摘要： <正>本文采用Chapman-Richards函数拟合树高和年龄的关系,用三种不同方法编制杉木地位指数表。结果表明,多形地位指数曲线的精度比单形地位指数曲线有很大提高。从实用目的出发,编表时采用了地位指数曲线加密处理。

Abstract: By adopting Chapman-Richards function, this paper describes the height-age relationship and uses three different methods to compare site index table for Chinese fir. The test results indicaed that the precision of polymorphic site index curves was greatly higher than that of anamorphic site index curves. The density of polymorphic site index curves was added for the sake of practicability.
