西部中国沙棘叶片稳定碳同位素组成的空间特征及其气候意义

摘要/Abstract

摘要： 分析了西部中国沙棘（Hippophate rhamnoides sinensis）叶片稳定碳同位素组成特征及其与环境因子之间的关系。结果表明,中国沙棘叶片δ13C值在-30.40‰~-24.91‰之间变化,平均值约为-27.62‰,属于C3植物。随纬度和经度的升高,中国沙棘叶片δ13C值明显升高,而随海拔的升高而降低,具有明显的空间分布特征。中国沙棘叶片δ13C值与温度没有明显的关系,随蒸发量和日照时间的升高而升高,随降水量的升高有降低趋势,具有明显的气候意义。表明中国沙棘具有较高的水分利用效率,水分是控制中国沙棘δ13C值变化或生长的主导因子。

Abstract: Analysis on the relation between stable carbon isotope composition in Hippophate rhamnoides sinensis leaves and environmental factors was conducted in this study. Results showed that the leaf carbon isotope values ranged from -30.40‰ to -24.91‰, averaging -27.62‰, indicating the Hippophate rhamnoides sinensis species belongs to C3 plant. The δ13C values of Hippophate rhamnoides sinensis has obvious spatial distribution characters, increasing with the increase of latitude and longitude, and decreasing with the increase of altitude. The δ13C values of Hippophate rhamnoides sinensis increase with the increase of evaporation and sunshine duration, and tend to decrease with the increase of precipitation, having considerable climate-indicating significance. The results also showed that the Hippophate rhamnoides sinensis has high water use efficiency and water is the main factor controlling its growth and the variation of foliar stable carbon isotope composition.

Key words: Hippophate rhamnoides sinensis, δ¹³C, environmental factors
