%X Betula albo-sinensis forest is an important type of forest vegetation of the Taibai Mountain region, distributed From 1950 to 2650m on the south slope and from 2200 to 2750m above sea level on the north slope.Using clustering analysis(UPGMA),twenty plots of Betula albo-sinensis forest were classified into seven types:i) B. albo-sinensi Quercus liaotung-ensis forest; ii) B. albo-sinensis Q.liaotungensis Pinus armandii forest;iii)B. albo-sinensis P. armandii forest; iv) B. albo-sincensis forest;v)B. albo-sinensis P armandii B. utilis fargesis forest;vi) B. albo-sinensis B. utilis Abies jargesii forest;vii) B albo- sinensis B. utilis forest.Seven types of B,albo- sinensis forests were regularly distributed in this order along the altitudinalgradient, but B. albo-sinensis forest always dominates and the forest structureis relatively stable.The analysis of the Bctula albo-sinensis population structure,dynamicsand natural regeneration indicated the Betula albo-sincntis forest was in a de-grading stage.Betula albo-sinensis forests are mature or over-mature at present,artificialregeneration should be strengthened.
