| Today, many satellites over land cover and land water produce high-quality images of different uses. The conditions for access to these images are such that it can be used for several years to study the phenomena of aquatic ecosystems, such as wetlands, and at the same time identify their changes. Length- The temporal and spatial distribution pattern of primary production is useful for studying global climate change. In this study, using Landsat images from 1985 to 2017 and their initial processing, the average initial production (based on O.E.C.D) for Choghakhor International Wetland was determined. The results show that the wetland is in terms of chlorophyll-a and secchi disk depth (SDD) in the middle of mesotrophic and towards eutrophication. |
