Effects of forest conversion on carbon and nitrogen storage and distribution of the aboveground part of trees and soil.

Abstract

Abstract: Forest conversion affects ecosystem carbon (C) and nitrogen (N) storage. The accurate assessment of forest C and N storage is an important theoretical basis for forest C sink management. In this study, we measured C and N storage in broad-leaved evergreen natural forest (BE),Phoebe bournei plantation (PB), Cinnamomum bodinieriplantation (CB), and Cunninghamia lanceolata plantation (CL) at Nanping in Fujian Province. The C and N storage in aboveground biomass and soil was compared. The results showed that ecosystem C storage of AF, PB, NS, and PA was 215.68, 207.50, 120.14, 207.53 t·hm^-2, and N storage was 7.73,11.50, 9.20, 9.05 t·hm^-2, respectively. The C and N storage in aboveground biomass was the highest in BE, while CL had the highest soil C and N storage. C∶N ratios in both leaf and surface soil were highest in CL. Spatially, the conversion of natural forest to plantation forest altered C and N distribution patterns. The natural forest ecosystems had higher C and N storage, which should be protected in future management.
