The need to understand and predict the often-complex impacts of anthropogenic perturbations on aquatic and terrestrial ecosystems has lead to the emerging and interdisciplinary field of environmental modelling. The primary objective of the proposed research is to predict the impacts of sulphur and nitrogen deposition on terrestrial and aquatic systems. More specifically, research will focus on the development and application of critical load and dynamic biogeochemical models to predict the response of ecosystems to changes in anthropogenic emissions of sulphur and nitrogen. The research will emphasise state-of-the-art modelling as a tool for environmental management to support ecosystem integrity.

由于需要了解和预测人为扰动对水生和陆地生态系统往往复杂的影响，因此出现了环境建模这一新兴的跨学科领域。拟议研究的主要目标是预测硫和氮沉降对陆地和水生系统的影响。更具体地说，研究将侧重于开发和应用临界负荷和动态生物地球化学模型，以预测生态系统对人为硫和氮排放变化的反应。该研究将强调最先进的建模作为环境管理的工具，以支持生态系统的完整性。
