Transpiration response of boreal forest plants to permafrost thaw

Transpiration is an important process to quantify because it can be a significant ecosystem water flux and is a major hydrological pathway. The transpiration dynamics of boreal forest plants in permafrost affected regions is relatively understudied, making it difficult to predict how permafrost thaw will impact ecosystem water flux. Thawing permafrost may cause soils to drain in these semi arid systems, making the plants more reliant on precipitation and potentially causing species shifts from those that tolerate cold soil to those that tolerate warm and dry soil. ***Note: Dates are approximate as not listed on poster***蒸腾作用（Transpiration）是一项亟需量化的关键过程，它既是重要的生态系统水通量（Ecosystem Water Flux）组成部分，也是核心的水文循环路径。受多年冻土（Permafrost）影响区域的北方针叶林（Boreal Forest）植物蒸腾动态，目前相关研究仍相对匮乏，这使得我们难以预测多年冻土解冻将如何对生态系统水通量造成影响。在这些半干旱（Semi-Arid）生态系统中，多年冻土解冻可能会引发土壤排水状况改变，导致植物对降水（Precipitation）的依赖程度进一步提升，并可能触发植物物种更替——从适应冷湿土壤的物种，转变为适应暖干环境的物种。 ***备注：因海报未列明具体日期，故相关日期均为近似值***
