Chemical weathering in Taiwanese catchments: Towards quantification of the controls on chemical weathering fluxes.

台湾岛提供了一个理想的天然实验室，用于研究热带条件下的高物理侵蚀过程。在这里，通过与土壤和基岩反应来控制河水成分的化学过程的运作，对当地和全球来说都是最不了解的，但也是至关重要的。迅速侵蚀的山地环境贡献了输送到海洋的大部分溶解和颗粒物质，并对缓和地球长期气候的反馈负责。它们还受到包括山体滑坡、地震和水库快速蓄水在内的极端自然灾害的影响，它们维持着可能对干扰特别敏感的生态系统。所有这些过程都取决于土壤形成的方式，在这种条件下，土壤物质会迅速地，而且往往是断断续续地从景观中移走。因此，了解这种在快速侵蚀环境中形成土壤的化学过程对当地环境和全球了解对地球表面环境的控制都是至关重要的。

The island of Taiwan offers an ideal natural laboratory for studying processes at high rates of physical erosion in tropical conditions. Here the operation of the chemical processes that control river water compositions by reactions with soils and bed rock is least well understood and yet critical both locally and globally. Rapidly eroding mountain environments contribute the majority of dissolved and particulate matter transported to the oceans and are responsible for the feedbacks that moderate Earth's long-term climate. They are also subject to extreme natural hazards including landslides, earthquakes, and rapid reservoir filling, and they maintain ecosystems that may be particularly sensitive to disturbance. All of these processes depend on the way that soils are established under conditions where soil material is removed rapidly, and often episodically, from the landscape. Understanding such soil-forming chemical processes in rapidly eroding settings is consequently critical both to the local environment, and to the global understanding of controls on the Earth' surficial environment.
