摘要：Because of its wide area and geographical diversity, Iran has a nature with different types of vegetationspecies. Located in desert belt, on one hand, and facing with serious ecosystem threats such as draught,soil erosion, decreased vegetation of desert areas, and overuse of vegetation in the vulnerable areas, on theother hand, has led to the ever increasing attention to Iran ecosystems. In this paper, it is tried to have asuitable estimation about the vegetation energy potential of Iran. Considering the scarce vegetation of Iran,expansion of this vegetation might be a considerable contribution to increasing this potential, whichconsequently results in the improvement in environmental advantages, such as reduction of soil erosion,increase of herbal fertilizers, fodder for stocks feeding, and oxygen, lowering the shifting sands, and thedecrease of dunes and microspores. In this regard, various ecosystems of Iran were selected and their totalpotential was estimated for one energy unit, considering biomass content in every hectare of land. Moreover,considering the Iran’s potential in the production of energy products, vegetation expansion by planting theJatropha was studied in this work in three scenarios. The results of this study indicate that Iranian ecosystemshave an annual 2,695,757 billion calories which equals to 1.8 billion barrels of crude oil. Moreover, theresults of these scenarios evince that a 5% increase in energy generating vegetation such as Jatropha in thedesert areas, it is possible to provide 18% of domestic gasoil demand. Hence, it is required to have a supportupon creation of energizer vegetation products, as well as supervision of state organizations for creation ofa suitable vegetation cover in the entire country.
