中文摘要	植物的稳定碳同位素组成(delta~(13) C)能反映植物对干旱环境的适应能力。为研究荒漠草原区猪毛蒿(Artemisia scoparia)的生存策略,本研究以猪毛蒿为试验对象,分析了猪毛蒿同化枝delta~(13) C值与土壤因子,种群数量特征,以及猪毛蒿个体生物量分配间的关系。结果表明:猪毛蒿同化枝delta~(13) C值分布为29.76~25.10。试验区内土壤体积含水率、土壤硬度对猪毛蒿同化枝delta~(13) C的影响不显著。delta~(13) C值与密度呈显著负相关关系(P<0.05),与盖度、株高和冠幅呈极显著正相关关系(P<0.01)。delta~(13) C值与营养器官生物量、繁殖器官生物量、地上生物量、地下生物量和总生物量均呈极显著正相关关系(P<0.01);猪毛蒿营养器官生物量与繁殖器官生物量呈极显著正相关(P< 0.01)。综上可得,猪毛蒿同化枝delta~(13) C值与植株种群数量特征、个体生物量分配存在明显的相关性,表明猪毛蒿为适应荒漠草原环境,能够采取独特的生存适应策略。
英文摘要	The stable carbon isotope composition (delta~(13) C)of plants reflects the adaptability of plants to drought environment.To study the survival strategy of Artemisia scopariain desert steppe region,Artemisia scoparia was used as the test object,and the relationship amongdelta~(13)C values,the soil factors,quantitative characteristics of population,and individual biomass allocation of Artemisia scoparia were analyzed. The results showed that thedelta~(13)C values of assimilation branch of Artemisia scoparia was distributed at 29.76~25.10.The volumetric water content of soil and soil hardness had no significant effect on thedelta~(13)C values of assimilation branch of Artemisia scoparia.The correlation ofdelta~(13) C values with density was significantly negative(P <0.05).The relationships ofdelta~(13) C values with coverage,plant height and crown width was significantly positive(P<0.01).Thedelta~(13)C values were significantly positively correlated with vegetative organ biomass,reproductive organ biomass,aboveground biomass,underground biomass and total biomass(P<0.01).There was a significantly positively correlation between vegetative organ biomass and reproductive organ biomass of Artemisiascoparia (P<0.01).In summary,there was a clear correlation among thedelta~(13)C values of assimilation branch of Artemisia scoparia,quantitative characteristics of population,and individual biomass allocation,indicating that Artemisia scoparia had an unique survival adaptation strategy to the desert steppe environment.
