Abstract

The results of the investigation about the biomass, the increment and the quantity of the litter of secondary Schima superba forest on the south slop of Beigao mountain in Hangzhou were as follows: ① The tatal biomass of the stand was 126.649 tons per hectare in which the tree stratum, regeneration layer, shrub layer, field layer and the litter layer accounted for 80.16, 5.67, 3.84, 4.76 and 5.57 percent respectively.② In the tree stratum, the biomass of boles, branches and leaves were 53.591, 16.996 and 4.835 tons per hectare and made up 70.95, 22.50 and 6.40 percent of the biomass above the ground. The biomass of roots was 18.474 tons per hectare which accounted for 29.76 percent of the biomass below the ground. ③ This forest had the annual increment of 28.474 tons per hectare in which the increment of tree stratum and regeneration layer made up 68.19 percent and 10.54 percent. ④ Annual quantity of litter weithted averagely 5.848 tons per hectare in which the leaves were 79.49 percent. There were two top periods of the litter: one was from February to April and another was from Augsut to September.
