杉木、马尾松、木荷纯林及其不同混交林生长状况的分析

Analysis on Growth Conditions of Cunninghamia lanceolata, Pinus massoniana and Schima superba Pure Forests and Their Different Mixed Forests

对杉木、马尾松、木荷纯林及其习种不同的混交林分生物量和空间分布状况的调查分析，揭示混交林与生物量间的相互关系，以及生物量的空间分布规律，以便合理利用土壤、防止地力衰退，保持林业永续利用。

By investigation and analysis on the biomass and spacial distribution of Cuninghamialanceolata Pinus massoniana Schima superba pure forest and 4 kinds of mixedforests, relationship between biomass and mixed forest and law of spacial distribution of thebiomass were revealed,so as to rationally utilize, protect from degeneration of soil fertility andkeep sustainable utilization of forestry.
