This paper conducted a comparison test on the measures,the existing litter biomass and its nutrient content,the soil Physicochemistry properties,ect of the Castanopsis hystrix secondary forest(CHSF,12～15 year’s old) and the similar Cunninghamia plantation (CP,15 year’s old) in Donglan County,Guangxi.The results show:(1)By comparison,the mean height-breast diameter,the mean tree height and the mean volume of the CHSF in the middle and bottom gradient are 1.6～4.0 times higher than those in the upper-gradient.(2)The existing litter biomass,the maximum net absorbing water and the main nutrients content(N,P,K)in the different CHSF forest site respectively especially those in the CHSF middle-gradient forest are higher than those in the CP forest.(3)The CHSF soil(0～40 cm deep)volume density in different forest site is 0.785～(1.349 g/cm~3).However,the maximum capillary moisture capacity and the soil aeration in the CHSF forest site are slightly higher than the CP forest site.(4)The soil organic matter(0～40 cm deep) of different CHSF site is slightly higher than that in the CP site.The total nitrogen content,the dissoluble phosphate and the dissoluble kalium content respectively are 2.39～(4.16 g/kg),0.90～1.40 mg/kg and 29.04～(41.44 mg/kg).It shows that the CHSF has a significant effect on the benefits of society,economy and ecology in these regions.
