摘要：湿地森林在蓄洪防旱、净化水质等方面对区域水文过程起着重要的调控作用。以往对于淡水湿地森林水文的研究多集中在运用传统水文学方法研究单一水文过程,很少将各水文过程作为一个整体来研究,且各个过程对降水截留效应的影响程度也未全部量化。而利用水分子中天然存在的氢氧稳定同位素作为示踪剂可综合反映并量化植被和土壤对降水的截留能力。文中综述湿地森林对水文过程调控作用的国内外研究概况,探讨氢氧稳定同位素技术在湿地森林水文研究中的进展,包括大气降水、林冠穿透水、降雨径流、土壤水、地下水、蒸发水、植物水的水分来源及各水体的转化关系等。在全球变化背景下,运用氢氧同位素技术系统定量地分析降水在生态系统水文过程的分配比例对于揭示湿地森林植被结构对水文过程的调控机制等具有重要意义,同时也可为建立淡水湿地森林植被恢复模式和制定保护策略提供参考。
Forested wetland plays an important role in regulating regional hydrological process, including flood storage, drought control and water purification. Previous researches on hydrology of freshwater forested wetland are mainly focused on single horological process using traditional horologic methods, and few see these processes as a whole. Furthermore, the influence of these processes on rainfall interception has not been entirely quantified yet. The hydrogen and oxygen stable isotopes, as natural tracers in water molecules, can comprehensively reflect and quantify the ability of vegetation and soil to intercept precipitation. This paper reviewed international and national studies on the regulating role of forested wetland on hydrology process, and discussed the progress in the use of hydrogen and oxygen stable isotopes technology in this field, including atmospheric precipitation, canopy through fall, runoff, soil water, ground water, evaporable water, water source of plants and the conversion relationship among water bodies. Under the context of global climate change, using hydrogen and oxygen stable isotopes to systematically and quantitatively analyze the distribution proportion of precipitation in horological processes of ecosystems is of great significance to reveal the response mechanism of forested wetland to the horological process, and could provide theoretic basis for establishing freshwater wetland forest vegetation restoration model and developing protection strategy.
