Profiles of Soil Carbon,Nitrogen of 23 a Mixed Plantation of Schima superba and Chinese Fir
The distribution profiles of soil carbon,nitrogen characteristics of 23 a Chinese fir pure stand(CS), Schima superba pure stand( SS) and the mixed plantation of Schima superba and Chinese fir ( MS) were explored. Results show that:in the upper soil (0~10 cm) ,N content of CS,SS,MS are the highest and CS>SS>MS,and C,N of MS are significantly higher than those of CS and SS(P<0. 05);but in the deep layer soil,there was no significant difference among 3 types of stands (P>0. 05). Compared with pure forest,Chinese fir and Schima superba mixed forest in surface soil on soil carbon, nitrogen content has a significantly improved. This may be mixed forest of Chinese fir and Schima superba has changed the structure of canopy, which is favorable to decomposition of leaves.
