Report of Investigation on Fagus of Micangshan Nature Reserve

To investigate the forest resources storage of Fagus on Micangshan Nature Reserve the conven- tional of wild methods were used in this paper. The results showed that the forest area of Fagus was 7 064.8 hm2 at the reserve area, covered an area of above 40% Reserves. The total accumulation forestry of Fagus was 81g 600 m3 , and the preservative area of Fagus was the largest in domestic at present. In the protected area existing four kinds of this species, and they are F. longipetiolata, F. lucida, F. haya- tae, F. engleriana, respectively. However, the F. hayatae was most important in that four kinds of Fagus and the forest distribution area of F. hayatae was 5 923.3 hm2, the dominated forest area of F. hayatae was 2 511 hm2, and the total accumulation forestry of F. hayatae was 814 600 m3.
