| Abstract: | Standing crop in Robinia pseudoacacia L. community at loess Plateau area of north Weihe river was 85.193 ton/ha, in which 92.8% of trees layer, 5.8% of litter, and 1.4% of understory and herb layer. The above-ground standing crop of trees layer is the funtion of standing crop of trunks.The net production of trees layer was 8.054 ton/ha, yr., in which the crown layer was 55.3%, the trunks was 29.4%. The above-ground net production of individual tree shot up with the adding of leaf area. The productive efficiency of leave in stand and individual trees were about equivalent. |
