Field Survey Based Models for Exploring Nitrogen and Acidity Effects on Plant Species Diversity and Assessing Long-Term Critical Loads

摘要: Empirical critical loads are based on current evidence for relationships between the rate of pollutant deposition and changes to ecosystems observed in experiments surveys. When considering longer-term change effects after periods excess load, dynamic modelling approaches useful. This chapter describes two soil-vegetation-floristics model chains, similar concept, that being applied Netherlands UK explore pollution scenarios calculate long-term acidity nutrient-N. These chains consist models soil vegetation biogeochemistry, combined with environmental suitability define realised niche species or assemblage. The described this empirical (MOVE, PROPS, MultiMOVE) assemblage (NTM3) occurrence conditions, defined multiple axes. They driven by different biogeochemical models, forming SMART2-(SUMO2)-PROPS/NTM3 MADOC-MultiMOVE. In these detail, applications scenario exploration setting demonstrated.
