The agricultural sector is one of the main pillars of the economy, the development of which will lead to the development of the economy. However, factors such as the fragmentation of agricultural lands reduce the productivity of agricultural products and labor. Therefore, the present study with a developmental-applied nature and descriptive-analytical method was performed using remote sensing data, field study and available statistics to investigate the distribution of agricultural lands in Taj Amir village and the effect of this distribution on agricultural land productivity of this village. In this study, using satellite imagery (Sentinel 2 and IRS_P5), a land use map was extracted with an object-oriented technique and agricultural land plots were modified in the AutoCAD map software environment. The field study of agricultural land ownership was determined in 2015, and based on this, the ownership of the 1940s was determined and generalized to the agricultural land map. Then, using land metrics, the amount of change and using LCPA, the type of land dispersion and evolution were obtained. The results showed that the area of agricultural lands has decreased and the type of changes in the class of agricultural lands is also descriptive. The results of field studies also showed that the factor of land reform had no effect on land dispersion but the factor of inheritance was effective. Thus, 1735 plots of land with 62 owners in the 40s have reached 2180 plots with 257 owners in 2015. A review of statistics also showed that the amount of productivity has decreased.
