Determination of trophic status is one of the methods for assessing ecological balance of wetland ecosystems, because sustainability and productivity based on these unique ecosystems require proper monitoring and control of their environmental conditions. Therefore, biological and ecological studies are necessary before any activity is established. Tanudar Wetland with an area of 1000 hectares is one of the largest wetlands of Lorestan Province, 10 km northwest of Dorood. In this study, physical and chemical characteristics of Tondar wetland sampling were used to evaluate the nutritional status of Carlson (TSI) based on total phosphate (TP), total nitrogen (TN) and phosphorus to nitrogen (PN) Sampling of Tanudar wetland was used in summer of 2019. The results showed that based on the Carlson Trophic Index (TSI), trophic wetland Tanudar level is in eutrophic conditions. wetland Tanudar to its location, natural conditions and hydrological conditions, the is mainly drained from the highlands of Silakhor plain and tira River Dorood, Therefore, any upstream loading such as orchard development, diversified recreational harvests in the river, increased levels of dark river water pollution caused by municipal, industrial wastewater, and point source pollution sources such as warm-water fish ponds have crossed the Tanudar wetland. And it wound deeper on the current unstable body. Therefore, in the current conditions, the quantitative and qualitative provision of the wetland ecological right of the wetland is one of the most obvious requirements and management issues of the wetland.
