主　　题：Energy Larch Community 

摘      要：By means of calorimctry measurement, the caloric values of various components, the standing crop of energy, net energy production and energy conversing efficiency of an artificial dahurian larch community at Laoshan Plantation Experimental Station of Maoer Shan Forest Farm in the eastern part of northeast China were determined and studied in the present paper. The result of the experiment were as follows: (1) caloric value varied with plant species and plant organs, in general, the order of caloric value was tree, shrub and herb, and for different organs, was leaf, branch, trunk (stem), bark and root. (2) The standing crop of energy of larch community and tree layer were 269.719 × 1010J/ha. and 264.440×10l0J/ha. respectively. There existed different distributions of energy in various components and different layers. (3) Net energy production of larch community and its tree layer were 264.346 × 108J/ha.a and 243.678 × 108J/ ha.a respectively. To the photosythctical active radiation on the stand, its energy conversing efficiency was 2.2990%. Compared with other common forest communities in nature, artificial larch community has a relative larger energy production and higher conversing efficiency.
