بررسی نقش جنگلکاری در احیا اکوسیستم های جنگلی آسیب دیده از جنگ خلیج فارس

In order to approach the goals of project, "Restorative Reforestation practices infores/ ecosystem of Iran damaged by Kuwaiti burning oil wells" according to proposal, some land survey in southern provbJces of Iran, affected by environmental pollution caused by Kuwaiti oil-. wells burning were done associated wiath project colleagues support. Regarding to prepared maps producted using sqtellite images and further ground check points, the polluted sites, were classified and the treatment plots located at each class. In this regard, six sites were selectedfrom provinces of Khuzestan, Fars and Boshehr. Tree genus are: Eucalyptus, Prosopis, Po po/us, Da/bergia and Acacia with regarding to ecological condition,s (soil, climate, ...), as Randomized Complete Block Design Experimental with different NDVI Statistical information such as: Tree height, diameter, annual growth of diameter, leaf samples, soil samples i'om different depths(O-30, 30-60,60-90 em) under related crown cover of each species were selected, also ground _ cover in each site were gathered and identified . Collected data analyzed by SPSS and Excel softwares. The results show that rules of trees on decreasing pollution, completely related to trees characteristics, site factors (environmental factors) and also rate and concentrations of pollution. In regions that pol/utiDn was high, NDVI is" h" and site soil is high fertility and no water deficit, native trees such as Po po/us euphratica and Dalbergia sissoo are superior to exotic species, because of their ability to uptake more soil's material. Among exotic trees, Eucalyptus . species are superior to others. These species have more rules in decreasing of pollution. Investigations on soil Pb element in difftrent profiles and six sites, showed that: the capacity of Eucalyptus ssp. For soil component updating is better than others species. After that, Acacia spp. and Dalbergia sissoo are more successful to decrease pollution sol/. Additional results indicated that when the pollution degree is high, Eucalytus microtheca enable to uptake massive Pb, Zn, Cd compounds and restored them in their leaves. .
