Forest soil acidification assessment using principal component analysis andgeostatistics

Popis výsledku v původním jazyce

Soil acidification and consequent Al release is a problem particularly under forests in mountainoujs areas of the Czech Republic. It is controlled by a number of factors,like acid deposition, forest type, parent rockaltitude. etc. The Jizera Mountains region presents an arela heavily influenced by acidification and forest decline. This pper focused on theeffectof stand foactors on spatial distribution of soil characteristics of the surface organic(O)and sub-surface (B) horizons from 98 sites using a combination of principal component analysis (PCA) and goestatistics. In the PCA, five principal components (PC) describing more than 70 % of total variation were selected. The properties of the O and B horzons (pH,C,N, and S content, potentially dangerous Al forms) were in most cases separated, suggesting different processes and effects in each horizon. Spatial variation of PC scores was analysed using variogram,s maps of their distribution were creatd using kriging. Spatial correlation wit
