摘要
提出的人工林密度效应蓄积量的改进模型具有幂次数可变、适应性较强和实际应用较方便等特点 .采用该模型对闽北马尾松人工林密度效应进行拟合 ,结果表明 ,比前人模型拟合效果更好 ,可为马尾松人工林营林与密度管理提供科学依据 .
The established modified model of volume for stand density effect in pinus massoniana plantation has such characteristics as variable power times, stronger adaptability and convenient application. The stand density effect of pinus massoniana plantation in northern Fujian Province was simulated by the modified matel, the results show that the modified model has beffer effect than those previous models, which provides the scientific basis for pinius masoniana's cultivation and density management.
