氢氧稳定同位素在森林雾水研究中的应用及展望

Application of Oxyhydrogen Stable Isotope Technology on Research of Fog Water in Forest

雾水是森林生态系统中水平降水的重要组成之一,利用灵敏度高且可定量化测定的稳定同位素技术,分析雾水在森林生态系统水循环中的作用,是目前森林水文研究的热点。从林冠截留雾水、森林对雾水的利用情况以及雾水对森林土壤水、地下水的补给等方面进行综述,以期为运用氢氧稳定同位素技术研究多雾山地生态系统和海滨生态系统中的森林生态水文效应提供参考。

Fog is one of the important parts of horizontal precipitation in forest ecosystem.Based on stable iso-tope technique with high sensitivity and quantification is the focus research of forest hydrology to analyze the role of fog water in the water cycle in forest ecosystem.The paper summarized the canopy interception fog,forests utiliza-tion of fog water and fog water recharge soil water and groundwater,provided a reference for the use of hydrogen and oxygen stable isotope technique to study the foggy mountain ecosystem and coastal ecosystem in the forest hydrological effects.
