In addition, the paper analyzed and simulated growth process of stand basal area, volume and biomass under different initial planting density for Cunninghamia lanceolate, plantation.
另外，对杉木不同初植密度下林分断面积、蓄积和生物量的生长过程进行了分析和模型拟合。
The results indicated that it is unbiased to estimate basal area of stand but inefficient when estimating stems per hectare by point sampling.
结果表明：点抽样估计林分断面积是无偏的，而估计林分每公顷株数效率不高。
The basal area growth model is the most important one in the integrated stand growth model.
断面积模型是全林模型系统中最重要的模型。
