| Abstract: | According to the data of wood analysis and biomass invcstigation, wc analyse the relationship among scotch pine stock, the growth of volume and its density, thc relationship between bio-productivity and its density as well as the law of the distribution of biomass of various organs of the scotch pine. The conclusions showcd that the stock, volume, growth, bio produetivity and its density were interrclated closely. The appropriate density was 620--820 individuls / hm2 of mid-aged trees. The distributions of biomass on various organs werc different at different age stage. This paper gave the evidence to value artificial scotch pine, its structures and functions. |
