The basalarea 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。

The results indicated that it is unbiased to estimate basalarea 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。

Meanwhile, the result showed by random effects test demonstrated that basalarea models of provenances planted on the same region was of no significant difference.
