Rainfall partitioning in forest canopies and floors-processes, linkages, and scaling issues

野火、虫害、疾病和商业伐木对世界森林面积的影响越来越大，由此产生的影响再加上全球气候变化，使得越来越需要准确的工具，以便水文学家、林业工作者和流域管理人员能够评估干扰和气候对集水产量和生态系统功能的影响。到目前为止，还没有研究探讨不同的干扰类型如何影响森林地面及其水平衡组成部分，信息具有重要的影响野火的潜力。此外，还没有研究探讨林下降雨的空间和时间变化之间的相互作用和不同的干扰和再生情景下土壤水分含量的空间和时间分布。

Wildfire, insect infestation, disease and commercial logging affect progressively larger areas of the world's forests, and resulting effects coupled with global climate change have created an increasing need for accurate tools with which hydrologists, foresters and watershed managers can evaluate disturbance and climate-related impacts on catchment water yield and ecosystem functions. To date, there has been no research examining how different disturbance types affect the forest floor and its water balance components, information that has important implications concerning wildfire potential. Further, there have been no studies examining the interactions between the spatial and temporal variability of understorey rainfall and the spatial and temporal distribution of soil moisture contents under different disturbance and regrowth scenarios.
