Biodiversity is one of the important indices for assessment of agroecosystems sustainability. Unfortunately, the benefits of biodiversity are ignored in the agroecosystems. Therefore, the present study was conducted for evaluating horticultural crops biodiversity of Kermanshah province in the Campus of Agriculture and Natural Resources of Razi University during 2012. Data were collected by the Ministry of Agriculture of Iran. The results of biodiversity criteria indicated high diversity among the fruits species cultivated in the province. The number of cultivated species was estimated 24. Among the cities, Dalahoo, Paveh, Harsin ,Salas-e-Babajani and Ravansar had the most Shannon index while Qasr-e-Shirin exhibited the least species, Shannon index, diversity evenness and Sorensen’s similarity index. Long-term mutual effects of different climatic elements on living organisms create fixed and specific biologic conditions so that in each climate we find certain plants with particular adaptations which have similar and specific growth and developmental characteristics and of a predefined tolerance against environmental factors. With the increase of altitude and the environment becoming mountainous, the cultivation of horticultural crops increased. Kermanshah Province, due to the territorial diversity of species diversity was sufficient for horticultural crops.
