中文摘要	采用野外取样与室内分析相结合的方法,对内蒙古锡林郭勒3种草原类型中67种植物的碳含量,以及碳含量和热值的相关关系进行了研究。结果表明,67种植物的碳含量呈正态分布。基于生活型分类群的碳含量(%)平均值从小到大依次为:一二年生植物(49.392.88)<多年生杂草(52.311.65)<半灌木(52.841.90)<多年生禾草(53.540.88),一二年生植物碳含量显著低于其他类群(P<0.05),其他3个类群之间没有显著性差异(P>0.05)。基于水分生态类型的碳含量(%)平均值从小到大依次为:旱中生植物(50.014.36)<中生植物(51.801.92)<湿中生植物(51.960.78)<旱生植物(52.341.90)<中旱生植物(52.541.53),不同水分生态功能群之间的碳含量无显著性差异(P>0.05)。在基于科的分类群的碳含量中,不同科的植物之间差异显著(P<0.05),其中:藜科植物的碳含量最低,仅为(48.432.65)%。碳含量与热值呈现显著的正相关关系(r=0.52,P<0.01)。
英文摘要	The carbon content is a metric of plant carbon storage, which reflects the ability to fix and store carbon element in photosynthesis of the green plants, is also one of important indexes to estimate carbon storage of ecosystem. The carbon contents, and their relationships with the calorific values of 67 plant species in three types from different climate zones of Xilin Gol Grassland (meddow steppe, typical steppe, desert steppe), Inner Mongolia were studied with the method of the field sampling and experimental determination, and the carbon content variation of different plant functional groups based on several classification method were studied at the same time. The aim is to provide theoretical basis for estimating scientifically carbon storage of grassland ecosystems. The results showed that the carbon content in the 67 species of plants were in normal distribution, the average value was (52.172.01)%, of all the species, the Salsola collina, a kind of annual forb, had the lowest value (43.791.37)%, and Thalictrum squarrosum, a kind of perennial forb, had the highest value (57.124.58) %. Among the groups classified by life forms, the order of average carbon content (%), from low to high, was: annuals and biennial plants (49.392.88)0.05). The carbon contents (%) of the different plant groups based on water ecological types, followed the order: xero mesophyte (50.014.36)0.05). Different families showed apparent difference in average carbon content (P<0.05), the lowest value was found in Chenopodiaceae, only (48.432.65)%. And there was a positive correlation between the carbon contents of 67 species and their calorific values (r=0.52, P<0.01).
