BIOMASS CHANGES OF AN ACACIA MANGIUM PLANTATION IN SOUTHERN CHINA

Abstract

Acacia mangium has been planted in large areas of southern China ever since its introduction into China in 1979. This article reports on A. mangium biomass accumulation over  a period  of 15 years in a plantation in southern China. The biomass of A. mangiumn increased from the first to the seventh year, after which the growth slowed down. Eleven-year-old A. mangium can facilitate the conversion of degraded lands into mixed native species forests. This paper also points out that N and P deficiencies may be an inhibitive factor to biomass growth.
