| 摘 要： | 植被净初级生产力（NPP）作为重要的植被参数和生态指标,能够直观地反映生态环境的变化和区域碳收支水平。鉴于三江源特殊的地理环境和战略地位,众多学者曾应用不同的方法对三江源植被NPP进行了估算,但是由于各方面原因,NPP估算结果存在较大差异。目前,虽在三江源地区开展了大量NPP估算研究,但尚未有相关文章对这些研究进行汇总并加以分析和评价。因此,本文在前人研究成果的基础上,通过综述已有文献,对三江源植被NPP估算的相关方法与结果进行了系统地总结,探讨不同方法在三江源地区的适用性,指出已有方法存在的主要问题,并对现有NPP估算结果进行评估分析,最后提出了未来三江源NPP估算研究亟待加大研究力度的方向。

| Abstract: | As the "Water Tower of China", the Three-River Headwater Region (TRHR) is an important ecological shelter for national security and regional sustainable development for many Southeast Asian countries and the middle or lower reaches of main rivers in China. The TRHR has typical high and cold environment and alpine vegetation system. Net primary productivity (NPP), as a key vegetation parameter and ecological indicator, can reflect the natural environment change and the carbon budget level intuitively. Given the particular geographic environment and strategic position of the TRHR, many scholars have estimated NPP of the TRHR using different methods. For various reasons, however, the estimated NPP varies greatly. At present, a great deal of research involving NPP estimation has been conducted on the TRHR, but no paper has been published to summarize and assess these studies. Therefore, this paper (1) summarized systematically the related methods and results of NPP estimation in the TRHR by review of previous researches; (2) discussed the suitability of existing methods to the TRHR and pointed out the main problems; and (3) assessed the estimated NPP results. Finally, the development directions of NPP estimation in the TRHR were prospected. |
