Abstract :

Land use is one of the most important factors that Man influences the environment through it. Changes in land cover and land use have direct effects on climate change, and there is a reciprocal and complex relationship between climate change and land cover change. Therefore, it is important to monitor land use changes for management and Presentation of management plans. Today, remote sensing and geographic information systems are widely used, especially in dealing with multiple geographic data and interpreting the vast area of the earth's surface. In this way, remote sensing data can be used as a suitable substitute for unregistered and past data, such as land use data and its changes over time periods, and serve as basic information for other studies. The purpose of this study was to investigate land use changes in the Perishan wetland area from 1990 to 2015 using a remote sensing technique and investigate the relationship between these changes with groundwater levels and precipitation. The results of this study showed that the farmland area increased by 1,371 hectares from 1990 to 2015, while the groundwater level decreased by 14.72 m. Also, the results of this study showed that the changes in land area of agriculture are inversely related to groundwater level and increasing the area of agricultural land leads to more groundwater discharge and lower groundwater level.
