Abstract:The calorific values,ash contents and nutrient compositions in the leaves of the secondary southern subtropical monsoon evergreen broad leaved forest and 13 forest edge plants on Gushan Mountain in Fuzhou were studied.The rank order of the average ash contents in the leaves were shrub layer(10.0%)>herbaceous layer(8.5%)>tree layer(6.7%).The mean gross calorific values(GCV)increased from the herbaceous layer(16.89 KJ/g),to the shrub layer(17.75 KJ/g) and to the tree layer (19.79 KJ/g).The ash free calorifi...
