Abstract
Plants and animals biodiversity affects the ecological functions of natural and agricultural systems. Therefore, reduction of biodiversity can be a serious threat for survival of ecological systems. Data were carefully provided from Ministry of Agriculture of Iran during 2003-2012. The results of diversity indexes indicated high biodiversity in Kermanshah province. They showed that a diversity of agricultural products, including field and horticultural crops, are cultivated in Kermanshah province. Of the different counties in the province, Paveh and Harsin had the highest Shannon index while Qasr-e-Shirin had the lowest value. The trend of Shannon species diversity index of the agricultural crops showed significant temporal variations over 2003-2012 and also among the counties of the province. Shannon species diversity index for the agricultural crops in the province over 2003- 2012 showed the highest and lowest values in 2010 (1.77) and 2005 (1.49), respectively. The overall trend of Shannon index of the agricultural crops of the province was increasing during these 10 years.
