For studing the population structure of the Decapoda crustaceans of the Intertidal zone of Bushehr rocky shores, we collected biological speciments totally from 4 stations during 4 seasons, autumn (1386) to summer (1387). The sampling unit in this study was a 50×50(Cm) quadrate and the sampling was carried out randomly .The samples were sorted and fixed in the 10% etanol after transfering to the biology laboratory and then were identified by keys and other resoures. One of our aims in this study was calculation of species diversity and dominance. Further more, we measured some environmental factors such as Salinity, DO, tempreture, and pH with digital equipments. In this stady, we identified 8 species of 5 Decapoda families.The most species frequency contained Petrolisthes rufescence 51%, Pagurus sp. 22%, Metapograpsus maculates 7%, Pilimnus sp. 6.5%, shrimpa 3% and other species 10%. We also used ecological index for comparing species diversity. According to the results, frequency and diversity rate redused in cold seasons ( autumn & winter). The temperature was an important factor in this changes. Two stations (C & D) had the most diversity and least pollution. In the total period , Petrolisthes rufescence had the highest Dominance frequency.
