Investigation of Qualitative (Qualitative), Diversity and Richness in Chaharbagh Abbasi, Chaharbagh-e-Bow and Abbas Abad streets in Isfahan

Nowadays, maintaining and developing of Green spaces in order to improve life quality and sustainability of the cities is very important. By measuring and reviewing the qualitative and quantitative characteristics of trees can be identified more resistance species and used in the future plans. In this study, quantitative characteristics (tree diameter and height) and decay have been examined. The diversity and richness of tree species were calculated on the margins of Chaharbagh Abbasi, Chaharbagh Paein and Abbas Abad streets, using PAST software and Ecological-Methodology, and compared with each other. The results showed that in Charbagh Abbasi Street, Margalof and Munnikh species richeness were 0.604 and 0.182 respectively, Chaharbagh Paein Avenue, respectively, was 0.21 and 0.643 respectively, and Abbas Abad Street, respectively, was 0.624 And 0.202. Also, the Simpson and Shannon-Weiner variations for each of the three streets were equal to 0.445, 0.721, 0.4487, 0.0899, 0.894 and 0.739 respectively. In general, the results indicated that Abbas Abad's biodiversity and bioavailability are relatively more than the two other streets.
