In order to characterize the variance in sap flow within and between trees,and to quantify the water use of whole tree and of forest stand,Granier s thermal dissipation probes were applied to measure sap flux density (Js) in 14 sample trees in an Acacia mangium forest in Heshan Station,Guangdong.

Microelements Distribution and Biological Cycling of Acacia mangium plantation in Nanning,Guangxi

The water-holding capacity of canopy,vegetation layer under canopy and litter layer,the water-holding capacity and permeability of soil as well as their changes with growth of stands in Acacia mangium plantations of 3 different age classes(4-year-old,7-year-old and 11-year-old)were further studies.

The radiation energy environment,photosynthesis and respiration rate,productivity,biomass and caloric value were measured in a Acacia mangium plantation at Heshan,China.

The differences of soil chemical properties and enzyme activities between rhizosphere and non-rhizosphere soil in Acacia mangium plantations were comparatively analysed,and their changing regularity during Acacia mangium development was also studied.

An experiment was conducted to study the biomass productivity of Acacia mangium plantations of different age classes (4,7 and 11 years old).
