Abstract: The species diversity and spatial pattern of Pinus tazoanensis population in Wuyishan Mountain in different elevations were studied．The results show that there is no obvious rule between the species diversity and spatial pattern in the lower elevation for people’s disturbance；with the increase of altitude，the species diversity indices ，richness and eveness decline．the growth of Pinus tazoanensis population is restrained．The distributive pattern of Pinus tazoanensis population be longs to clumpy distribution in the higher elevation．
