文摘要	To accurately estimate ecosystem carbon storage of natural grassland in Ningxia,we examined ecosystem carbon storage in four types of typical temperate natural grasslands,including meadow steppe,warm steppe,steppe desert,and desert steppe in Ningxia. The results showed that the total vegetation biomass of meadow steppe,warm steppe,steppe desert and desert steppe were 1178.91,481.22,292.80 and 209.09 g·m~(-2),respectively. Root biomass was the main component of total vegetation biomass of meadow steppe and warm steppe,with a contribution of 73.1% and 56.6%,respectively. Aboveground biomass was the main component of total vegetation biomass of steppe desert and desert steppe,accounting for 50.3% and 47.6%,respectively. Litter made low contribution,being 8.5%,8.0%,6.4% and 16.2%,respectively. Ecosystem carbon storage of four typical natural grassland was 13.90,5.94,2.69 and 2.37 kg·m~(-2),vegetation carbon storage was 470.26,192.23,117.17 and 83.36 g·m~(-2),and soil organic carbon storage in 0-40 cm layers were 13.43,5.75,2.58 and 2.29 kg·m~(-2),respectively. Soil organic carbon storage was the main body of the total carbon storage of four typical natural grassland in Ningxia,accounting for 96.6%, 96.8%,95.6% and 96.5%,respectively. The total vegetation biomass,vegetation carbon storage, soil organic carbon storage and ecosystem carbon storage of four natural grassland types were in the order of meadow steppe>warm steppe>steppe desert>desert steppe.
