摘要：Taking Chinese fir as researched object and Richards function as basic model,the models of single site index and polymorphic site index were established to analyze the affect of stand standard age on the result of site quality evaluation with the ways of ANOVA,multicompare,curve tourning point and change of dominant tree height between site classes.The result showed that with the site class getting higher,curve tourning point volue getting lower,it was impossible to define the standard age before stand growth reached steady.If stand standard age is too small,it would lead to a higher site calss in polymorphic site index evaluation;The difference was notable among stand dominant height from difference standard age,if standard age is too small,it would lead to a lower site class in single site index evalution.Taking the age steady-grown stand as standard age would not make notable affect on the result of site quality evaluation.

The result showed that with the site class getting higher, curve tourning point volue getting lower, it was impossible to define the standard age before stand growth reached to a higher steady. If stand standard age is too small, it would lead site calss in polymorphic site index evaluation; The difference was notable among stand dominant height from difference standard age,if standard age is too small, it would lead to a lower site class in single site index evalution Taking the age steady-grown stand as standard age would not make notable affect on the result of site quality evaluation
