Soil physical and chemical properties may be altered in regenerating forests, which may affect site productivity and ecosystem services. In this study, soil physic-chemical characteristics were investigated in a series of regenerating Schima superba secondary forests in Qing Shigang Forest Farm, Hunan province. The correlations between the soil properties and the regeneration index were also examined in the studied sites. The result showed that the eight sampling stands were in different regenerating conditions with an order from poor to high condition as S-CP(0.46) < S-DC(0.52) < S-CD(0.64) < S-CL(0.68) < S-CM(0.69) < S-CQ(0.69) < S-PC(0.74) < S-CP(0.88). The best regenerating condition was found in the Schima superba and conifer mixed forests stands in the study area. Natural Schima superba regeneration was enhanced under acidic environments and in fertilized sites. The high regeneration indexes were found in those forest stands with high organic C, total N and total P contents in soils and low soil pH value and soil bulk density. No considerable relationship was found between the regeneration index and soil K content. The regeneration index was negatively related to soil bulk density (r=-0.86^{* *})and positively relative to soil water content (r=0.93^{* *}), soil organic carbon(r=0.90^{* *}), total nitrogen(r=0.88^{* *}), hydrolyzable nitrogen(r=0.83^*)and total phosphorus(r=0.78^*). The results obtained from the use of principal component analysis indicated that water content, organic carbon and total nitrogen in soils were critical factors in determining natural regeneration of Schima superba forests in the study region. Our results provide scientific basis and reference for restoration and sustainable management of Schima superba secondary forests.
