Abstract

The Khan-chay watershed in TAROME-OLYA of ZANDJAN province with an area of 20243 hectares is located in the north of ZANDJAN. The lowest and highest altitudes range from 400 to 2763 meters above sea level. The mean annual precipitation varies from 700 mm at the top of the mountains to 200mm in Ghezel-uzan river area.For a floristic study of the area plant specimens were collected and identified. The LIFE FORMs as well as geographical distributions of the species were determined. FLORA in this region include 57 families, 195 genera and 310 species. The larger families are Compositae (45 species), Papilionaceae (37 species), Graminae (34 species), Labiatae (25 species) and Rosaceae (20 species), respectively. One hundred and eighty nine species are new records for the FLORA of Khanchay. LIFE FORMs include Hemicryptophytes (56.8%), Therophytes (12.6%), Chamaephytes (11.6%), Phanaerophytes (11%), Crytophytes (7.7%) and one semiparasite specimen. Phytogeographical elements in this region were determined as: 71/3% IRANo-Turanian, 8/7% IRANo-Turanian and Euro- Siberian, 5/5% IRANo-Turanian and Mediterranean, 4/5% IRANo-Turanian, Mediterranean and Euro- Siberian, 3% Cosmopolite, 1/6% IRANo-Turanian, Mediterranean and Saharao-Sindian, 1/3% Eurosiberian and /3% IRANo-Turanian and Saharao-Sidian.
