Abstract: Usingsample-plot surveyand soil sample analysis, wedetermined thegeneral situation ofwoody biomass(WB), litter biomass(LB) and soil nutrients(SN) including organic matter(OM), total nitrogen(TN), total phosphorus(TP) for three plants(Pinus tabuliformis, Populus davidiana, Quercus liaotungensis), and analyzed the relationship between biomass(WB, LB) and SN as well. The largest WB was that of P.tabuliformis(2.3547 t·hm-2), followed by P.davidiana(2.0785 t·hm-2) and Q.liaotungensis(1.1373 t·hm-2). The largest LB was that of P.davidiana(4.7975 t·hm-2), followed by Q.liaotungensis(2.1399 t·hm-2) and P.tabuliformis(0.5250 t·hm-2). The forest soil classification indicators were OM and TP with the standard level of 4-5 and 1-3, respectively. For the analysis and comparison result of forest SN, the largest content of OM was that of P.davidiana, followed by Q.liaotungensis and P.tabuliformis, while largest contents of TN and TP were P.davidiana, followed by P.tabuliformis and Q.liaotungensis. We also analyzed the correlation between SN and WB and LB, resulting in that the correlation of all three plants with a highly significant relation(P<0.01), and the correlation among OM, TN and TP of all three plants also was significant with a good synergistic effect(P<0.05).
