| 英文摘要 | Analysis of stable isotope composition is an important tool in research on plant physiological ecology. However, large-scale patterns of leaf-stable isotopes for aquatic macrophytes have received considerably less attention. In this study, we examined the spatial pattern of stable isotopes of carbon (delta C-13) and nitrogen (delta N-15) of macrophytes leaves collected across the arid zone of northwestern China (approximately 2.4 x 10(6) km(2)) and attempted to illustrate its relationship with environmental factors (i.e., temperature, precipitation, potential evapotranspiration, sediment total carbon and nitrogen). Our results showed that the mean values of the leaf delta C-13 and delta N-15 in the macrophytes sampled from the arid zone were -24.49 parts per thousand and 6.82 parts per thousand, respectively, which were far less depleted than those measured of terrestrial plants. The order of averaged leaf delta C-13 from different life forms was as follows: submerged > floating-leaved > emergent. Additionally, our studies indicated that the values of foliar delta C-13 values of all the aquatic macrophytes were only negatively associated with precipitation, but the foliar delta N-15 values were mainly associated with temperature, precipitation, and potential evapotranspiration. Therefore, we speculated that water-relation factors are the leaf delta C-13 determinant of macrophytes in the arid zone of northwestern China, and the main factors affecting leaf delta N-15 values are the complex combination of water and energy factors. |
