[Objective] According to the principle of giving priority to cultivated land and secondarily considering garden, forest and grass land in land management, the suitability evaluation of the agricultural land was carried out to provide a theoretical basis for rational using of the lands of Yantai City.[Methods] Taking Yantai City of Shandong Province as the study area, using the function of ArcGIS spatial analysis to extract evaluation factors as altitude, slope, relief degree of land surface from DEM data. Combining with soil thickness investigation, the best suitability evaluation index system of agricultural land were determined. Upon which, the distributional suitability rank map of cultivated land, garden, forest and grass land was generated, and the spatial distribution of agricultural land suitability level of Yantai City was formed.[Results] In comparison with the data of second land survey of the Yantai City, the major area of land using was cultivated land, took up about 33% of the total land and covered more than the suitable area. Actual area of garden was smaller than the suitability area, and the actual forest and grass land area was a little less than the suitable area.[Conclusion] The land using of Yantai City is not reasonable, and has a certain room to be adjusted.
