摘要
稳定性同位素是天然示踪剂,在研究植物水分溯源、植物的生长和分布、水分的可利用程度等方面具有独特优势。为了更好地促进稳定性同位素在沙区植物研究中的应用,介绍了应用稳定性同位素技术在研究固沙植被水分来源识别中的应用研究进展,梳理了沙区植被水分利用的来源状况,分析了各种植物水分利用模型的优缺点,提出了不同时期不同生态条件下固沙植物具有不同的水分利用策略和效率,以及固沙植物对水源的利用研究待加强的方向,以期能为国内沙区植物水分利用研究提供参考。
Stable isotopes are natural tracers and have unique advantages in studying plant water sources,plant growth and distribution,and water availability.In order to better promote the application of stable isotopes in the study of plants in sand areas,this paper introduces the progress of the application of stable isotope technology in the study of water source identification of sand fixation vegetation,sorts out the sources of water use of vegetation in sand areas,and analyzes the advantages and disadvantages of various plant water use models.It is pointed out that sand-fixing plants have different water utilization strategies and efficiency under different ecological conditions in different periods,and the research direction of water utilization by sand-fixing plants should be strengthened,in order to provide reference for the study of plant water utilization in sand areas in China.
