概括

水平衡方法 (WBM) 最准确地测量了草拦截,与擦水和浸水方法不同. 叶面积和叶面接触角度显著影响草的拦截能力.

科学领域:

水文和生态工程水文和生态工程
植物生理学和生物气象学

背景情况:

植被对天花板的拦截对于水文过程至关重要,如透,下水和蒸发.
有限的研究存在于草拦截,有显著的方法差异阻碍了比较分析.

研究的目的:

为了研究五种常见的温带草种的树冠拦截特征.
为了比较三种实验方法的准确性:水平衡方法 (WBM),擦水方法 (WWM) 和浸水方法 (WIM).
为了确定影响草截获的关键因素.

主要方法:

在实验室环境中培养了五种斜坡保护草种.
使用WBM,WWM和WIM实验测量了天花板拦截.
采用灰色相关性分析来确定八个因素对天花板拦截的影响.

主要成果:

与WWM和WIM相比,WBM提供了明显更高和更准确的草拦截测量.
叶面被确定为影响树冠拦截的最关键因素,其次是降雨量和干质量.
天花板拦截能力与降雨量呈负功率函数关系,降雨强度达到每小时15-20毫米的峰值.

结论:

WBM是量化草截获的最可靠方法.
叶子接触角是一个关键参数,解释了树冠拦截能力的物种间差异.
这些发现增强了对草拦截的理解,并指导实验方法的选择.

关键词:

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
