| 摘 要： | 本文重点阐述了稳定性同位素18O和D在生态-水文过程研究中的研究进展,主要包括植物水分来源与比例、土壤水分动态变化与植物根系吸水、干旱区水分转化与补给等方面的研究成果。并针对我国干旱区生态水文过程研究中的具体问题,指出在今后应加强利用稳定性同位素技术在荒漠植被不同水分来源识别、植物水-地下潜水-土壤水-大气降水的转化过程、干旱区降水对不同尺度范围土壤水分和地下潜水的转化补给、具有水力提升和逆水力提升功能植物识别等方面研究中的应用。

| Abstract: | This review emphasized on the advances in the applications of 180 and D in the study of eco - hydrological progress research, mainly including the water sources and proportions of plants, mechanisms of water movement in soil and water absorption by plant roots, water transferring and replenishment in arid regions, and etc. Through analyzing the existing issues in eco - hydrological progress researches of arid regions in China, we point out that aftertime it should be strengthened the application of the stable isotope technique in the fields of identify of plant water sources,conversion progress among plant water - groundwater - soil water - precipitation, identify hydraulic lift and inverse hydraulic lift by plants,precipitation in arid region in different scale for soil water and groundwater recharge and transform and so on. Along with the development of isotopes measurement levels, isotopic techniques will be used in wider field eco -hydrological progress in arid regions and will be achieved more advance. |
