The research aims to analyzed the composition and structure of vegetation to determine the index of diversity in urban forest pekanbaru. The research is located at Thamrin Street Pekanbaru-Riau. The urban forest has a total area of 6.1 hectares. The research is a survey of the quadrant method and using simple random sampling technique. The analyzed use Shanon-Wienner formula to find the value of density , frequency , dominance and importance value index. The results showed the forest area of Pekanbaru has a level of tree vegetation diversity index is 2,83 which is classified in the middle criteria . Pole vegetation diversity index is 2,24 which is classified in the middle criteria. Sapling vegetation diversity index is 1,91 which is classified in the middle criteria. Seedling vegetation diversity index is 2,02 which is classified in middle criteria. Keywords: analysis of vegetation ,index of diversity, urban forest
