Today, studies on climate change Impacts have shown that climate is changing in most areas, and these changes pose risks to the health, economy and natural communities, and according to forecasts, this trend is expected to increase pressure on communities. Therefore, to adapt to the new conditions, it is necessary to study the process of change and effective and influential factors to identify and reduce the risks. This study was conducted on Gavkhoni basin including 7 reaches and the period of 1986-2018. 20 synoptic stations, 28 climatology stations and 107 rain gauge stations were used to study climate change. After correcting and filling missing data, for the parameters of monthly precipitation, maximum and minimum temperature of each station, z-factor was calculated by using Mann-Kendall test and the trends calculated by elevation models, DMSP night images and GHSL product images by GEE platform and Sen’s slope and then by using cokriging method with The digital elevation in SAGA software. We Also used Landsat 4, 5, 7 and 8, ASTER and SRTM digital irrigated and rainfed crops, poor and good pastures and water in seven reaches random forest method with 50 branches and QGIS software to study Vegetation changes and Landscape parameters related to the LUC percent, the area of ??the largest patch, the number of and the basin. Then, the correlation of annual time series of climatic patches and the Clumpiness index of barren lands, mountains, orchards, parameters and land landscape parameters was investigated using the Spearman method in Rstudio software from lag 0 to 9. The annual study showed that rainfall with an average of -3.9 mm per year decreased in the three western reaches of the basin and the minimum and maximum temperature in the basin. The results also showed increased with a total average of 0.0425 °C and 0.029 °C resources with a trend of / 026 decreased. It is also shown, despite the rainfall that the urban land-use area increased 0.044 percent per year and the water especially the use of tree covers in the reaches 3 and 4. Also, rangeland decreased in the west of the basin we have increased in water uses land covers, due to the increasing trend of temperature in this area. It also seems that due coverings have become denser in the western reaches, which seems to have been to the loss of water areas in the east of the basin, these areas are increasing in the maximum temperature trend more rapidly than in other areas.
