Study on the Biomass and Productivity of the Plane Seeding Pinus Massioniana Forests
Yao Dong-he · Journal of Hunan Environment-biological Polytechnic · 2001
The results showed that in 16 - year- old different stand density Pinus massoniana forests, either the single - tree biomass or the stand biomass was obviously reduced with the increasing of the stand density , and the single - tree biomass of the low stand density had increased by 18.33kg and the stand biomass increased by 21.81t/hm2 morn than those of the high stand density. The biomass of the sterm, branch, leaf, bark, and root was reduced with the increasing of the stand density , and showed the regularity Ws Wr Wb Wba W1; . The net productivity of the low stand density was 1.40 times as much as that of the high stand density.
