%X The relation of the canopy structures of five-years old Chinese firs (Cunn-inghamia lanceolata) to their biomass has beend iscussed in the paper. Some results obtained are as follows. 1. In the same stand there is no obvious difference in the proportion ofthe different parts between trees. Trunk has the highest propertier--36%,needles--32%, branches--17% and underground part has the lowest proportion--15% on the basis of dry weight.2. The needle dry weight density cf canopy of five-years old Chinese firs va...
