| 摘 要： | 茎流是大气降水与溶解物在植物茎干上的汇集与运移,它对森林和农业生态系统具有重要的水文学和生态意义。本文总结了前人研究成果,加深了对茎流的理解并找出缺陷与误区,以促进对薄弱环节的研究。探讨了气象条件,季节变化,覆被结构,冠层空间型及植被种别等多个复杂易变因素对茎流量和其化学成分的影响。

| Abstract: | Stemflow is formed by converging and transferring precipitation and solutes in plant stem,which is of hydrologic and ecological significance in forest and agricultural ecosystem.The paper reviewed the prevenient study,and furthered comprehension of stemflow and found out the limitation and insufficiency.Then,the influence of meteorological conditions,seasonality variation,canopy structure,interspecific and intraspecific variation on stemflow yield and chemistry were discussed. |

| Keywords: | stemflow forest and agricultural ecosystem forest and agricultural hydrology nutrition cycling |
