| Abstract: | In the natural Chinese fir and broad leafed forests, the effect of soil nutritional elements on the dominance of Chinese fir and other dominant tree species was different with tree species. Chief nutritional elements of soil influencing Chinese fir's dominance were slow release potassium, C/N ratio, organic matter; that influencing that of Schima superba were total potassium, available potassium, C/N ratio; that influencing that of Castanopsis eyre were organic matter, total nitrogen, available nitrogen, total phosphorus. The chief nutritional elements were different with dominancd of tree species and some of their direction of action to the dominance were same and others were not. |
