| Abstract: | In this paper, on the basis of summirizing up the works of previous researchers and the natural conditions and productive features of the alluvial plain and The Regulations of The Agricultural Lands,the soil effective coefficient of different land types is defined by using the sliding average and the double regression method and its importance in the grading of agricultural land is analysed. |
