Abstract: In order to understand the variation of carbon and nitrogen storage and the ration of carbon to nitrogen of Phyllostachys edulis forest with different modes of operation and operating duration, this study was designed to test the dynamic characteristics of carbon and nitrogen storage by typical sample method in Yongan city, Fujian Province and Anfu County, Jiangxi Province. The result showed that the carbon and nitrogen storage decreased in P. edulis forest with fertilization and increased in P. edulis forest with reclamation. The carbon and nitrogen storage of soil layer was the largest, followed by the vegetable layer for both the moso bamboo forests. The proportion of soil layer carbon storage was 63.25%-86.32% and the vegetable layer was 13.17%-35.15%. The nitrogen storage of soil layer was 94.44%-98.15% and the vegetable layer was 1.62%-5.12% . The carbon and nitrogen storage of moso bamboo system was affected by the carbon and nitrogen storage of soil layer. There was a significant difference for the moso bamboo carbon and nitrogen storage in different operating time. The carbon storage of moso bamboo with fertilization was in the order of control forest>moso bamboo forest with 13 years fertilization>moso bamboo forest with 5 years fertilization and the nitrogen storage was in the order of control forest >moso bamboo forest with 5 years fertilization >moso bamboo forest with 13 years fertilization. The carbon and nitrogen storage of moso bamboo forest with reclamation was in the order of moso bamboo forest with 3 years reclaim>moso bamboo forest with 10 years reclamatiom >control forest. The change of carbon storage was not compatible with the nitrogen storage. Thus the value of C:N was amplitude largely. The ratio of C:N was from 18 to 39 in forest with fertilization and was from 13 to 16 in forest with reclamation. The amplitude was more violently in forest with fertilization. Those changes may damage the site sustained productivity. The carbon and nitrogen storage increased due to treatment of fertilization and reclamation. However, the carbon and nitrogen storage of vegetation layer distribution pattern was different for different types of moso bamboo. The difference of the carbon and nitrogen storage implied the exclusive management measures can be designed for the P. edulis forest.

Key words: operating duration, storage of carbon and nitrogen, Phyllostachys edulis, C:N
