| Soil is one of the most important natural resources and foundation of formation and development of human civilized societies. Sediments are also important at receiving organic matter, material budgets and distribution of benthic organisms. As part of the ecological study of Choghakhor Wetland where located in Chaharmahal-o-Bakhtyari Province, some physical and chemical characteristics of sediments in this wetland were studied in relation with benthos environment. Sampling was performed in 10 stations with 3 replicates in each station since April 2010 to March 2011. The results showed that wetland sediments texture at different stations was not differeny and sediments component showed no significant differences between the stations. But the components showed significant differences between the stages. There was no from spring to winter (timing change’s) amounts of organic matter increased and showed the significant differences between seasons. Also sediment’s moisture percent and organic matter in different seasons showed significant differences. There was no significant differences in the sediment texture between the season’s .The Pearson correlation coefficient showed positive correlation in the 0.01 level between percentage of organic matter and sediment moisture that indicating a high capacity for water storage in organic soils |
