Availability and evaluation of European forest soil monitoring data in the study on the effects of air pollution on forests

摘要: Abstract: In the study of air pollution effects on forest ecosystems, solid soil data such as cation exchange capacity, base saturation and other exchangeable fractions, texture, moisture, weathering rates, C/N ratio variables form an important information for many impact models. This paper shows some possibilities limitations that European countries collected systematic Level I intensive permanent II monitoring plots within ICP Forests programme. The date from a first inventory in 1990s second more than 10 years later. Both surveys were conducted following common manual sampling analysis soil. An example changes pH(CaCl2) floor mineral 2000 till depth 80 cm between two is presented. this period significantly increased very acid soils [with below 4.0] but further decreased with above 4.0. Following trend pH, low buffering capacity (soils 20% inventory) reference values 20%. There both decrease pH Arenosols Podzols. Podzols decreasing could not be established soil, though persisted number layers Arenosols. only consistent increasing when stratifying according to WRB groups was seen Luvisols Cambisols.
